Light Channel 5 Gb/s Optoelectronic TDM (Time Division Multiplexing)

Abstract

An 8:1, 5 Gb/s, time division multiplexer has been implemented using optoelectronic or metal-semiconductor-metal switches for sampling. The device was fabricated on InP and the switches activated via optical fiber delay lines by pulses from a GaA1As laser diode array. This device concept is applicable to chip and to board level computing multiplexing. Time division multiplexing (TDM) , serializing parallel data for high speed transmission, is an important element in most concepts and implementations in computer networking as well as other areas of communications. An optoelectronic TDM (OE-TDM) approach(1) is advantageous in speed, power, and signal-control isolation. It was conceived initially to offer serial transmission off VLSI chips and recently has shown promise as a stand alone multiplexing technique. We report an improved multiplexer in InP giving an 8:1 multiplex ratio, a 26 dB signal-to-noise ratio, and a 5 Gb/s serial data rate while using a realistic parallel data level of 2 volts instead of the earlier 15 V(1).
