Maxwell–bloch equations
Web28 aug. 2024 · We present a powerful computational approach to simulate the threshold behavior of photonic-crystal quantum-dot (QD) lasers. Using a finite-difference time-domain (FDTD) technique, Maxwell-Bloch equations representing a system of thousands of statistically independent and randomly positioned two-level emitters are solved numerically. WebIn nonlinear optics, the Maxwell–Bloch equations can be used to describe laser systems. They consist of three first-order equations for the electric field in a single longitudinal cavity mode, which became nonlinear because the system oscillates between at …
