Optimization of acousto-optic optical frequency combs
Optics Express, 2019 Acousto-optic optical frequency combs can easily produce several hundreds of mutually coherent lines from a single laser, by successive frequency shifts in a loop containing an acousto-optic frequency shifter. They combine many advantages for multi-heterodyne interferometry and dual-comb spectroscopy.

Spectral Peaked Optical Frequency Comb for Highly Sensitive Spectroscopy
Advanced Photonics ResearchOptical frequency combs represent a breakthrough in the field of metrology. Because an optical frequency comb has a large number of comb modes, the optical energy is dispersed over the comb modes, and the optical energy per comb mode is very small.

Microresonator frequency comb optical clock
Optica, 2014 Optical-frequency combs enable measurement precision at the 20th digit, and accuracy entirely commensurate with their reference oscillator. A new direction in experiments is the creation of ultracompact frequency combs by way of nonlinear parametric optics in microresonators.

Advanced Materials, EarlyView.Ceramic‐based V2O5/Fe3O4 hybrid films are shaped into butterfly‐proboscis‐inspired microscroll actuators. Magnetic triggering initiates unrolling, while geometry‐programmed elastic strain energy drives rapid recoil, enabling fast, reversible, durable, and load‐bearing actuation under near‐field magnetic stimulation.
