Paper Abstract

The current trend of increasing data rates for fiber optics communications systems has created a demand for high-speed lightwave measurement instrumentation. For time domain measurements, a key element is a lightwave receiver for converting the optical signal to an electrical signal which can then be analyzed by conventional methods. The requirements for a high-speed lightwave receiver include DC-coupling, sufficient bandwidth to accurately reproduce the optical signal, frequency response flatness, sensitivity for measuring low signal levels, and linearity to avoid signal distortion. A receiver has been designed within Hewlett-Packard to meet these requirements for data rates up to 2.5 Gb/s. The receiver design consists of a high-bandwidth InP/InGaAs/InP p-i-n photodiode and a GaAs transimpedance amplifier. The photodiode has a bandwidth of 32 GHz with a responsivity greater than 0.5 A/W. The transimpedance amplifier has a gain of 600 ohms, flat frequency response, and a bandwidth of over 7 GHz. The combination results in a DC-coupled receiver with a bandwidth of over 4 GHz and a conversion gain of 330 V/W. The receiver provides accurate measurement capability for optical transmitters for both SONET and fibre channel communications systems.
