A Semiconductor Laser For Laser Communications Applications
SPIE Proceedings, 1989A coherent array of 10 amplifiers has been demonstrated using an active integrated optics technology based on AlGaAs laser diode material. These arrays have demonstrated power outputs of 300 mW CW with only 2 mW injected power. The fractional coherence between any two amplifiers in the array is greater than 0.8. These arrays have been used to amplify a

Interplanetary Laser Communications
Optics and Photonics News, 2007Lasers could enable deep-space communication between Earth and planets at the farthest reaches of our solar system. Over the next two decades, optical communications technology is expected to deliver at least an order-of-magnitude higher data rate than conventional radio frequency systems from deep space.

Digital communication with synchronized chaotic lasers
Optics Letters, 1994We propose a scheme for encoding digital data within a spiky chaotic carrier from a loss-modulated solid-state laser. Decoding is performed in real time with a synchronized chaotic laser system.

A communication system is designed to transmit and receive information. The information to be sent is generally superimposed by modulation onto an electromagnetic wave called a carrier. It is then transmitted to a receiver where the information is recovered by demodulation. Various types of communication systems are often designated by the location of

Laser applications to communication
Zeitschrift für angewandte Mathematik und Physik ZAMP, 1965This short review has shown the existence of several serious uncertainties on actual possibilities of long-distance laser communication systems. We must however point out that lasers only appeared a few years ago and that notwithstanding the great effort going on in many laboratories, many aspects of the problems concerning the application of laser to ...
