Latest Patents

One of Sharma's latest patents focuses on the alignment of optical components. This invention involves the alignment of a near-field transducer (NFT) optical input coupler and a light-emitting device. The process includes providing excitation radiation from an excitation light source through an optical input coupler to the NFT. It also involves filtering output radiation from the NFT using a short wavelength pass optical filter. The optical input coupler is scanned through multiple positions while detecting photoluminescent radiation. A first alignment position between the NFT input coupler and the excitation light source is identified based on the detected radiation. Additionally, a light-emitting device is scanned through multiple positions, and the light output is detected by a detector. A second alignment position between the light-emitting device and the detector is identified, allowing for precise alignment of the light-emitting device with the optical input coupler.

Another significant patent by Sharma pertains to the peg height of near-field transducers. This method characterizes the peg region of a near-field transducer incorporated into a write head of a HAMR magnetic recorder. The method includes providing excitation radiation to one or more near-field transducers, which consist of an enlarged disk region and a peg region. The output radiation from the near-field transducers is filtered, allowing for the detection of photoluminescent radiation emitted in response to the excitation radiation. This innovative approach enables the characterization of the peg region of the near-field transducers.
