Abstract- - In this paper, a type of laser which consists of an array of Coupled-Photonic-Crystal-Nanocavities is considered. This laser has a lower threshold power and higher differential quantum efficiency in comparison with a Single-Cavity Photonic Crystal laser. In order to investigate the differential quantum efficiency, first the laser rate equations are calculated. After that, they are evaluated in the steady state. Then, the differential quantum efficiency of Single-Cavity laser is compared with that of Photonic-Crystal laser array.
Keywords: Gain Laser, Differential Quantum Efficiency, Spontaneous Emission-Coupling Factor, Photonic Crystal Laser, Laser Rate Equations
