Latest Patents

Pingping Chen holds a patent for an "Integrated narrow bandpass filter array and a method for fabrication thereof." This invention describes a Fabry-Perot type of filter array, where the pass band can be adjusted by varying the thickness of the spacer layer. The integrated filter array consists of a substrate, a lower mirror stack, a spacer array, and an upper mirror stack. The spacer array is formed using a combinatorial deposition technique, allowing for the control of the pass band of each mini-size narrow bandpass filter. This innovation enables the integration of multiple narrow bandpass filters with different pass bands on a single substrate, enhancing fabrication efficiency and product yield compared to conventional methods. The filter array is designed to be compatible with detector arrays and functions effectively across important optical ranges.
