摘要
An optical tunable filter that includes an tunable acousto-opto deflector (AOD) for deflecting a broad band beam to an expander for projecting the broad band beam to a set of grating for generated a tuned output beam corresponding to a deflection from the AOD and a wavelength resolution of the set of gratings. The AOD further includes an RF driver for tuning the AOD with an RF driving signal. The AOD further comprises a directional tuning acousto-optic crystal. The optical beam expander further includes a first and a second beam expanding prisms that composed of a material suitable for a dense wavelength division multiplexing (DWDM) application over a wavelength range covering S, C and L bands.
