Bottom-illuminated, high speed avalanche photodiode chip with a tapered coplanar transmission line and an integrated backside lens. The APD is optimized for single-mode Gigabit Passive Optical Networks (GPON) and 10 Gb/s SONET/SDH telecom applications. A key feature of this innovative APD is low excess noise, enabling receiver sensitivities of -29 dBm for 10 Gb/s NRZ signals when used with an appropriate TIA.
The integrated backside lens focuses the incoming light beam on the topside detecting area, enabling an easy and efficient optical coupling.
