| Summary: | 碩士 === 國立臺灣大學 === 應用力學研究所 === 91 === High Efficiency Pixel-defined Color-divider, a novel MEMS optical component, has been presented instead of conventional color-filter. In this research, we have confidently established a complete standard operating procedure for designation, fabrication and proof of innovative optical elements. The research includes two kinds of micro-optical components: square microlens array and blazed grating.
One side of this novel optical component is blazed grating that divides the first order diffractive light into different directions with different wavelength. The other side of component covers with square microlens array that possesses 100% fill factor to enhance the incident light efficiency and defines the pixel position. By means of the color-divided function, optical efficiency of the component is achieved to three times more than the efficiency of conventional color-filter.
Basing on the optical theory, gray-scale lithography, precision electroforming, and optical plastic material molding technique, several kinds of micro optical component could be developed by the novel Optical-MEMS technology. This novel technology also could be applied to many categories such as optical-communication, optical-display, image sensor and optical-inspection, etc. Moreover, the low cost, simple process and mass production would be its advantages to impact the commercial market.
