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 ...
