OPTICAL ELEMENT, DEVICE FOR COATING OPTICAL DEVICE AND METHOD FOR CONNECTING OPTICAL FIBER CONNECTOR TO OPTICAL DEVICE

摘要

PURPOSE: To prevent the leakage of the light passing a waveguide outside by stably connecting an optical fiber connector to an optical device. CONSTITUTION: Not only the problems of connecting fiber pigtails to glass waveguide silicon devices but the purposes of a novel packaging and interconnection technique capable of separating these waveguide devices from the harmful influence of an external environment are achieved by coating these devices with a thin silica cover plate 310 adhered by low-refractive index epoxy. The epoxy acts as a cladding layer 203 extended to optically confine light radiation under the cover plate.
