Abstract
An all-fibre frequency shifter operating at 3 MHz is described. The device was based on a SAW structure using interdigital transducers on a PZT4 ceramic substrate. Carrier and sideband suppression were 29 and 35 dB, respectively, with 4.5% of the input optical power shifted for an electrical drive of 2 W.Keywords
