Abstract
An optical data transmission apparatus includes a hole-burning effect element for recording data. Upon transmitting input serial data in a multiplex mode along a single optical fiber, the input serial data are stored in the hole-burning effect element having an inhomogeneous broadening on the light absorption spectrum, and then light transmitted through the hole-burning effect element is transmitted over the optical fiber. At the receiver end, the laser light is divided into a plurality of portions having different wavelengths and these portions are made incident upon a light receiving element array. Alternatively, a reading light pulse is made incident upon the element to generate a single light pulse having the spectrum distribution corresponding to the serial data on the frequency domain, and the light pulse is transmitted to the receiver end to duplicate the light absorption spectrum on a receiver end hole-burning effect element which is irradiated by a reading light pulse to generate light pulses corresponding to the duplicated light absorption spectrum, and these light pulses are successively made incident upon a photodetector to reproduce the input serial data.
