260 GHz laser-driven semiconductor switches with performance rate up to nanosecond

Long-Pulsed Modulation Regimes of Subterahertz Nanosecond Waveguide Switches

“…Intrinsic properties of Gallium Arsenide crystal help to achieve nanosecond level of switching performance with green driving laser emission [3]. The resonant waveguide cavity construction ensures low phase distortion to the packets' at the output [4]. The output phases are linked to each other once the input microwave signal is coherent, e.g.…”

“…The output phases are linked to each other once the input microwave signal is coherent, e.g. a gyrotron in a phase stabilization regime [4,5]. The prospective application of the switches is the new generation of DNP-NMR (Dynamic Nuclear Polarization -Nuclear Magnetic Resonance) spectroscopy featuring low power on probing objects and expanded resolution.…”

260 GHz CW gyrotron heating substitution with second-long laser pulses in waveguide semiconductor switches

“…The main advantage of the switches is low distortion to the phases of the packets' high frequency fillings at the output [4]. The phases are linked to each other since the microwave input emission is coherent, e.g.…”
