Direct generation of optical frequency combs in χ(2) nonlinear cavities

Nanophotonics, 2016
Quadratic nonlinear processes are currently exploited for frequency comb transfer and extension from the visible and near infrared regions to other spectral ranges where direct comb generation cannot be accomplished.

Highly multimode memory in a crystal

, 2010
We experimentally demonstrate the storage of 1060 temporal modes onto a thulium-doped crystal using an atomic frequency comb (AFC). The comb covers 0.93 GHz defining the storage bandwidth.

Doppler cooling with coherent trains of laser pulses and tunable "velocity comb"

, 2011
We explore the possibility of decelerating and Doppler cooling of an ensemble of two-level atoms by a coherent train of short, non-overlapping laser pulses.

Efficient microresonator frequency combs

eLight
AbstractThe rapid development of optical frequency combs from their table-top origins towards chip-scale platforms has opened up exciting possibilities for comb functionalities outside laboratories. Enhanced nonlinear processes in microresonators have emerged as a mainstream comb-generating mechanism with compelling advantages in size, weight, and ...

Optical Lattice Trap for Kerr Solitons

, 2017
We show theoretically and numerically that dichromatic pumping of a nonlinear microresonator by two continuous wave coherent optical pumps creates an optical lattice trap that results in the localization of intra-cavity Kerr solitons with soliton ...

Miniature Optical Atomic Clock: Stabilization of a Kerr Comb Oscillator [PDF]

, 2013
Mechanical clocks consist of a pendulum and a clockwork that translates the pendulum period to displayed time. The most advanced clocks utilize optical transitions in atoms in place of the pendulum and an optical frequency comb generated by a femtosecond

A monolithic MQW InP/InGaAsP-based comb generator [PDF]

, 2006
We report a monolithic optical frequency comb generator using quaternary/quaternary multiple quantum well InV/InGaAsP material as phase modulator and gain medium in a Frequency Modulated (FM) laser design. The modulation was generated by quantum confined

Frequency comb generation threshold via second-harmonic excitation in χ(2) optical microresonators

APL Photonics, 2020
We investigate the threshold of χ(2) frequency comb generation in lithium niobate whispering gallery microresonators theoretically and experimentally. When generating a frequency comb via second-harmonic excitation, also commonly known as second-harmonic

Optical frequency comb generation from a monolithic microresonator

, 2007
Optical frequency combs provide equidistant frequency markers in the infrared, visible and ultra-violet and can link an unknown optical frequency to a radio or microwave frequency reference.
