High-Sensitivity Polarization-Independent Biochemical Sensor Based on Silicon-on-Insulator Cross-Slot Waveguide

Slot waveguides reported so far are strongly polarization dependent. The concept of a novel cross-slot waveguide (WG) is presented here, which contains both vertical and horizontal slots and supports the power enhancement in the slot region for both the quasi-TE and quasi-TM polarizations. This WG c...
