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

Hub and Spoke System for Detecting and Locating Gas Leaks

NIST Inventors

Greg Rieker , Ian Coddington , Kuldeep Prasad and Anna Karion

A system for detecting gas leaks and determining their location and size. A data gathering portion of the system utilizes a hub and spoke configuration to collect path-integrated spectroscopic data over multiple open paths around an area. A processing portion of the system applies a high-resolution
