WAVELENGTH MULTIPLEXING AND DEMULTIPLEXING USING MULTIWAVELENGTH VCSEL AND RESONANCE-ENHANCED PHOTODETECTOR ARRAYS

A novel wavelength-division-multiplexed optical interconnect is demons trated in which optical data from a monolithic wavelength-chirped VCSE L array is multiplexed onto a single fiber, and then demultiplexed usi ng an array of wavelength-selective resonance-enhanced photodetectors with closely matched resonance wavelengths. This is demonstrated under both de and 125-Mb/s data modulation, achieving an optical crosstalk rejection ratio of similar to -10 dB (-7.5 dB) for channels that are s paced 6 nm (4 nm) apart.
