Y. Awaji et al., Differential-phase-to-intensity conversion based on injection locking of asemiconductor laser, OPTICS LETT, 26(20), 2001, pp. 1538-1540
A novel method of optical phase-shift detection using differential-phase-to
-intensity conversion (DPIC) based on injection locking of a semiconductor
laser is proposed. We predict DPIC numerically and verify it experimentally
. We then demonstrate detection of OC-48 (2.48832-Gbit/s) phase-modulated s
ignals by use of DPIC. (C) 2001 Optical Society of America.
