Abstract

The design of high-speed, high responsivity PIN optical detectors for fiber optic telecommunication test equipment requires a very careful trade-off between lateral and vertical active area dimensions. A thin absorption layer (i-layer) leads to high bandwidth at the expense of responsivity. A large-area device improves light coupling efficiency from a fiber, but reduces the bandwidth. In addition, packaging constraints must be considered. Our approach attempts to optimize the end-system performance by incorporating an integral micro-lens which increases the effective light collection area; a double-pass illumination strategy that increases the bandwidth without sacrificing responsivity; and a micro-flip-chip die attachment technology that minimizes parasitic capacitance and inductance. An optical receiver composed of a GaAs MODFET-based transimpedance amplifier and a flip-chip PIN photodector exhibited a bandwidth of 7.2 GHz with an optical-to-electrical conversion gain of 560 V/W.
