A gigabit-rate five-highway GaAs OE-LSI chipset for high-speed optical interconnections between modules or VLSIs

A gigabit-rate five highway interface GaAs optoelectronic LSI chipset has been fabricated for the 0.85 mu m wavelength range optical interconnections between modules or VLSIs. The optical sender consists of a high-speed laser driver array LSI having 2 Gb/s maximum operation speed and a tiny laser array. The optical receiver in a GsAs high-speed optical receiver array LSI with a monolithically integrated metal-semiconductor-metal (MSM) photodetector, a high-speed preamplifier, and a decision circuit that has a maximum operation speed of 1.8 Gb/s. The receiver LSI is provided with a new bit-synchronizing circuit and an automatic threshold determination circuit.<
