Ultra-low-loss Ta2O5-core/SiO2-clad planar waveguides on Si substrates
An increasing number of systems and applications depend on photonics for transmission and signal processing. This includes data centers, communications systems, environmental sensing, radar, lidar, and microwave signal generation. Such systems increasingly rely on monolithic integration of traditionally bulk optical components onto the chip scale to significantly reduce power and cost while sim...

متن کاملSidewall gratings in ultra-low-loss Si3N4 planar waveguides.
We demonstrate sidewall gratings in an ultra-low-loss Si3N4 planar waveguide platform. Through proper geometrical design we can achieve coupling constant values between 13 and 310 cm(-1). The TE waveguide propagation loss over the range of 1540 to 1570 nm is below 5.5 dB/m.
متن کاملLow-loss planar optical waveguides in strontium barium niobate crystals formed by ion-beam implantation.
Planar optical waveguides have been formed in strontium barium niobate single crystals by either proton or heliumion implantation. The profiles of the ordinary and the extraordinary refractive indices are deduced from dark-line mode spectroscopy. Optical barriers with depths to Deltan(e) = 2.6% for protons and Deltan(e) = 5.5% for helium are obtained. By proton implantation we find a very low i...
متن کاملLow-loss guided modes in photonic crystal waveguides.
We study disorder-induced propagation losses of guided modes in photonic crystal slabs with line-defects. These losses are treated within a theoretical model of size disorder for the etched holes in the otherwise periodic photonic lattice. Comparisons are provided with state-of-the-art experimental data, both in membrane and Silicon-on-Insulator (SOI) structures, in which propagation losses are...
