We discuss, both by simulation and experiment, the design of balanced differential phase-shift keying receivers. We study detector amplitude imbalance and phase imbalance, interferometer delay mismatch, interferometer extinction, and laser frequency offset. The most critical impairment in a practical receiver is found to be a mismatch between laser frequency and interferometer phase, which directly impacts the interference quality.
