Optical frequency combs (OFCs) are a unique kind of light source, which are represented as
a series of equally spaced coherent spectral lines in the frequency domain. OFCs can …

Optical frequency division based on bulk or fiber optics provides unprecedented spectral
purity for microwave oscillators. To extend the applications of this approach, the challenges …

Mode-locked lasers (MLLs) generate ultrashort pulses with peak powers substantially
exceeding their average powers. However, integrated MLLs that drive ultrafast …

Optical isolators are indispensable components of almost any optical system and are used
to protect a laser from unwanted reflections for phase-stable coherent operation. The …
