ABSTRACT
A novel, highly accurate, all electronic technique for phase locking arrays of optical fibers is demonstrated. We report the first demonstration of the only electronic phase locking technique that doesn't require a reference beam. The measured phase error is lambda/20. Excellent phase locking has been demonstrated for fiber amplifier arrays.
