InAs基中红外带间级联激光器中的自加热效应
The effects of self-heating on mid-infrared interband cascade lasers grown on InAs substrates
摘要
Abstract
In this paper,InAs-based type-Ⅱ interband cascade lasers operating at the mid-infrared range were fabricated and characterized.The maximum operating temperatures under pulsed and continuous wave (CW) operating mode are determined to be 275 K and 226 K,respectively.The threshold current density is around 17 A/cm2 at 80K with an emission wavelength of approximate 3.8 μm.We analyzed the self-heating effects under CW mode and further simulated the temperature contour by the finite element method.The results indicate that the self-heating effect is a critical factor that limits the operating temperature under CW mode for our devices.Further optimization of the heat dissipation performance would be an effective way to raise the operating temperature of these devices.关键词
