Room‐temperature quantum cascade laser packaged module at ∼8 μm designed for high‐frequency response
Abstract A high‐speed, room‐temperature quantum cascade laser packaged module emitting at 8.14 μm is presented. The cavity length of the laser is as small as 0.5 mm, and the threshold current at 298 K is 110 mA. A matching printed circuit board is inserted into the packaged module to reduce the RC c...
