Phys. Rev. A 72, 043818 (2005) [6 pages]Two-field description of chaos synchronization in diode lasers with incoherent optical feedback and injectionReceived 14 July 2005; published 24 October 2005 Synchronized chaotic dynamics are investigated theoretically and experimentally in a system of unidirectionally-coupled semiconductor lasers subject to delayed, polarization-rotated optical feedback and injection. Experimental data in the time and frequency domains demonstrate chaos synchronization with a lag between transmitter and receiver equal to the injection time, also known as driving synchronization. The natural polarization mode of the transmitter is shown to synchronize most efficiently to the orthogonal state of the receiver which is being injected. A full two-polarization model is used for both lasers, and is in good agreement with polarization-resolved experimental measurements. © 2005 The American Physical Society URL:
