摘要： An optical waveguide element having a directional coupler is disclosed. The element includes a first and a second waveguide located adjacent to each other at a predetermined portion for mode coupling, a first dummy waveguide extending from an one end of the second waveguide, a reflector installed on an end surface of the first dummy waveguide, and a second dummy waveguide located adjacent to the first dummy waveguide at a predetermined portion for a mode coupling. The optical signals progressing from the second dummy waveguide to the first dummy waveguide disappear while sequentially passing through the reflector and the second dummy waveguide. In the optical waveguide element, optical signals passing through the first dummy waveguide gradually disappear while passing through the reflector and the second dummy waveguide, thereby improving a bi-directional cross-talk.

摘要： A bidirectional optical triplexer is disclosed, which may be connected to an external optical waveguide and receives first and second optical signals having first and second wavelengths through the external optical waveguide, and transmits a third optical signal having a third wavelength. The triplexer includes a platform having first and second trenches spaced from each other on a first optical path optically connected with the external optical waveguide, a first filter positioned in the first trench for reflecting the first optical signal proceeding through the first optical path to a second optical path, and a second filter positioned in the second trench for reflecting the second optical signal proceeding through the first optical path to a third optical path. The triplexer also includes a first optical receiver for detecting the first optical signal proceeding through the second optical path, a second optical receiver for detecting the second optical signal proceeding through the third optical path, and an optical transmitter for outputting the third optical signal to the first optical path. The first and the second optical receiver may be aligned at a first side of the first and the second trenches and the optical transmitter may be aligned at a second side of the first and the second trenches. The first side is opposite to the second side about the first and second trenches.
