High-speed switching of far-infrared radiation by photoionization in a semiconductor.

چکیده
An investigation of subnanosecond switching of 119-microm radiation achieved by irradiating high-resistivity silicon wafers with 1.7-ns, 337-nm pulses from a nitrogen laser is presented. The experimental results are compared with a one-dimensional numerical multilayer model, which accounts for the generation, recombination, and diffusion of the free carriers and the resulting change of the far-infrared optical properties of the Si wafer.

Chapter 3 . High - Frequency ( > 100 GHz ) and High - Speed ( < 10 ps ) Devices
The millimeter-wave and THz frequency (f > 100 GHz) range remains one of the most underdeveloped frequency ranges, even though there are a great number of potential applications in remote sensing, spectroscopy, plasma diagnostics, and communications. This is because the millimeter wave and far-infrared frequency range falls between two other frequency ranges, the microwave frequency range and t...

متن کاملSimulation and Experimental Verification of Closed Loop Operation of Buck / Boost DC-DC Converter with Soft Switching
A major problem in an isolated DC/DC converters operating at high switching frequencies is the attendant switching losses in the semiconductor devices. This can be reduced by introducing either zero-voltage switching (ZVS) or zero-current switching (ZCS) of the semiconductor switches. This paper deals with the simulation, design, fabrication and experimental evaluation of a novel soft-switching...
