KONTRUKSI PT-Symmetry MULTI DIMER PADA DOMAIN TAK HINGGA

Jurnal Lebesgue, 2023
Parity-Time Symmetry, or abbreviated as -Symmetry, can be explained as the propagation of an optical beam in two bound waveguides, where one waveguide experiences strengthening and the other waveguide experiences weakening, with each intensity having the

Slow-light and evanescent modes at interfaces in photonic crystal waveguides: optimal extraction from experimental near-field measurements [PDF]

, 2011
We develop a systematic approach for simultaneous extraction of the dispersion relations and profiles of multiple modes in periodic waveguides though a special global optimization procedure applied to near-field electric field measurements in the ...

Polymeric Optical Waveguide

The Review of Laser Engineering, 1992
PROBLEM TO BE SOLVED: To satisfy the transparency and heat resistance and further to fulfill the workability and optical isotropy which have been incompatible with heat resistance so far by using a specified polyurethane contg. an asymmetric spiro ring as the optical core and/or optical clad. SOLUTION: A polyurethane shown by the formula and contg.

In situ loss measurement of direct UV written waveguides using integrated Bragg gratings

, 2010
The propagation loss of a direct UV-written silica-on-silicon waveguide is measured using an elegant nondestructive method. The technique uses integrated Bragg grating structures, which are observed from opposing launch directions to obtain information ...
