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

NIST Inventors

Jeff Chiles , Ian Coddington and Eric Stanton

patent description The unique frequency accuracy of a frequency comb stems from “f-to-2f” self-referencing where an optical octave is generated and the low frequency edge of that octave is doubled and compared to the high frequency end to measure the carrier envelope offset frequency, the key piece

QUANTUM WAVEGUIDE INFRARED PHOTODETECTOR

NIST Inventors

Eric Stanton

patent description The QWIP was first demonstrated in 1987 [1] and consistent research since then has improved the QWIP detection efficiency, but only for surface normal detection. Development of the QWIP was originally intended for infrared focal plane arrays suitable for infrared cameras. One

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

NIST Inventors

Eric Stanton and Jeff Chiles

Patent Description A novel architecture for optical frequency conversion in a waveguide is proposed, which increases the conversion efficiency compared to existing architectures. It consists of several straight sections of phase-matched nonlinear optical waveguides linked by dispersion-engineered
