Latest Patents
One of his latest patents is focused on packaging for high power pump laser modules. This invention utilizes locally heated low temperature solder glass to permanently fix an optical fiber with sub-micron precision to a glass ceramic submount inside a high power pump laser module. The process involves manipulating the fiber into a predetermined alignment while the solder glass is still molten, allowing for adjustments to compensate for thermally related dimensional changes as the solder glass cools. This method has proven to provide reliable and efficient coupling of optical fibers to high power pump lasers within very tight tolerances. Another significant patent is the low loss wavelength selective optical switch. This fast-acting switch is designed for optical fiber communication systems and incorporates a small diameter waist region with a precisely tuned Bragg grating. By shifting the waist, the periodicity of the grating is varied, allowing the selected wavelength to pass through with virtually no loss. This technology offers distinct advantages for wavelength division multiplexed systems.
