Engineering Samples

Sample image only. Actual product may vary.

Product Description
These compact and very high modulation rate top-emitting GaAs-based vertical cavity surface emitting
laser (VCSEL) chips are available as engineering samples for use in the development and evaluation of
optical interconnections, optical backplanes and integrated waveguides, and next-generation optical
data communications systems. The VCSELs are contacted on the top-surface individually using groundsource-ground (GSG) microprobes or wire bonds.
Optical aperture: ~5-7µm

Features· Up to 112 Gbit/s (PAM-4 modulation)· Single chip size 250 x 250 µm· Suitable for wire bonding

Applications· 200G / 400G in SWDM
· Proprietary optical interconnects· Active Optical Cables (AOC)

LIV Characteristics

Optical Spectrum

Transmitter: SHF BPG 12104A. Receiver: Tektronix DSA8300 w. 80C15 Optical Sampling Module.
Eye diagrams show intrinsic performance of the chip. No equalization or signal processing was applied.
If the eye-diagram is open at 50Gbaud NRZ without equalization, one can expect good 100Gbit/s PAM4
transmission quality if appropriate PAM driver or/and pre-equalized signal is applied.

Qualification Notification
The VM10-940-GSG-C1 has been tested to meet specifications outlined in this data sheet at room
temperature. However, it has not undergone full qualification testing or characterization and therefore
may not meet the performance specifications over all extremes.
