Abstract
The recent commercial availability of broadband linear-phase operational amplifiers has allowed a new high-bit-rate transimpedance optical receiver design to be realised. This design allows the convenient optimisation of the receiver frequency response for minimum noise and intersymbol interference. Practical sensitivities of −49.3 dBm (70% QE) at 140 Mbit/s and 1.52 μm have been routinely achieved using packaged components and 30 μm-diameter Ge p+n APDs.Keywords
