Patent ID: 6869479

Claim:
A method of laser-assisted fabrication of microstructured optoelectronic and photonic components using deposition of inorganic or organic target materials, such as Cr 2 O 3 , TiO 2 , Al 2 O 3 , MnO 2 , Fe 2 O 3 , diamond, polystyrene, polyamide, polyacetylene, porphyrins, MEH-PPV, forming the microstructure with required refractive index, relief, shape, waveguiding or light focusing properties on the surface of a solid state substrate, including both amorphous and crystalline, semiconductor, dielectric or metal substrates, such as glass, fused silica, silicon, sapphire, GaAs, InP, GaN, CdS, CdSe, ZnSe, comprising the steps of immersing the surface of said substrate into at least one liquid having an appropriate precursor of said target material, irradiating the surface of said solid state substrate with a CW or pulsed laser beam at the wavelength of operation corresponding to the spectral region of absorption either in the solid state substrate or liquid, tightly focused to the microscopic region of material deposition to selectively hear the microscopic region and create a gas bubble in said liquid forming a microscopic clean room for deposition of said target material, continuing the process until said target material forms the microstructure with required relief and shape onto the surface of said solid state substrate, removing surface of said solid state substrate from said liquid, wherein either said solid state substrate material or liquid should remain sufficiently transparent for laser beam at the wavelength of operation allowing irradiation of said surface of solid state substrate, or other means of delivery of the laser beam to said surface of solid state substrate is used.
