Bimodal waveguide sensors enabled by subwavelength grating structures

Torrijos-Morán, Luis; García-Rupérez, Jaime; Griol Barres, Amadeu (OSA (Optical Society), 2020-07-16)

[EN] A subwavelength grating sensor based on a bimodal waveguide configuration is presented for continuous in-flow measurements of refractive index variations. An experimental bulk sensitivity of 1350nm/RIU and a limit of ...
Experimental study of subwavelength grating bimodal waveguides as ultrasensitive interferometric sensors

Torrijos-Morán, Luis; Griol Barres, Amadeu; García-Rupérez, Jaime (The Optical Society, 2019-10-01)

[EN] Over the recent years, subwavelength grating (SWG) structures have increasingly attracted attention in the area of evanescent-field photonic sensors. In this Letter, for the first time to the best of our knowledge, ...
Photonic Applications Based on Bimodal Interferometry in Periodic Integrated Waveguides

Torrijos Morán, Luis (Universitat Politècnica de València, 2021-09-02)

[ES] La fotónica de silicio es una tecnología emergente clave en redes de comunicación e interconexiones de centros de datos de nueva generación, entre otros. Su éxito se basa en la utilización de plataformas compatibles ...
Real-time functionalization and biosensing in subwavelength grating bimodal waveguides

Torrijos-Morán, Luis; Martinez-Perez, Paula; García-Rupérez, Jaime (2020-06-24)

[EN] In this paper, we present for the first time experimental results of biosensing processes by using subwavelength grating bimodal waveguides as a refractive index sensors. We demonstrate the detection of 10ppm concentration ...
Slow light bimodal interferometry in one-dimensional photonic crystal waveguides

Torrijos-Morán, Luis; Griol Barres, Amadeu; García-Rupérez, Jaime (Nature Publishing Group, 2021-01-14)

[EN] Strongly influenced by the advances in the semiconductor industry, the miniaturization and integration of optical circuits into smaller devices has stimulated considerable research efforts in recent decades. Among ...
