Abstract

A wavelength-division multiplexed (WDM) optical interconnect operating at 1 Gb/s per channel is demonstrated using quasi-planar multiwavelength InGaAs (920 nm) vertical-cavity surface-emitting laser (VCSEL) and resonance-enhanced photodetector (REPD) arrays with closely matching wavelengths. The transmission performance of a single-channel 1.0-Gb/s fiberoptic link with a 1-km span is characterized, achieving a BER=10/sup -12/ at a received optical signal level of -16.7 dBm. In addition, the effect of optical crosstalk from a neighboring wavelength channel (4 nm apart) as well as the power penalty for thermally induced wavelength detuning between the VCSEL and REPD have been determined.
