Design for Y-branch waveguides with wide angle and low loss |
|
|
Abstract: |
A novel method to design Y-branch waveguides is proposed by using total internal reflection, and the optical properties are
analyzed. The simulated results show that the optical loss values of two Y-branch waveguides with the branching angles of
12° and 30° are only 0.310 dB and 0.645 dB, respectively. Compared with conventional Y-branch waveguides, the optical performance
of the proposed ones is well improved, which has many advantages such as wide angle, low loss, simple structure and easy for
fabrication. |
