摘要：
Two types of double-stage, acousto-optical wavelength filters have been fabricated in X-cut, Y-propagating LiNbO3 by an integration of TE- and TM-pass polarisers and acousto-optical mode convertors in a doubly confined acoustical/optical singlemode waveguide. Filter characteristics with narrow bandwidth (< 2 nm), a tuning range of approximately 60 nm around lambda = 1.55-mu-m and strongly reduced residual sidelobes have been obtained.
