Abstract :
Demonstrates an integrated bulk-wave acousto-optic tunable filter (1.0 nm FWHM) in a multiwavelength crosstalk measurement experiment. With 16 channels present, individual channel crosstalk was lower than -15 dB for both single-wavelength and dual-wavelength filtering. The RF drive power for 70% efficiency was 180 mW/wavelength.
