Abstract

Apparatus for generating of a comb having a large number optical teeth and comprises an optical loop (3) including an optical amplifier (5) a frequency shifter (4) and an optical filter (6). A signal from a laser (9) is partially coupled into the loop by a coupler (7) such that a part of it is output at output port (10). The signal in the loop (the feedback signal) is amplified by the amplifier (5) and frequency shifted by the frequency shifter (4) and is then partially coupled out of the loop by coupler (7). The part coupled out of the loop (the output signal) exits via output port (10). This process is repeated to produce the desired number of output signals exiting via output port (10). The signal from the laser (9) may be continuous or pulsed.
