High bandwidth optical wireless transmission for secure communication
Current LiFi systems use wide beams to illuminate an area in which the user can move freely. Multiple users share the available bandwidth and the LiFi systems assigs time and frequency blocks for each of them. Going beyond the bandwidth limitation that is created through that, requires a new approach based on transmitter arrays. By arranging several transmitters in an array and using a lens for imaging, mobile users will receive data through individual narrow beams. The goal of the project is to design a profound LiFi system concept targeting specific applications in which high speed wireless communication with high stability and security are required.
VI systems is responsible for the design, development and integration a VCSEL-array for a high-speed and high-power LiFi transmitter with imaging optics suitable for optical beam steering at 10 Gbit/s per user/designated area.

Extreme Energy-efficient Edge Cloud Hardware
E4C is an innovative concept for a scalable computer architecture, which consists of specialized computing nodes and a new type of data bus structure made up of optical and wireless communication links. It can be used in edge servers in virtualized 5G radio access networks and has an energy saving potential of up to 90 percent. In the project, the BMBF envisages an innovative solution for a core problem of 5G base stations, which in future would have to bear a considerable amount of energy for the distribution of computing load in virtualized radio access networks.
In this project VI Systems develops short-reach VCSEL-based interconnects operating at very high energy efficiency and a new compact packaging design that includes waveguide coupling for on-board interconnects.

Spatial Multiplexing in Optical Access Networks
In the "Spatial Multiplexing in Optical Access Networks (SAMOA-NET)" project, the transmission of data using spatial multiplexing over optical multi-core fibers in optical access networks is being developed. Multi-core fibers differ from today's glass fibers in that they have several cores in one fiber instead of one. A separate light signal can be fed into each of these cores, which leads to a multiplication of the possible light signals transmitted in parallel. Based on a jointly developed system concept, the essential components for data transmission are developed. This includes innovative VCSEL emitters, the multi-core fiber itself as well as flexible coupling and decoupling of light into the multi-core fiber. Finally, a system demonstrator will integrate the individual components and show the feasibility of different network architectures for an optical access network.

Photonic Transmitters for Optical Networks and Interconnects in energy-efficient datacenters, supercomputers and home based on VCSELs

To match the demand of the productivity of modern computing systems, which is growing three orders of magnitude per decade, the single interconnect channel bit data rate should double each 2.5 years and the number of channels per link increase 5-fold each 10 years. Until recently copper was the dominant interconnect technology ($120 billion). At higher frequencies the electromagnetic losses and cross-talk are drastically enhanced, and new technologies are required. Since 2012 60 thousands energy-efficient optical links made of multimode fibers (MMF) powered by Vertical cavity surface-emitting lasers (VCSELs) are used in a single rack of supercomputer. Due to its small size, circular surface emission pattern, low operating current and a narrow spectrum VCSELs result a low cost, energy-efficient optical modules. Bit date rates up to 14Gb/s over 100m are reached by the industry. Scaling of the device to higher speeds is challenging as the modulation bandwidth is increasing as a square root of the drive current, while the degradation accelerates exponentially. At higher pulse frequencies the transmission distance rapidly decreases with pulse broadening.

The way to match the speed upgrade is to apply advanced nanotechnology concepts.
- Properly designed ultrathin strained narrow gap insertions as gain medium drastically enhances the modulation bandwidth at the same current;
- Introducing of strained barriers preventing the nonequilibrium carriers’ escape from the gain region allows further improvement of the modulation bandwidth and reliability;
- Optical design by oxide-confined aperture induced diffraction allows single mode operation extending the transmission length.

VI-Systems GmbH was first to pioneer and ship VCSELs transmitters up to 40Gb/s over 100m, far beyond the limits at that time. 54Gb/s OOK transmission significantly exceeding 1 km of multimode fiber is achieved with pilot devices. VIS will commercialize its novel interconnect technology and extend it up to 50Gb/s per channel.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 666866.

ADDAPT (01.11.2013 – 30.04.2017)

Adaptive Data and Power Aware Transceivers for Optical Communications

Existing optical networks are driven by dynamic user demands but operate statically at their maximum performance and do not offer much adaptability. Thus the links are not energy-efficient. ADDAPT aims at the development and technology take-up of dynamic transceiver subsystems. By implementing performance and power adaptivity from system down to optical device, electrical circuit and transistor level, flexible energy-efficient optical transmission links are enabled which pave the way for massive reductions of CO2 emission and costs. Depending on the actual data load, the number of activated link paths and individual device parameters like bandwidth, clock rate, modulation format and gain are adapted to enable lowering the supply power. Several control types are investigated: cognitive adaption based on predetermined or time averaged loads and real-time adaption. Driven by control units including smart algorithms, the devices can be tuned from 8 to 56 Gb/s. Novel adaptive directly modulated lasers and photodetectors designed for near-field light coupling are developed to allow self-aligned low-cost waveguide assemblies with minimum optical power losses. Laser bandwidths beyond 30 GHz and power consumption can be traded off and controlled by driver circuits. Circuits such as amplifiers, drivers and clock data recoveries are designed in energy-efficient 14 nm CMOS and can be adjusted via current sources, dc/dc converters and switches. VIS designs epitaxial wafers and processing routs and provides epitaxial material for VCSEL and PINs. First single mode (>30db SMSR) VCSELs at >1.5mW having a modulation bandwidth >27GHz are demonstrated. Jointly with partners developing multi-rate 56Gb/sx1 and x4 electronics and packaging partners the project creates a path towards digital 56Gb/s transmission and next generation devices suitable for 100Gb/s at 50GBaud.

The project is funded by the European Commision through the Seventh Framework Programme (FP7). Project Nr. 619197.

NEWLED (01.11.2012 – 30.10.2016)

NEWLED (01.11.2012 – 30.10.2016)

Nanostructured Efficient White LEDs based on short period superlattices and quantum dots

NEWLED will develop high efficiency and high brightness monolithic and hybrid all-semiconductor WHITE light-emitting GaN-based diodes. NEWLED should also enhance the efficiency of bright red and yellow InGaAlP/AlGaAs LEDs by bandgap engineered superlattices. Novel light extraction approaches will target advanced directionality and colour adjustment. Values of 50 to 60% overall efficiency with a conversion of greater than 200 lm/W in the exploited warm white LEDs are targeted as well as the realization of a colour rendering index (CRI) of greater than 95. Advanced packaging will enable effective heat dissipation and light management. The devices will have immediate applications in automotive, industrial lighting and displays industries.

Widespread implementation would reduce global energy consumption by approximately 10% and reduce CO2 emissions by 3Bn tonnes with consequent economic and environmental benefits. Presently a strong improvement is realized for LEDs in the range of 580-610nm with strain-induced barrier engineering on substrates strongly misoriented from (100) direction is demosntrated. Injection lasing at 620nm is realized.

The project is funded by the European Commision FP7-ICT - Specific Programme "Cooperation": Information and communication technologies. Project Nr. 318388.

Compact Lasers with Increased Brightness

The task is to develop broad spectral range lasers suitable for frequency conversion over the complete blue-red spectral range. High power lasers and gain chips having a flat gain curve across 900-1260nm range are demonstrated at temperatures up to 150oC.  Lasing at 1.26 µm is realized on GaAs substrates. Novel approaches based on the tilted wave laser (TWL) concepts enabled lasers with ultrabroad waveguides >30 µm with duo-lobe emission pattern with each lobe having a full width at half maximum below 2o. Beam quality (M2) factor ~1.4 is achieved for a single mode making two-arm external resonator geometry easy. Focusing of the double beam with a single lens transforms the split beam into a Bessel like beam with further conversion to Gaussean. Coherence of the waveguide-copuled stripes up to 100 µm pitch sizes is demosntrated. Fequency converted green lasing and direct red laser emission in TWL lasers is demosntrated.
