Phase Noise Reduction of an Optical Frequency Comb Using a Feed-Forward Heterodyne Detection Scheme
IEEE Photonics Journal, 2016 A novel feed-forward phase noise reduction scheme is introduced to reduce the phase noise of an optical frequency comb. The phase noise of a single comb line is measured using a heterodyne technique, and the inverse of this signal is then applied to the ...

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.

Optical Frequency Combs Generated by Acousto-Optic Frequency-Shifting Loops [PDF]
IEEE Photonics Technology Letters, 2019 A recirculating loop that includes an acousto-optic frequency shifter (AOFS) constitutes a versatile procedure to generate an optical frequency comb (OFC) from a continuous wave (cw) laser. This scheme, implementable with conventional fiber equipment, is capable of producing spectra composed of at least hundreds of coherent lines using a single-stage ...
