Development of UV molding Process to Integrate Microlens Array on VCSEL Array for Optical Communication
광통신 용 VCSEL Array상에 Microlens Array를 집적하기 위한 UV성형 공정기술 개발
Abstract
UV molding is a process for integrating micro/nano polymeric optical components on optoelectronic modules. In the present study, a microlens array for vertical cavity surface emitting laser(VCSEL) to fiber coupling was designed, integrated and tested. At the design stage, design variables ware optimized to maximize the coupling efficiency, and tolerance analysis was carried out. At the integration stage, the UV transparent mold was fabricated and the microlens array on VCSEL array was integrated by UV molding process. Finally the coupling efficiency of VCSEL to fiber was measured and analyzed.
