Microwave Impedance Matching of Photodiodes for High Speed Optical Communications Systems.

Abstract

The performance of optical communications systems can be influenced by the mismatch between the low impedance laser source and the high impedance generator. A procedure is described here for matching a laser diode to a 50 ohm generator by means of a lossless equalizer network. The equalizer network is realized in the form of a microstrip adaptation of a ladder network consisting of inductor and capacitor equivalents. The mathematical model predicts 50-70% improvement in transducer power gain. Experimental results confirm this.
