Reducing the polarization dependent coupling coefficient in planar waveguide couplers |
| 摘要 |
A planar light wave circuit may include a directional coupler with two waveguides come close to one another in a so-called gap region. Polarization dependent coupling may be reduced by forming trenches on either side of the gap region to reduce birefringence.
