Abstract
Surface acoustic wave (SAW) Bragg-modulators as frequency shifters are attractive for applications in sensors, since they yield high optical and electrical bandwidth. The Bragg-modulator consists of tapered monomode waveguides and the SAW field in between. A Gaussian beam yields a suppression of unwanted frequencies greater than 60 dB below shifted frequency, however, more realistic field distributions yield suppressions of about 20...30 dB.
