    Developments in THz Polaritonics: Towards Integrated Nonlinear THz Spectroscopy by Sung, Eric Rueyhao

    Published 2024
    “…A circular stair-step "echelon" mirror is used to shape the pump pulse into a conical tilted pulse front composed of a series of concentric rings of pump light. When the pump rings are imaged onto a thin LT waveguide, coherent superposition of the focusing THz fields excited individually by each pump ring results in a dramatically enhanced THz field at the focus. …”
