Simulation setup. The file waveguide_coupler.lms has two Silicon on Insulator (SOI) waveguides that are 500nm wide and 200nm thick. The space between the waveguides is 50nm. There are two mesh override regions used: 1.One region covers both guides and extends about 100nm outside them, that reduces the size of
The light launched through the prism propagates in the waveguide by total internal reflection, the evanescent field excites the fluorescent samples in the microchannels, and the output is collected through the microlenses. After fabricating and assembling the fluidic substrate and the cover plate, the assembled waveguides
Abstract: A theoretical investigation of evanescent coupling between an optical fiber and a slab waveguide with an asymmetric geometry is presented. The characteristics of right propagation and coupling are obtained through numerical calculations based on simplified coupled-mode and compound-mode equations and
At optical frequencies, evanescent wave coupling in waveguides is an important concept underlying key wire waveguides, evanescent coupling in an array of PPWGs has not previously been considered. Metal PPWGs are ideal THz .. This section covers general set up of a. RF model and uses the computational model
coupled waveguides. Unlike in previous work, we show that the sign of the force can be changed from attractive to repulsive at fixed frequency simply by tuning the relative phase of the system's inputs. Already, research has shown that evanescent fields can be used to trap (8), manipulate. (9), and propel (10) nanoparticles.
Evanescent field coupling is proposed as a practical way of coupling the output of a thin?film laser to an optical waveguide. Relevant parameters are estimated for the case of a GaAlAs LOC laser coupled to a guide. REFERENCES. 1. H. Kogelnik and C. V. Shank, Appl. Phys. Lett. 18, 152 (1971). Google ScholarScitation
20 May 2015 Abstract. A guided-mode (GM) sensor with a dielectric waveguide grating formed on a thin reflective film using Kretschmann configuration is proposed. Numerical results based on a finite-element method approach indicate a significant resolution improvement due to the excitation of a GM supported by the
6 Feb 2008 The sample is stationary while a goniometer scans the angle of the light source where coupling into the waveguide occurs. . The evanescent field, typically extending 30-100 nm into the cover layer, is sensitive to two types of ambient changes: either, a liquid/gaseous sample is covering the sensing region
