Abstract
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 signals by use of DPIC.Keywords
