    Summary

    Terahertz (THz) quantum cascade lasers (QCLs) offer a novel semiconductor platform for two-photon emission. This design enhances light intensity through resonant two-photon processes in THz QCLs.

    Area of Science:

    • Optics and Photonics
    • Semiconductor Physics
    • Quantum Electronics

    Background:

    • Two-photon emission from single electron relaxation has been theoretically proposed but limited by suitable gain media.
    • Terahertz (THz) frequency quantum cascade lasers (QCLs) present a promising semiconductor structure for achieving two-photon emission.

    Purpose of the Study:

    • To propose and design a THz QCL heterostructure capable of resonant two-photon emission.
    • To investigate the dynamics and performance of such a two-photon THz QCL.

    Main Methods:

    • Design of a THz QCL heterostructure for two-photon emission.
    • Development of coupled Maxwell-Bloch equations to model the laser dynamics.
    • Analytical solutions for steady-state light intensity and carrier densities.

    Main Results:

    • The designed THz QCL heterostructure facilitates two resonant photons per electronic relaxation between same-parity states.
    • Simulations predict significantly enhanced light intensity compared to conventional THz QCLs.
    • Increased photon-driven carrier transport rate observed.

    Conclusions:

    • Resonant two-photon emission in THz QCLs is a viable mechanism for enhanced laser performance.
    • The proposed THz QCL design overcomes limitations of previous two-photon laser approaches.
    • This work paves the way for advanced THz light sources with improved intensity.
