Self-referencing Nonlinear Frequency Converting Photonic Waveguide and Self-referencing Nonlinear Frequency Conversion

NIST Inventors

Jeff Chiles and Ian Coddington

The invention is an optical frequency comb sub-system that utilizes nano-scale photonic waveguides made of aluminum gallium arsenide (AlGaAs) to perform the nonlinear frequency conversion required to realize f-to-2f self-referencing. Thanks to the high optical nonlinearities, this task can be

Quantum Waveguide Infrared Photodetector

A novel quantum well infrared photodetector (QWIP) is proposed, which provides an unprecedented signal-to-noise ratio compared any other infrared detector. The key feature is the ability to inject light in the absorbing regions in the plane of the detector material layers, rather than surface normal

Quantum Waveguide Infrared Photodetector

Systems and Methods for Efficient Optical Frequency Conversion with Integrated Optical Systems

NIST Inventors

Jeff Chiles

Various embodiments of the present technology provide a novel architecture for optical frequency conversion in a waveguide which can be applied to any suitable nonlinear waveguide material and any wavelength. In accordance with some embodiments, phase-matched bends can be used to increase the
