In this study, we presented flat-topped coherent supercontinuum lasers with tunable
repetition rates and programmable spectral bandwidths. Supercontinuum sources with ultra …

Microresonator frequency combs (micro-combs) are very promising as ultra-compact
broadband sources for microwave photonic applications. Conversely, microwave photonic …

Optical frequency combs generated by quantum cascade lasers have recently been
demonstrated in the mid and far infrared, but a detailed analysis of the possibility of a fine …

The present theoretical work studies optical frequency combs (OFCs) associated with both
linear polarizations of a gain switching vertical-cavity surface-emitting laser (VCSEL) subject …

Direct digital synthesis in concert with an electro-optic phase modulator was employed to
generate optical frequency combs with tooth spacings as low as 100 Hz. These combs were …

We propose a new approach to the generation of acoustic frequency combs (AFC)—signals
with spectra containing equidistant coherent peaks. AFCs are essential for a number of …

We present experiments and numerical simulations of optical frequency combs generated
by gain-switching a single mode laser diode when subject to optical injection. Our analysis …

We propose an electro-optic approach for transparent optical networking, in which frequency
channels are actively transformed into any desired mapping in a wavelength-multiplexed …

Spectral broadening of optical frequency combs with high repetition rate is of significant
interest in optical communications, radio-frequency photonics and spectroscopy. Silicon …

Microwave photonic solutions of frequency measurement have advantages in broad
frequency coverage, but achieving high-resolution measurement remains a challenge …
