ABSTRACT:
A guided-wave acoustooptic spectrum analyzer comprises a planar optical waveguide layer with electrodes of a transducer thereon. The electrodes are positioned at the center of a light path under which light is propagated. The light is deflected in response to frequencies of electric signals applied to the electrodes. With the invention, the detectable minimum pulses width of a pulse signal is reduced as compared with the prior art, while the frequency resolution therein is maintained at the same level.
