Title: Implementation of pulse position modulated blue-green laser communication system
Abstract: Blue-green laser communication has many advantages over traditional VLF radio communication especially to a submerged subject. An experimental blue-green laser communication system employing optical pulse position modulation (PPM) is developed. The principle of PPM modulation method is analyzed, and the corresponding frame format is presented. Then the detailed design of PPM modulator and demodulator are separately described, and the practical implementation of the transmitting and receiving systems are realized. Results show that the whole communication system is compact, efficient, reliable and inexpensive. It has achieved a high-speed rate communication up to 5M bits/s and a reasonably low error rates to 10<sup>-4</sup>. Further research of this PPM modulated system will provide advantageous reference to underwater, space and other optical communication.
