The PA006700 from Oclaro is an Indium Phosphide (InP) based Avalanche Photodiode (APD) chip designed for high-performance telecoms receiver applications up to 11.3Gb/s. The optical signal is received via top illumination of the central active region through a ring-shaped contact which provides a 30µm aperture.
A reverse electrical bias is applied across the active region by the P (anode) and N (cathode) contacts. The circular P bond pad has a diameter of 70µm suitable for wire bonding. The APD is suitable for operation at up to 11.3Gb/s at a multiplication gain factor between M3 and M10. The chip is ideal for long-haul networks, 10G PON, single mode datacom, and telecom applications.
