A novel lightwave‐driven detector that combines photomultiplier tube (PMT) technology with
structured metasurfaces is presented to enable efficient detection of long‐wavelength …

Using a nonlinear optical mixing known as a frequency up-conversion process, we
demonstrate an optical cross-correlation technique for the detection and characterization of …

In this article, we analyzed the influence of modulation frequency and duty cycle on the
responsivity of Golay cell in terahertz (THz) measurement by establishing an energy transfer …

The method for achieving non-collinear phase matching in stimulated polariton scattering
(SPS) using cross-pumping is proposed. Under sub-nanosecond pulse laser pumping …

In this paper we report a compact and robust regenerative amplifier developed as the pump
laser for a high repetition rate terahertz parametric amplifier. With properly chosen pump …
