| 摘要 |
The present invention relates to a multi-optical coupler and, more specifically, to a multi-optical coupler to output a wide wavelength light by combining lights having different wavelengths and to increase optical power by combining lights having the same wavelength or different wavelengths. To achieve this, the multi-optical coupler comprises: a plurality of input optical waveguides; and a single output optical waveguide which has an input terminal joined to the output terminal of the input optical waveguides and is outputted by joining the lights of the input optical waveguides. |
