OPTICAL COMPONENT FOR SINGLE FIBER BI-DIRECTIONAL TRANSMITTING/RECEIVING MODULE AND SINGLE FIBER BI-DIRECTIONAL TRANSMITTING/RECEIVING MODULE

摘要

PROBLEM TO BE SOLVED: To provide a single fiber bi-directional transmitting/receiving module which has a high degree of freedom in both of transmission and reception and has high optical coupling efficiency.;SOLUTION: In the single fiber bi-directional transmitting/receiving module, a flat surface of a semi-spherical lens 10 and a longitudinal side surface of a rectangular prism are stuck together, a filter is disposed on the stuck surface, an optical signal of prescribed wavelength band made incident from the hemispherical surface of the hemispherical lens is reflected on the filter and is emitted from the hemispherical surface and an optical signal of another wavelength band made incident from the hemispherical surface is transmitted by the filter and is emitted from one surface of the side of the width side of the rectangular prism. The single fiber bi-directional transmitting/receiving module comprises an optical component, an optical fiber, a light emitting element and a light receiving element. Therein, the optical fiber, the light emitting element and the light receiving element are arranged around the optical component for single fiber bi-directional transmitting/receiving module such that respective optical axes intersect the filter at approximately 45° for the filter.;COPYRIGHT: (C)2006,JPO&NCIPI
