Paper Abstract

We demonstrate the high-speed operation of a wavelength- division-multiplexed optical interconnect, which is implemented by multiplexing the optical data from a multiple wavelength vertical-cavity surface-emitting laser (VCSEL) array into a single optical fiber, and demultiplexing the composite data stream using an array of resonance-enhanced photodetectors (REPD) with matching resonance wavelengths. By using VCSELs and REPDs with a quasi-planar oxide- confinement design for improved high speed performance, and using strained InGaAs/GaAs quantum wells to achieve a better trade-off between optical responsivity and wavelength selectivity, WDM operation has ben demonstrated under 1.25 Gb/s data modulation, with an optical crosstalk rejection ratio of better than -10 dB for wavelength channels that are spaced approximately 4 nm apart. The transmission performance of a single-channel, 1.0 Gb/s fiberoptic link with a 1 km span is characterized, achieving a BER equals 10-12 at a received optical signal level of -16.7 dBm. In addition, the effect of optical crosstalk from a neighboring wavelength channel, as well as the power penalty for thermally-induced wavelength de-tuning between the VCSEL and REPD have been determined.
