Original practical and theoretical results are presented for heterodyne detection of optical digital pulse-position modulation (λ = 1.523 μm) employing suboptimal filtering. The measured sensitivity was –62.7 dBm when operating with a 20 ns slot width and 16 data-pulse positions. This represents an improvement of 16.8 dB over an equivalent suboptimal direct detection digital pulse-position modulation system. With –18 dBm of local oscillator power, the sensitivity was within 8.6 dB of the shot-noise limit.
