英文摘要	An optical device coupling light between a first light waveguide and either a second light waveguide or a radiation source characterized by the first light waveguide having a core of a predetermined cross-sectional area, a reflective layer or mirror of a high reflectance being disposed on an angle to the axis of the waveguide and occupying only a small portion of the total cross-sectional area of the core so that only a small portion of the light traveling in the core of the first waveguide will be blocked by the presence of the mirror. The second waveguide will have a core diameter substantially smaller than that of the first waveguide and the mirror is mounted in the first core adjacent to the connection with the second core. The radiation source may be either a laser diode, semi-conductor laser or a light emitting diode.
