Planar optical waveguide loss

Statistical study of radiation loss from planar optical waveguides: The

This article presents an original method for the theoretical analysis of the intensity radiated by a dielectric waveguide with rough walls. The method is based on Maxwell''s equations under their

Introduction to the Special Issue on Ultralow Loss Planar

An increasing number of applications require lower planar waveguides losses and advances in materials, waveguide design, processing techniques and monolithic and heterogeneous integration.

A theoretical analysis of scattering loss from planar optical

Inaddition, we show that forany waveguide there is a simple upper limit for the scattering loss.

Analysis of guided and leaky modes of planar optical waveguides

We present a numerical approach to compute and characterize both guided and leaky modes in a multilayer planar optical waveguide made of any lossy and dispersive materials.

Numerical analysis of planar optical waveguides using matrix approach

We present here a simple matrix method for obtaining propagation characteristics, including losses for various modes of an arbitrarily graded planar waveguide structure which may have media of complex

Waveguide Loss

To quantitatively describe the optical loss, the exponential attenuation coefficient is generally used. In this case, the intensity (power per unit length) decays along the waveguide.

Design and Analysis of a Low-Loss 1 × 2 POF Splitter Based on

To address the demand for low-cost, low-loss, and environmentally friendly optical power dividers in short-range visible light communication (VLC) systems, a low-loss 1 × 2 Y-branch optical

A theoretical analysis of scattering loss from planar optical waveguides

We derive analytical expressions for the scattering loss in planar optical waveguides whose surface roughness can be described by an exponential or Gaussian autocorrelation function.

Effect of multilayer substrate interference in planar waveguide

Scattering loss due to a nanoscale interface roughness has been an unavoidable effect limiting planar waveguide performance, especially when the evanescent field at the core-cladding interfaces is

Improved method for loss measurements in planar waveguides

In this paper, a method employing an IP and a RP is developed for loss measurement in planar waveguides. It is demonstrated with an Ag/Na ion-exchanged waveguide. The experimental
