Abstract :
A planar-type InGaAs/InP-heterostructure APD with an InGaAsP buffer layer was made by using a VPE technique. To avoid the edge breakdown, a guard-ring structure was employed. The average received optical power for a 10¿9 error rate at 280 Mbit/s was as low as ¿43 dBm, which corresponded to 2 and 7 dB improvements over a Ge-APD at 1.52 and 1.59 ¿m, respectively.
