Abstract

In .53Ga 47As/InP photodiodes and hybrid InP-InGaAsP APDs designed for long wavelength optical fiber communication are discussed. The photodiodes have rise and fall times <0.5 nsec, dark currents in the nanoamp range, subpicofarad capacitance, and high quantum efficiency. The APDs have a long wavelength cutoff of -1.25 μm, have negligible dark current (ID <6 nA at a gain of M = 30), and have an excess noise factor F given by F/M = 0.42 ± 0.10 = const for 5 ≤M≤ 5 35. The detectors are packaged in sealed micro-window packages that allow nearly 100% coupling efficiency to optical fibers with core diameters up to 100 pm (NA 0.30).
