In this paper, we present a detailed investigation of three types of tapered distributed feedback (DFB) quantum cascade lasers (QCLs) emitting at $7.2~\mu \text{m}$ . The sampling gratings with different sampling duty cycles were fabricated by hologr

A dual-wavelength quantum cascade laser (QCL) with two shallow-etched distributed Bragg reflectors is designed and fabricated. Based on a heterogeneous active region within a single waveguide, single-mode emission at 7.6μm and 8.2μm was achieved. T

2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz).
As a compact light source with high output power, quantum cascade laser has excellent performance in the range of 1-5THz. By using THz QCL optical comb spectrum in this frequency range, drugs and industrial waste gas can be quickly and effectively de

We report an ultralow power consumption of a quantum cascade laser (QCL) emitting at λ ∼ 4.6 µm operating in continuous-wave mode at room temperature. The ultralow power consumption is achieved by using a high gain active region and shortening th

We demonstrate a quantum cascade laser (QCL) with a chirped sampling grating by altering the sampling duty cycle along the cavity. The chirped sampling grating structure, with an asymmetric coupling coefficient, can be realized by holographic exposur
