Deschutes BSI™ Backside-Illuminated Reduced-Noise Avalanche Photodiode (R APD) On Submount: VFC‑1000 Series
Source: Voxtel, Inc.
Voxtel's VFC‑1000 series of Deschutes BSI™ backside-illuminated R‑APDs provide both higher responsivity and lower capacitance than competing frontside-illuminated APDs. They are available with active areas 30, 75, or 200 µm in diameter, on ceramic submounts.

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 keff = 0.4, Voxtel's Deschutes BSI™ InGaAs/InAlAs R‑APDs, characterized by keff < 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.
