OEwaves to Develop EMP-Immune Receiver Under DARPA Contract

PASADENA, Calif., Sept. 13, 2010 — Microwave photonic products and solutions provider OEwaves Inc. received recently a Phase II contract from DARPA to develop an electro-magnetic pulse (EMP) immune all-dielectric RF photonic receiver.

Issued under DARPA’s Electro-Magnetic Pulse Tolerant Microwave Receiver Front End (EMPiRE) program, the company’s novel approach will achieve the performance goals of the program and result in delivery of all-dielectric photonic-assisted radio front-end with a compact, scalable design. The receiver development will be based on its platform technology of crystalline whispering gallery mode (WGM) resonator.

Occurring in circularly symmetric dielectrics structures, the WGM optical resonances are available in sizes ranging from tens of microns to a few mm, which trap light in a small volume.

DAPRA’s EMPiRE program seeks to develop a microwave receiver front-end capability that will survive and operate short pulses of high energy while maintaining high sensitivity, bandwidth and dynamic range.

“We are extremely excited to be selected as a Phase II performer in this challenging program,” said Lute Maleki, president and CEO. “OEwaves microwave photonics success toward meeting the requirements of EMPiRE in Phase I will be extended to address the more challenging goals of Phase II.”

Glossary

bandwidth: The range of frequencies over which a particular instrument is designed to function within specified limits. See also fiber bandwidth.
dielectric: Exhibiting the characteristic of materials that are electrical insulators or in which an electric field can be sustained with a minimum dispersion of power. They exhibit nonlinear properties, such as anisotropy of conductivity or polarization, or saturation phenomena.
receiver: A detector and signal demodulator used in optical communications systems to receive a signal and often to translate it into an electronic signal.
sensitivity: In a radiation detector, the ratio of the output to the input signal.
whispering gallery mode: Whispering gallery mode (WGM) refers to a phenomenon in wave physics, particularly in optics, where waves, such as light or sound waves, are trapped and circulate along the periphery of a curved surface. The term "whispering gallery" is derived from the acoustic behavior observed in certain architectural structures, like domes or circular galleries, where whispers or sounds made at one point can be heard clearly at another distant point due to multiple reflections along the curved surface.
