| 英文摘要 | A TE-TM polarization manipulating (i.e., splitting, combining or filtering) device is constructed from substrate-supported dielectric thin film waveguides. In a 3-port device, two waveguides have cores of different materials and different effective refractive indices. The waveguide cores overlap in a first transition section and one waveguide core has an adiabatic taper; in this section they also separate adiabatically in and are coupled to a second (e.g., output) section where the waveguides are physically separate and optically decoupled. In a 4-port device, two additional waveguides are coupled in a second adiabatic transition section to the first transition section to enable TE or TM modes to be coupled straight through the device from one input port to a directly opposite output port or to be crossed-over from one input port to a diagonally opposite output port. |
