Abstract

The threshold gain temperature dependence of composite resonator vertical cavity laser (CRVCL), a dual-cavity version of the vertical cavity surface emitting laser (VCSEL) was investigated. The layers of CRVCL was consisted of a substrate, a highly reflective bottom distributive Bragg reflector (DBR), the active region of the bottom cavity, a middle DBR of 85% reflectivity, the active region of the upper cavity, and a atop DBR. When the top cavity had no applied bias, only the short wavelength mode operated, the threshold gain was relatively high, and the device stopped lasing around 55°c. It was observed that by increasing the fixed current, the range of temperatures, over which the long mode lases at threshold, was decreased.
