Datasheet: Deschutes BSI™ Backside-Illuminated Reduced-Noise Avalanche Photodiode (R APD) on Submount: VFC 1000 Series

The R APD is custom-engineered for reduced excess noise, which allows this APD to achieve higher sensitivity, better signal to noise (STN) performance, and lower bit error rates (BERs) than conventional telecom APDs. In comparison to conventional telecom InGaAs/InP APDs, which have an excess noise characterized by k_eff = 0.4, Voxtel's Deschutes BSI™ InGaAs/InAlAs R APDs, characterized by k_eff < 0.2, have 40% less excess noise, which allows for lower shot noise over the operating gain of the R APD. The increased sensitivity of the R APD improves system cost, size, weight, and power (CSWAP) by reducing demands on computation and laser power while increasing standoff range.
