The Lumentum APD chip is an indium phosphide (InP) based device designed for high performance telecoms receiver applications up to 11.3 Gbps. The optical signal is received via top illumination of the central active region through a ring shaped contact which provides a 30 μm 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 70 microns suitable for wire bonding. 

The APD is suitable for operation at up to 11.3 Gbps at a multiplication gain factor between M3 and M10. 

Performance is checked by on wafer testing comprising DC, CV and AC test measurements. 

Proven reliability of <1FIT derived from over 40 billion field hours. 

Telcordia ESD rating: minimum 500 V human body model.
