Latest Patents
One of Hanna's latest patents is a "Multiwavelength light source using an optical parametric oscillator." This invention involves an apparatus designed to generate at least three visible light beams of different output wavelengths for display purposes. It includes a passively mode-locked solid-state thin-disk laser and a device that utilizes an optical parametric oscillator (OPO) to convert the primary light beam into electromagnetic radiation with the desired output wavelengths. The OPO is preferably an optical fiber feedback OPO, which incorporates a nonlinear optical element and a feedback device that recycles a portion of the emitted radiation back to the nonlinear element through an optical fiber.
Another significant patent is the "Optical waveguide and fabrication method." This invention describes an optical waveguide featuring a guiding lamina of optical material that is bonded to a superstructure lamina through direct interfacial bonding. The guiding lamina has modified optical properties that define a light guiding path. A specific example includes a periodically poled LiNbO planar waveguide that is embedded in LiTaO using precision polishing techniques, which is utilized in an optical frequency doubling system.
