    摘要： An optical device and method is disclosed for forming the optical device within the wide-bandgap semiconductor substrate. The optical device is formed by directing a thermal energy beam onto a selected portion of the wide-bandgap semiconductor substrate for changing an optical property of the selected portion to form the optical device in the wide-bandgap semiconductor substrate. The thermal energy beam defines the optical and physical properties of the optical device. The optical device may take the form of an electro-optical device with the addition of electrodes located on the wide-bandgap semiconductor substrate in proximity to the optical device for changing the optical property of the optical device upon a change of a voltage applied to the optional electrodes. The invention is also incorporated into a method of using the optical device for remotely sensing temperature, pressure and/or chemical composition.

    摘要： A solid state energy conversion device and method of making is disclosed for converting energy between electromagnetic and electrical energy. The solid state energy conversion device comprises a wide bandgap semiconductor material having a first doped region. A thermal energy beam is directed onto the first doped region of the wide bandgap semiconductor material in the presence of a doping gas for converting a portion of the first doped region into a second doped region in the wide bandgap semiconductor material. A first and a second Ohmic contact are applied to the first and the second doped regions of the wide bandgap semiconductor material. In one embodiment, the solid state energy conversion device operates as a light emitting device to produce electromagnetic radiation upon the application of electrical power to the first and second Ohmic contacts. In another embodiment, the solid state energy conversion device operates as a photovoltaic device to produce electrical power between the first and second Ohmic contacts upon the application of electromagnetic radiation.

    摘要： An apparatus and method is disclosed for increasing the thermal conductivity in a substrate of a non-wide bandgap material comprising the steps of directing a thermal energy beam onto the substrate in the presence of a first doping gas for converting a region of the substrate into a wide bandgap material to enhance the thermal conductivity of the substrate for cooling the non-wide bandgap material. In one example, the invention is incorporated into a carbon rich layer formed within the wide bandgap material. In another example, the invention is incorporated into a carbon rich layer formed within the wide bandgap material having basal planes disposed to extend generally outwardly relative to an external surface of the substrate to enhance the cooling of the substrate.

    摘要： Apparatus, systems, methods and devices of an optical system for producing a laser beam having pitchfork profile. The system includes a laser source providing an input Gaussian beam, refractive optical lenses for converting the input Gaussian beam into a super Gaussian beam. A focusing lens focuses the super Gaussian beam, where by diffraction effect after the focusing lens, the beam profile near a focal spot is a pitchfork shaped beam. In an embodiment, the refractive optical lenses are plano-aspheric lenses. The pitchfork shaped beam is produced by passing the input Gaussian beam through plano-aspheric lenses to produce the super Gaussian output beam, and passing the super Gaussian output beam through a focusing lens to produce the output beam having a pitchfork profile. In an embodiment, the pitchfork shaped beam is applied to laser microvias drilling in electronic packaging to produce residue free holes at reduced production cost with simplified procedures.
