Title: Ashish Madhukar Vengsarkar: Innovator in Optical Technologies
Introduction
Ashish Madhukar Vengsarkar, based in Berkeley Heights, NJ, has made significant contributions to the field of optical technologies, evidenced by his impressive portfolio of 31 patents. His innovations primarily focus on enhancing the capabilities of optical communication systems.
Latest Patents
Among his latest inventions is the patent for "Broadband Long-Period Gratings." This innovative design arises from the discovery that long-period gratings can be engineered to have a center wavelength where the slope characteristic changes polarity near a target wavelength. This chirping technique allows for a wider bandwidth, achieving 100 nm compared to conventional chirped gratings that only provide around 20 nm. These advanced gratings are particularly beneficial in optical communication systems for dispersion compensation and aiding spectrally dependent optical amplifiers.
Another notable patent is for a "Method and Apparatus for Monitoring Multi-Wavelength Optical Systems." This invention involves an optical fiber system designed to separate transmitted light's different wavelengths and monitor their respective optical powers. The system includes modifications to in-fiber gratings that couple light between various modes within a wavelength-division-multiplexed (WDM) structure. By adjusting the physical parameters of these gratings, which can involve temperature changes or dimensional alterations, Vengsarkar’s system enhances control over coupling processes in fiber optic systems.
