  • NIH Awards Vixar VCSEL Contract
Sep 2012
PLYMOUTH, Minn., Sept.26, 2012 — Optoelectronic components and subassemblies supplier Vixar will demonstrate the feasibility of a vertical-cavity surface-emitting laser (VCSEL) with a tuning range of 35 nm under a new contract from the National Institutes of Health.

Vixar is collaborating with Beckman Laser Institute at the University of California, Irvine, under the Small Business Innovation Research contract to develop a swept near-infrared light source that enables a portable hyperspectral tomographic functional optical imager. The initial prototype device will be inserted into a handheld diffuse optical spectroscopic system to monitor and predict chemotherapy response in breast cancer treatment.

Phase II of the project will optimize the device’s performance and extend it to the full range of wavelengths. It will be implemented into a handheld imager to demonstrate full imaging functionality.

The optical source is expected to enable improved image signal to noise, contrast and imaging depth.

Vixar, an early-stage startup, was founded in 2005 by Drs. Klein Johnson and Mary Hibbs-Brenner, both of whom were instrumental in establishing the VCSEL business at Honeywell Corp.

A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
