Designing and engineering microresonator dispersion are essential for generating
microresonator frequency comb. Microresonator frequency combs (microcombs, Kerr …

In this Letter, we report phase-matched four-wave mixing separated by over one octave in a
dispersion-engineered crystalline microresonator. Experimental and numerical results …

Here, we report χ^(3) χ^(3)-based optical parametric oscillation (OPO) with widely separated
signal–idler frequencies from crystalline aluminum nitride microrings pumped at …

Widely separated optical parametric oscillation (OPO) in an integrated Kerr microresonator
offers a compact, highly coherent, and low‐power laser source, accessing previously …

Optical frequency combs (OFCs) generated in microresonators with whispering gallery
modes are demanded for different applications including telecommunications. Extending …

In this work, we discuss and experimentally investigate the whispering gallery modes
(WGMs) in a 500 μm radius silicon sphere. We begin by reviewing the basics of WGM …

Nonlinear optical effects in integrated microcavities have been studied extensively with the
advantages of strong light-matter interaction, great scalability, and stability due to the small …

Multispectral frequency combs provide new architectures for laser spectroscopy, clockwork,
and high-capacity communications. Frequency microcombs have demonstrated remarkable …

We demonstrate microresonators with sub-wavelength, periodic patterns for high output
power optical-parametric oscillation. Precise control of phase-matching using the …

We show that an evanescent field coupler can break the symmetry of a high quality factor
monolithic ring microcavity, enabling generation of strongly nondegenerate frequency …
