Abstract :
Optical homodyne receivers are very suitable for free-space laser communications, owing to their high sensitivity and frequency selectivity. Phase synchronization by maximizing baseband signal power is less complex than previously proposed strategies, while still offering the key advantages of a 180 degrees hybrid AC-coupled front-end
