February 15, 2010 — Beaverton, Ore. — Voxtel has announced the release of its latest product line, the Deschutes BSI™ series of back-side-illuminated APDs.
The Deschutes BSI™ APDs are available on ceramic submounts, with a co-mounted temperature sensor. Compared to front-side-illuminated APDs, they offer superior responsivity and lower capacitance. Deschutes BSI™ APDs offer typical responsivity greater than 1.0 A/W at 1550 nm and 0.73 A/W at 1064 nm, and operating gain from 3 to 20. These InGaAs/InAlAs APDs have been custom-designed for low excess noise, with a design exploiting the non-local behavior of impact ionization. The resulting APDs have 40% less excess noise than conventional telecom InGaAs/InP APDs, which makes them ideal for optical communications, laser radar (LADAR) and LIDAR, and laser rangefinding/designating applications.

Single-carrier multiplication APDs offer higher gain and lower noise than conventional avalanche photodiodes
February 16, 2009 – Beaverton, Oregon – Voxtel Incorporated announces a new class of near-infrared photodetectors: single carrier multiplication APDs (SCM-APDs). SCM-APDs are nanostructured indium gallium arsenide/indium aluminum arsenide (InGaAs/ InAlAs) devices that have been designed to overcome the limitations of conventional avalanche photodiodes (APDs) in the 0.9 to 1.6 micron spectral region, including the eye-safe range beyond 1.3 microns. These new photodetectors exceed the capabilities of APDs in both gain and noise performance. With their high gain and low noise, combined with high quantum efficiency, Voxtel’s SCM-APDs are ideal for low-light-level detection, or any other applications that call for industry-leading sensitivity in the near-infrared spectral band.

May 15, 2007 – Beaverton, Ore. – Voxtel has demonstrated a new linear-mode APD design that combines the noise characteristics of silicon with the near-infrared sensitivity of InGaAs. Unlike approaches in which a silicon multiplier is fused to a III-V absorber, Voxtel’s monolithic APD wafers are grown epitaxially on InP substrates, using only lattice-matched III-V alloys. Conventional III-V APDs that use InGaAs absorbers typically have bulk InP multiplication layers, characterized by an ionization coefficient ratio of k~0.4.
