Dynamics and Stability of Long-Wavelength Quantum-Well Lasers with Phase-Conjugate Feedback

摘要

Investigation and modeling of dynamics and stability of long-wavelength quantum-well lasers with carrier transport effects subject to a phase-conjugate mirror has been developed. Unremovable in quantum-well lasers carrier transport affects significantly both cw and dynamic laser performance. Laser stability, phase locking, and dynamics have been studied by the analysis of the laser rate equations describing optical field and carrier transport including carrier diffusion is separate confinement heterostructures, carrier capture and escape in quantum wells. It has been shown, that in long-wavelength quantum-well lasers carrier transport narrows drastically the laser-stability region in ≈1.5 to ≈2.5 times and increases the unstable-output oscillation frequency in ≈2 to ≈3 times.
