Abstract

A study of acousto-optic deflection addressing switch of 1 X N is reported in this paper. The switch device that we have developed consists of a pair of optical waveguide geoidesic lenses, a titled chirped electrode transducer and a Ti:LiNbO₃ waveguide on a piece of LiNbO₃ substrate in order to achieve the optical deflection addressing function. A single mode fiber and an array of single mode fiber (N) are coupled with the two endfaces of device respectively. The device is a multiplex channel switch. The device working wavelength is 1.55 micrometer. The waveguide geodesic lenses are designed by an optimum analytical method. The non- spherical concave lenses spherical aberrationless in the apertures of beam. That is fabricated in single point diamond turning method. The titled chirped electrode transducer bandwide was designed 200 MHZ. The experiment at 0.633 micrometer He-Ne light source show that the results coincide with the theoretical design. The insertion losses of the device is 8 dB about and the channel's crosstalk is better than -20 dB. Switch has a broad range of applications. Currently, the most promising applications are in the fields of lightwave communications and optical signal processing.
