Abstract :
The development of waveguide avalanche photodiodes with a very thin 0.1 μm multiplication layer for use in high-speed, high-sensitivity, low-voltage-operation receivers is presented. A η=76% a GB product of 180 GHz. And a breakdown voltage Vb of 15 V were obtained. The 10 Gbit/s bit error rate measurement showed a sensitivity of -28 dBm (BER 10-9, PRBS 223-1), which is the highest sensitivity yet reported for APD receivers
