Abstract
An optical communication device is provided. One or more pairs of matched diode lasers are located at first and second stations and are connected by a fiberoptic cable. A bit stream is applied to the output beam of the laser or lasers at the first station. The output beam carrying the bit stream passes through the fiberoptic cable to the matched laser or lasers at the second station and combine with the output beam of the receiving laser cavity at the second station to form a combined output beam. The power of the combined output beam is measured and time-dependent changes in the measured output power of the combined output beam is used to read the bit stream. Multiple pairs of matched lasers using different wavelengths may be positioned at the first and second stations. In yet another form of the invention, a frequency injection technique is utilized to modulate the output beam and a deconvolution system is provided to read the bit stream or streams.
