Abstract

The majority of today's optical communication systems employ non-coherent detection or what is commonly referred to as direct detection. However, recent advances in technology have made the concept of coherent optical detection feasible. A properly designed coherent system can offer a significant improvement in receiver sensitivity. In addition a coherent system based on diode pumped Nd:YAG technology offers the additional advantages of high source power and high reliability. This paper describes the system performance of a coherent Nd:YAG system'in terms of receiver sensitivity and compares that performance to that of a typical direct detection system. A comparison is also made between Nd:YAG and semiconductor laser diodes when used in coherent systems.
