Interferometer and sensor based on bimodal optical waveguides, and detection method

Abstract

[ES] Interferómetro de guías de onda planas (15, 25, 35, 45) que comprende: un sustrato (8, 28, 38, 48); una guía de onda bimodal (10, 20, 20', 30, 40) que a su vez comprende al menos una capa (1, 2, 3) depositada en dicho sustrato (8, 28, 38, 48), dicha guía de onda bimodal (10, 20, 20', 30, 40) está diseñada para soportar un modo transversal de propagación de orden cero y otro de orden primero, dichos modos transversales de propagación poseen diferente dispersión; una placa sensora (21, 31, 41, 51) situada en una zona concreta de la parte superior de dicha guía de onda bimodal (10, 20, 20', 30, 40), dicha placa sensora (21, 31, 41, 51) está diseñada para recibir un estímulo químico, biológico o físico, dicho estímulo es capaz cambiar el índice de refracción efectivo de la guía de onda bimodal (10, 20, 20', 30, 40). La guía de onda bimodal (10, 20, 20', 30, 40) comprende medios (9) diseñados para confinar la luz en dirección lateral, la guía de onda bimodal (10, 20, 20', 30, 40) está, por tanto, diseñada para soportar un modo lateral. Se presentan un chip, sensor y método de detección que comprenden un interferómetro de guías de onda plana.

[EN]: Planar optical waveguide interferometer (15, 25, 35, 45) comprising: a substrate (8, 28, 38, 48); a bimodal waveguide (10, 20, 20', 30, 40) comprising at least one layer (1, 2, 3) deposited on said substrate (8, 28, 38, 48), said bimodal waveguide (10, 20, 20', 30, 40) being designed for supporting a zeroorder and a first-order transverse propagating modes, said transverse propagating modes having different dispersion; a sensor plate (21, 31, 41, 51) located in a selected area of the upper side of said bimodal waveguide (10, 20, 20', 30, 40), said sensor plate (21, 31, 41, 51) being designed for receiving a chemical, biological or physical stimulus, said stimulus being capable of changing the effective refractive index of said bimodal waveguide (10, 20, 20', 30, 40). The bimodal waveguide (10, 20, 20', 30, 40) comprises confining means (9) designed for confining light in lateral direction, the bimodal waveguide (10, 20, 20', 30, 40) being thus designed for supporting one lateral mode. Chip, sensor and sensing method comprising a planar optical waveguide interferometer are provided.
