Abstract : A wavelength selective demultiplexer tuner having an optically transmissive body for receiving an input signal containing a plurality of different wavelengths and transmitting the signal therethrough. An electro-optic block of material is secured to the body of the tuner and a reflective grating or mirror is secured to the electrooptic block of material for redirecting through the body the input signal as a plurality of signals, each containing a different one of the wavelengths. By appropriately varying a voltage placed across the electro-optic block of material, the index of refraction of the block of material changes thereby altering the optical paths followed by the plurality of signals redirected through the body. In this manner, each of the signals containing a different one of the wavelengths can be selectively output from the body at different times and at the same, single location. (Author).
