Title: Innovations of Gargi Sharma in Terahertz Radiation Characterization
Introduction
Gargi Sharma is a prominent inventor based in Brampton, Canada. She has made significant contributions to the field of terahertz radiation characterization, holding 2 patents that showcase her innovative methods and systems.
Latest Patents
Her latest patents include a "Method and apparatus for characterization of terahertz radiation." This invention describes a method for characterizing terahertz radiation using spectral domain interferometry. The process involves overlapping a pump beam and a terahertz beam in a detecting crystal, obtaining two probe pulses by propagating the probe beam into a polarization maintaining single-mode optical fiber after the detecting crystal, and measuring a change in the optical path difference between the two probe pulses. The system comprises a detection crystal where a terahertz pulse and a probe beam overlap, a polarization-maintaining optical fiber that propagates the probe beam after the detection crystal and outputs two probe pulses, and a spectrometer where the two probe pulses interfere.
Another notable patent is the "Spectral-domain interferometric method and system for characterizing terahertz radiation." This invention is based on spectral domain interferometry for detecting intense THz electric fields. It allows the use of thick crystals for spectroscopic purposes, enabling long temporal scans for increased spectral resolutions and overcoming the limitations of over-rotation for currently available high power THz sources. Using this method and system, the phase difference of approximately 8898π can be measured, which is 18000 times higher than the phase difference measured by electro-optic sampling (π/2).
