Miniaturised, hybrid, 500 Mb/s optical receiver package for data-link applications
Abstract
Optical fibers could be used for a high-capacity link (several hundred Mb/s) to interconnect many digital terminals. The paper describes the design features and capabilities of a simple miniaturized hybrid optical receiver package built to operate at 500 Mb/s in the NRZ format. The front end consists of an avalanche photodiode followed by an operational amplifier and a decision circuit. The regeneration circuit is composed of a clocked master-slave flip-flop circuit requiring a phased clock of the order of 100 mV peak-peak. All the components are mounted on a gold ceramic substrate where the interconnections are etched using standard photolithographic masking techniques. A GaAs laser driven by a FaAs FET is used as the transmitter and data in NRZ format are transmitted at different bit rates. The receiver exhibits a sensitivity of -23 dBm which is adequate for data link applications.
