An optical frequency converter using reciprocating modulation includes a device that, taking n as a predetermined integer of 1 or more, modulates light of a predetermined frequency to produce an nth order sideband group thereof, a device that modulates the nth order sideband group to produce an (n+1)th order sideband group, and a device that selects a specific sideband from a plurality of sideband groups. <IMAGE> |
