| 摘要 |
The present invention discloses an optical transmitting/receiving module designed in small size and produced at low cost without the need to use an optical waveguide, which requires complicated process and larger area, and the invention also discloses a method for manufacturing such an optical transmitting/receiving module. According to the present invention, a V-groove running in linear direction and a vertical groove (a groove having vertical side surfaces) crossing obliquely said V-groove at the end of the V-groove, an optical fiber core is arranged to the end of the V-groove, a wavelength selective filter is arranged in the vertical groove, and a light emitting element and a light receiving element are arranged respectively in transmitting direction and reflecting direction of the wavelength selective filter.
