Frequency pushing and pulling in semiconductor lasers subject to optical frequency comb injection

open access: yesResults in Engineering
We theoretically investigate the frequency shift of a free-running semiconductor laser when optically injected by an optical frequency comb. By numerical integration of the laser rate equations, we have identified two types of frequency shifts, frequency

Optomagnonic frequency combs

open access: yesPhotonics Research, 2022
Optical frequency combs are fundamentally important in precision measurement physics, bringing unprecedented capabilities of measurements for time keeping, metrology, and spectroscopy. In this work, we investigate theoretically the formation of a form of frequency combs in cavity optomagnonics, in which a ferrimagnetic insulator sphere supports optical

Broadband optical frequency comb generation based on single electro-absorption modulation driven by radio frequency coupled signals

open access: yesFrontiers of Optoelectronics, 2022
Broadband optical frequency comb (OFC) generation based on a single electro-absorption modulator (EAM) is proposed. The EAM is driven by a radio frequency (RF) multi-frequency signal generated by a multiplication coupler composed of an electrical power ...

Simultaneous suppression of time and energy uncertainties in a single-photon frequency comb state

open access: yes, 2014
A single photon prepared in a time-energy state described by a frequency comb combines the extreme precision of energy defined by a single tooth of the comb with a high sensitivity to small shifts in time defined by the narrowness of a single pulse in ...

X-ray frequency combs from optically controlled resonance fluorescence

open access: yes, 2013
An x-ray pulse-shaping scheme is put forward for imprinting an optical frequency comb onto the radiation emitted on a driven x-ray transition, thus producing an x-ray frequency comb.

Broadband electro-optic frequency comb generation in an integrated microring resonator

open access: yes, 2018
Optical frequency combs consist of equally spaced discrete optical frequency components and are essential tools for optical communications and for precision metrology, timing and spectroscopy. To date, wide-spanning combs are most often generated by mode-

Full phase stabilization of a Yb:fiber femtosecond frequency comb via high-bandwidth transducers [PDF]

open access: yes, 2012
We present full phase stabilization of an amplified Yb:fiber femtosecond frequency comb using an intra-cavity electro-optic modulator and an acousto-optic modulator. These transducers provide high servo bandwidths of 580 kHz and 250 kHz for frep and fceo,
