Dielectric optical waveguides constitute the main building blocks of photonic integrated circuits (PICs). Channels with high refractive index contrast can provide very compact PIC components whereas structures with lower index exhibit less propagatio

Here, we demonstrate a new type of 3-dB coupler that has an ultra-broadband operational range starting from 1300 nm to 1600 nm with low fabrication sensitivity. Overall device size is 800 micron including in/out S-bend waveguides. The coupler is an a

A novel method for increasing the extinction ratio of plasmonic waveguide polarizer has been investigated in this work. Aluminum was coated in a 20 microns multi-strips pattern on the top of a SU-8 waveguide to excite the surface plasmons. Simulation
