N2 - Quantum cascade lasers (QCLs) are the light source of choice for many mid-infrared (mid-IR) applications. An active region (AR) of a typical InGaAs/AlInAs mid-IR QCL consist of 30-40 stages. The operating voltage of such devices is typically 8-12 V, which prohibits the use of standard laser diode drivers, typically limited to 5 V output. Additionally, high number of quantum cascade stages N P result in trapping of ohmic heat in the thermally poorly conducting ternary AR layers. As a result, mid-IR QCLs typically require advanced thermal management such as buried heterostructure (BH) processing to operate continuous-wave (CW) at room temperature (RT).
