<title>Optical receiver for IM-DD systems operating at 2.488 Gbit/s</title>

Abstract

In this paper we present the design approach and measurements of an optical receiver suited for IM-DD systems operating up to 2.5 Gbit/s bit-rate. The receiver is composed by a Ga-As MMIC transimpedance amplifier and a commercially available pin photodiode. The MMIC amplifier has been fabricated and it has been measured on wafer, showing a -3 dB cut-off frequency of 2.6 GHz, stability and low sensitivity to bias variations.
