Description
Brimrose’s Fiber-coupled, Acousto-Optic Frequency Shifters are used to shift the frequency of various optical signals. Due to a Doppler Shift, the frequency of the diffracted first order optical beam in the AO modulator or AO frequency shifter is shifted in frequency (wavelength) by the acoustic carrier frequency (wavelength).
