Abstract:
An optical transmitting/receiving module, comprising:a substrate having a flat surface, in which a linear V-groove and a groove are formed in such a manner that both said V-groove and said groove are facing said flat surface, said groove crossing obliquely said V-groove at an end of said V-groove, an optical fiber core being received in said V-groove in such a manner that an end of said optical fiber core is positioned at one end of said V-groove at which said groove crosses, said groove having a side surface which is not perpendicular to optical axis of said optical fiber core; a wavelength selective filter or a half-mirror received in said groove; a light emitting element arranged on said flat surface of said substrate at a position corresponding to an extension of said optical fiber core in transmitting direction of said wavelength selective filter or said half-mirror such that a light is transmitted from said light emitting element to said wavelength selective filter or said half-mirror without propagating through a waveguide; and a light receiving element arranged on said flat surface of said substrate in reflecting direction of said wavelength selective filter or said half-mirror such that a light is transmitted from said wavelength selective filter or said half-mirror to said light emitting element without propagating through a waveguide.
