Bifurcations and interacting modes in coupled lasers: A strong-coupling theory
Wieczorek, Sebastian; Chow, Weng W.
The synchronization between two coupled lasers was analyzed using a strong-coupling theory. The influences of pump, carrier decay rate, polarization decay rate and coupling mirror losses on synchronization between lasers were investigated using bifurcation analysis, supported by insight provided by analytical solutions. It was found that population pulsation is an essential mode competition mechanism responsible for bistability in the synchronized solutions. The mechanism leading to laser synchronization changes from strong composite-cavity mode competition in class-A regime to frequency locking of composite-cavity modes in class-B regime was discovered.
