Abstract:

Hybrid-structure InP-InGaAsP APDs have been fabricated which have negligible dark current I sub D 6 nA at M 30. The excess noise factor F, for a hole-initiated avalanche, has been determined to be FM 0.42 or - 0.10 for 5 or M or 35. Conventional structure high-bandgap 1.27 eV InGaAsP APDs have been fabricated. These resemble low-leakage InP APDs rather than the high-leakage low-bandgap 1.00 eV InGaAsP APDs. Low-noise bipolar transimpedance preamps have been designed and fabricated. These have bandwidths out to 500 MHz for R sub f 1 K omega. The sensitivity of the best hybrid APDs used with these preamps is estimated to be -46.6 dBm for a 100 Mbitsec, 10 to the minus 9th power bit error rate system, operating at a wavelength of 1.1 microns.
