Optoelectronic components: VCSELs and PDs

VI Systems leverages its industry leading optical design technology to offer a wide a portfolio of Vertical-Cavity Surface-Emitting Laser (VCSEL) and Photo-Diode (PIN PD) components for the standard data rates of 28 Gbps, 56 Gbps and 112 Gbps data rates. For inquiries contact us at: sales@v-i-systems.de

VCSEL, Vertical-cavity surface-emitting laser (VCSEL) and PD, photodiode (PD) — VI Systems single optoelectronic chips feature a footprint of 250x250 µm

VCSELs and PDs are also available as fiber-coupled modules and as testboards in combination with VI System's 56 Gbit/s NRZ VCSEL Driver and Transimpedance amplifier (TIA)

Ultra High-Speed VCSELs: up to 112 Gbit/s VCSELs

VI System's ultra high-speed VCSELs offer up to 30 GHz bandwidth and they are suitable for 112 Gbit/s PAM-4 data transmission. With offline equalization data transmission rates up to 200 Gbit/s PAM-4 and 224 Gbit/s DMT were demonstrated. The VCSELs are available in the whole Short Wavelength Division Multiplexing (SWDM) range of 840 - 960 nm in two design versions: standard VCSEL and multi-aperture mini-array. The mini-array versions feature a narrow far-field and spectral width (~0.1 nm) enabling efficient fiber coupling and increased transmission reach through Multi-Mode Fiber (MMF) through reduction of chromatic dispersion.
