    We demonstrate an extremely nonlinear all-dielectric metasurface that employs intersubband polaritons to achieve a second-harmonic conversion coefficient of 3 mW/W2, and second-harmonic power conversion efficiency of 0.045% at a modest pump intensity of 6.7 kW/cm2.

    We report terahertz quantum cascade laser sources based on intra-cavity difference-frequency generation processed into double-metal waveguides with surface-grating outcouplers. Over 112 μW of peak power output is produced at room temperature at 1.9 THz.

    Abstract

    Reported is the measurement of infrared absorption spectra of 4‐nitrothiophenol and hydroxyl‐terminated hexa(ethylene glycol) molecules at apices of functionalized atomic force microscope (AFM) probes using resonantly enhanced infrared photoexpansion nanospectroscopy, also known as resonantly enhanced AFM‐IR technique. The experiment demonstrates the applicability of the AFM‐IR technique to perform spectroscopy of only a few tens of molecules on AFM tip apices and demonstrates the potential of the AFM‐IR technique to perform vibrational spectroscopic studies of chemical reactions and molecular conformational changes on the apices of functionalized AFM tips.
