Title
(EN) HIGH INDEX CONTRAST WAVEGUIDE DEVICES AND SYSTEMS
(FR) DISPOSITIFS ET SYSTÈMES DE GUIDE D'ONDE À CONTRASTE D'INDICE ÉLEVÉ
Abstract
(EN)
A high index contrast waveguide device is disclosed and described. In one embodiment the waveguide may include a lithium niobate substrate, a waveguide with a higher refractive index than that of the lithium niobate substrate patterned on a surface thereof, and an electrode electrically coupled to the waveguide. The device may form part of a system for sensing an electric field.
(FR)
L'invention concerne un dispositif de guide d'onde à contraste d'indice élevé. Dans un mode de réalisation, le guide d'onde peut comprendre un substrat en niobate de lithium, un guide d'onde avec un indice de réfraction plus élevé que celui du substrat en niobate de lithium formé sur une surface de celui-ci, et une électrode couplée électriquement au guide d'onde. Le dispositif peut faire partie d'un système de détection d'un champ électrique.
