Ultra Low Loss Planar Waveguides and Their Applications. Ultra-low loss optical planar waveguide technology is a critical research area driven by the need to improve energy effi-ciency and advance
In this work, we demonstrate high extinction (>78 dB) and broadband (1.50-1.62 μm) polarizers fabricated with a low loss planar silica waveguide platform for photonic integration on Si substrates.
Recent advances in opto-electronics and electro-optics have opened the infrared and visible part of the electromagnetic spectrum for communications and general data processing applications. Planar

Based on subwavelength gratings, here, we show that it is possible to create broadband, multimode waveguides with very low propagation losses despite using a strongly absorbing material.
One of the insights of the ATR FTIR investigations presented in section two is that a low SiH4/CH4ratio is preferable, because Si-H bonds absorbing in the optical C band are less pronounced in this case.
Abstract This chapter presents an introduction to the optical waveguides including planar and nonplanar structures. Additionally, an analysis of planner waveguides based on ray-optical approach and
Waveguides are spatially inhomogeneous transparent structures for guiding light, often used for obtaining strong light concentration over substantial distances.
This diffractive waveguide framework was experimentally validated in the terahertz (THz) spectrum using 3D-printed diffractive layers to selectively pass certain spatial modes while rejecting others.
