Latest Patents

Among his latest innovations, Mehfuz has developed a patent for a short on wafer laser specifically designed for heat-assisted magnetic recording. This apparatus features a substrate that supports a laser composed of one or more non-self-supporting layers of crystalline material, with a light path length ranging between approximately 40 µm and 350 µm. The technology also incorporates an optical input coupler that channels light from the laser, alongside a waveguide that facilitates the communication of light to a near-field transducer. This transducer then directs energy, stemming from plasmonic excitation, to a recording medium.

In another noteworthy invention, he has patented a laser feedback suppressor for heat-assisted magnetic recording. This recording head integrates a channel waveguide that delivers light to a surface facing the media. The near-field transducer is strategically located at the end of the waveguide to maximize efficiency. The laser's active region features a longitudinal axis aligned with the waveguide's propagation direction, designed with a front facet that minimizes light back reflection.
