ABSTRACT:
An optical apparatus for generating an optical frequency comb from an optical input signal is realized by transmitting the optical signal through an optical circuit comprising an optical amplifier and a Bragg cell configured in an optical cavity. By aligning the cavity such that the incident light is deflected by the Bragg cell and recirculated therein, on each pass within the cavity the incident light is frequency shifted by a predetermined frequency, producing a comb of optical frequencies, each a time-delayed replica of the incident light. Importantly, the optical amplifier positioned within the cavity substantially compensates for any cavity loss, enhancing the output uniformity of each generated carrier.
