Ultrafast Electro-optic Laser

NIST Inventors
Scott Papp , Scott Diddams and David Carlson
patent description Our invention is for an ultrafast light source that produces femtosecond pulses with sub-cycle timing jitter using electro-optic switching of a continuous-wave (cw) laser. The apparatus is composed of the following key elements: 1) an electro-optic (EO) frequency comb, 2) a

Optical Reference Cavity

NIST Inventors
Franklyn Quinlan , Scott Diddams and Andrew Ludlow
Patent Description We have demonstrated an easy-to-manufacture 25-mm-long ultra-stable optical reference cavity geared toward transportable photonic microwave generation systems and mobile optical atomic clock applications. The cavity can be rigidly held in a way that is first-order insensitive to

METHODS AND APPARATUS FOR GENERATING MID-INFRARED FREQUENCY COMBS

NIST Inventors
Scott Diddams , Scott Papp , Abijith Kowligy and Alexander Lind
patent description We present a new approach to generating a coherent comb of infrared frequencies utilizing intra­ pulse difference frequency generation. The central claims of this invention are: A simple technique to generate few-cycle pulses derived from an amplified Er:fiber mode­ locked laser

METHOD AND PROCESS FOR TANTALA INTEGRATED NONLINEAR PHOTONICS

NIST Inventors
Scott Papp , David Carlson and Kartik Srinivasan
patent description The invention is a method and process to create integrated nonlinear photonics, using the material tantalum pentoxide (Ta2O5, also known as tantala). Our innovation is use of the tantala material and demonstration of the properties needed to support nonlinear processes like
