VI Systems offers the T80-DRV-TB evaluation board with a new generation of single channel laser driver for non-return-to-zero (NRZ) modulation at bit data rates of up to 80 Gbit/s  “ON-OFF” keying (OOK) enabling low latency optical data transmission. The test board features two electrical 1.85 mm high-frequency connectors for differential signal input. The laser driver …

VI Systems publishes the results of a novel type of diode laser which is emitting in the yellow-orange spectral range (599 – 605 nm wavelength). Target applications are medical use, industrial spectroscopic analysis and ultra-high precision optical atomic clock.   VI Systems published the results of prototype manufacturing of solid state diode laser. The lasing in …

VI Systems offers a new set of ultrahigh-speed multi-rate driver and amplifier chips which target applications in data communications at low latency RZ (return-to-zero) and NRZ (non-return-to-zero optical) modulation at bit data rates up to and beyond 50 Gbit/s and in time-of-flight (ToF) sensing at ultimate spatial resolution. These driver and limiting amplifier integrated circuits …

VI Systems demonstrated successfully with their newly developed fiber coupled ultrahigh-speed testboard set with transmission results of > 50 Gbit/s with NRZ modulation. The testboard includes a new generation of 56G VCSEL driver respectively a 56G limiting amplifier chip. The fiber coupling is arrange through active alignment of a PRIZM connector with a FC/PC optic …
