A new method of optical memory and reproduction using otical waveguides is presented in this paper. The optical waveguide memory (OWM) is constructed with numerous small portions of index-mismatched material inplayed in a suitable length of optical waveguide channel The Index mismatched portion called "dimple" can be arrayed in accordance with memorable information as bit-memory. The analysis of reflection-mode signal from the dimples is presented using the coupled-mode equation. A method of reproduction of the signal is studied concerning optical heterodyne wave-detection using a frequency-shifted laser diode.
