Abstract
A reciprocating optical modulation system includes a device that modulates light of a predetermined frequency by an integer multiple n to produce a group of nth order sidebands thereof; a device that modulates the nth order sidebands to produce (n+1)th order sidebands; and a device that selects at least part of the (n+1)th order sidebands.
Claims24
A reciprocating optical modulation system comprising:
- means 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;
- means that modulates said nth order sideband group to produce an (n+1)th order sideband group;
- and means that selects at least part of said (n+1)th order sideband group.
