March 15, 2010 — Beaverton, Ore. — Voxtel has announced the release of an avalanche photodiode (APD) receiver with 1-gigahertz bandwidth and a large 200-μm-diameter optical area. The company believes it to be the highest-bandwidth large-area NIR APD receiver, which makes it optimal for a broad range of laser rangefinders and laser designators, and for applications in free-space optical communications, optical instrumentation, and LADAR/LIDAR.
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.
June 11, 2009 — A recent article in Nature News notes that the market for quantum dots and nanocrystal material is poised for a boom in the coming four years. Key to this expansion will be reductions in price, made possible by improved manufacturing techniques. Voxtel is at the forefront in this area:

Model REP-1XJ0A Siletz Receivers are the Most Sensitive High-Speed NIR Optical Receiver Available
May 11, 2009 – Beaverton, Oregon – Voxtel has announced the release of its ‘Siletz’ series of APD receivers, responding to the demand for eye-safe and highly sensitive optical communications, LIDAR, and LADAR in the near infrared (NIR) spectrum. Voxtel’s Siletz APD receiver optical subassembly provides sensitivity 2 to 4 dBm improved over any other APD receiver currently available on the market covering the 950–1700 nm spectral range, and operates at frequencies up to 2.7 GHz.
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.
October 30, 2008 – Durham, N.C. – Nextreme Thermal Solutions, the leader in microscale thermal and power management products for the electronics industry, today announced that Voxtel, Inc., a leading developer of sophisticated detectors and electrooptical imaging systems, has integrated Nextreme’s OptoCooler UPF4 thermoelectric cooler into Voxtel’s VDHAX line of hermetically packaged avalanche photodiode (APD) receivers.
May 6, 2008 – Eugene, Ore. – Today, Voxtel, Inc. announces it has completed the negotiation of a long-term lease to occupy private development laboratories at the ONAMI (Oregon Nanoscience and Microtechnologies Institute) Lorry I. Lokey Laboratories located at the University of Oregon’s Eugene campus.
The Integrative Science Center at the Lorry I. Lokey Laboratories represents world-class facilities and infrastructure for scientific research. It provides Voxtel access to one of the world’s largest and deepest collections of state-of-the-art equipment and technologies and provides Voxtel with a significant time and infrastructure advantage in the global race for innovation.
For Immediate Release
March 6, 2008 – Beaverton, Ore. – Voxtel, Inc. plans to announce its entry into the business of manufacturing “green” semiconductor and metal-oxide nanocrystals for a wide variety of customer applications, including: photovoltaic solar cells, electro-luminescent lighting, anti-counterfeiting taggants, and security inks. Voxtel’s focus is on the synthesis and scaling-to-manufacture of “green”, environmentally friendly semiconductors and semiconductor core-shell nanocrystals.
February 27, 2008 – Beaverton, Ore. – Voxtel, a leader in innovative low-light detectors and instruments, announces today the release of its newest product family of Solid-State Silicon Photomultipliers (SiPMs).
The performance of these VIC-series SiPMs is superior to that of conventional photomultiplier tubes (PMTs), with the compactness and added benefits of semiconductor detectors, and high gain (~106) allowing
the detection of single photons.
December 3, 2007 – Beaverton, Ore. – Voxtel, Inc., in conjunction with Oregon Nanotechnology and Materials Institute (ONAMI), announces today that the U.S. Department of Energy (DOE), under its Solar Energy Technologies Program, has awarded Voxtel a $0.8 million program to advance a fundamentally new class of composite nanocrystal (quantum dot) photovoltaic (PV) solar cells using environmentally friendly materials.
June 3, 2007 – Beaverton, Ore. – Voxtel, Inc. announces today that the Department of Energy (DOE) has awarded Voxtel four Small Business Innovation Research (SBIR) program contracts to develop high-performance optical detectors that will help pave the way for nanotechnology innovations. The combined $400k contract values have options that could extend their value to $3M. The research leading to Voxtel’s awards was enabled by its collaboration with the Oregon Nanoscience and Microtechnologies Institute (ONAMI) in Eugene, Oregon.
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.
May 15, 2006 – Beaverton, Ore. – Voxtel, Inc., provider of optoelectronic devices using novel semiconductor architectures and nanotechnology-engineered materials, has introduced a suite of avalanche photodiodes (APDs) delivering the best possible sensitivity for high-bandwidth applications — reducing the excess avalanche noise by more than a factor of three over contemporary APDs, and thus enabling longer detection ranges and higher sensitivity for a variety of military, medical, and scientific applications.

Ladar systems are used to detect the fine detail of remote objects that are needed for distance, shape, and pattern perception at very long distances. Download PDF.
July 3, 2003 – Portland, Ore. – Voxtel, Inc. today announced that it has received seven Small Business Innovative Research (SBIR) contracts totaling $490,000. The contract awards are to pursue research and development of highly sensitive infrared, laser radar (ladar), and electro-optical systems. The contract is sponsored by the Missile Defense Agency’s Small Business Innovation Research (SBIR) Program and managed by the U.S. Army Space and Missile Defense Command (Huntsville, Ala.) and the Air Force Research Laboratory (Wright-Patterson AFB, Ohio).
