Terahertz quantum cascade lasers operating up to 178 K with copper metal-metal waveguides

We report terahertz quantum cascade lasers, with a three-quantum-well active region design and copper metal-metal waveguides, operating up to a record temperature of 178 K. Their performance is compared to devices with gold metal-metal waveguides.
