Latest Patents
One of her latest patents is an optical demultiplexor. This device utilizes a single optical interference filter positioned between the input and output ends. The filter is housed within a cavity in a glass block, featuring an upstanding input end and an endwall. The optical filter is designed to selectively allow different wavelengths of light to pass through based on the angle of incidence. The device incorporates multiple reflective surfaces at the input end, which reflect light back to the filter at various predetermined angles. This innovative design enables the separation of up to sixteen channels of light.
Another significant patent is for a narrow band filter and the method of making it. This optical filter consists of first and second graded index (GRIN) lenses arranged in a coaxial relationship. Each lens has ports located at predetermined positions, allowing for tunability of the filter's center wavelength. By adjusting the port locations, the filter can be fine-tuned to a desired wavelength before the positions are fixed, enhancing its manufacturing versatility.
