Abstract: A diode-laser-based active transducer integrated on a heat-assisted magnetic recording head includes a diode laser structure, as a laser source, and a waveguide-transducer integrated with the laser structure as an intracavity element. Being a part of the laser cavity, the waveguide-transducer very efficiently delivers and couples the high-intensity intracavity laser light to a plasmonic antenna/transducer that concentrates the delivered near-field light to an optical spot of subwavelength nano-size volume to locally heat the surface of the magnetic recording medium.

Abstract: A new monolithic Atomic Force Microscopy (AFM) active optical probe monolithically integrates a base of the probe, a cantilever, a semiconductor laser source, an AFM tip, and a photodetector into a robust, easy-to-use single semiconductor chip to enable AFM measurements, optical imaging, and optical spectroscopy at the nanoscale.

Abstract: A new resonant-cavity-enhanced Atomic Force Microscopy (AFM) active optical probe integrates a semiconductor laser source and an aperture AFM/near-field scanning optical microscopy (NSOM) probe in either external-resonant-cavity or internal-resonant-cavity configuration to enable both conventional AFM measurements and optical imaging and spectroscopy at the nanoscale.
