Dual-Drive Directional Couplers for Programmable Integrated Photonics

Pérez-López, Daniel; Gutierrez Campo, Ana Maria; Sánchez-Gomáriz, Erica; Dasmahapatra, Prometheus; Capmany Francoy, José (IEEE, 2019-07-10)

[EN] We propose and experimentally demonstrate the use of directional couplers with an independent phase actuator on each waveguide. We show the configurations that allow the setting of the splitting ratio and the phase ...
High-efficiency grating coupler for an ultralow-loss Si3N4-based platform

Chmielak, B.; Suckow, S.; Parra Gómez, Jorge; Duarte, V. C.; Mengual Chulia, Teresa; Piqueras Ruipérez, Miguel Ángel; Giesecke, A. L.; Lemme, M. C.; Sanchis Kilders, Pablo (The Optical Society, 2022-05-15)

[EN] Integrated silicon nitride waveguides of 100¿nm height can achieve ultralow propagation losses below 0.1¿dB/cm at the 1550¿nm wavelength band but lack the scattering strength to form efficient grating couplers. An ...
Low-loss inverted taper edge coupler in silicon nitride

Fernández-Vicente, Juan; Baños Lopez, Rocio; Doménech Gómez, José David; Domínguez-Horna, Carlos; Muñoz Muñoz, P. (Institution of Electrical Engineers, 2019-04)

[EN] An inverted lateral taper with one vertical discrete step was designed for a medium confinement silicon nitride waveguide platform in the C-band, as a chip edge coupler, with a predicted insertion loss of 0.58¿dB. The ...
Optical fiber-to-chip assembly process for ultra-low loss photonic devices based on silicon nitride for space applications

Brimont, Antoine Christian Jacques; Zurita Herranz, David; Duarte, V. C.; Mengual, T.; Chmielak, B.; Suckow, S.; Giesecke, A.; PIQUERAS RUIPÉREZ, MIGUEL ÁNGEL; Sanchis Kilders, Pablo (2020-06-24)

[EN] In this work, we demonstrate an efficient fiber array-to-chip assembly process with a high number of input/output ports. The proposed approach is based on using a pre-alignment coupling structure to separately align the ...
Optical Frequency Domain Interferometry for the Characterization and Development of Complex and Tunable Photonic Integrated Circuits

Bru Orgiles, Luis Alberto (Universitat Politècnica de València, 2022-03-28)

[ES] Esta tesis aborda la caracterización de circuitos fotónicos integrados (PIC) usando interferometría óptica en el domino de las frecuencias (OFDI). OFDI tiene una implementación razonablemente simple e interroga al ...
Optimización de biosensores nanofotónicos basados en resonadores de anillo en guías de nitruro de silicio para aplicaciones lab-on-chip

Castelló Pedrero, Lucía (Universitat Politècnica de València, 2021-07-26)

[ES] Actualmente, el Instituto Universitario de Tecnología Nanofotónica (NTC) y la spin-off Lumensia Sensors participan en el proyecto europeo SaPher, donde se pretende desarrollar y comercializar una plataforma de sensado ...
Reconfigurable Reflective Arrayed Waveguide Grating on Silicon Nitride

Fernández Vicente, Juan (Universitat Politècnica de València, 2021-04-29)

[ES] La presente tesis se ha centrado en el modelado, diseño y demonstración experimental por primera vez del dispositivo Reconfigurable Reflective Arrayed Waveguide Grating (R-RAWG). Para la consecución de este dispositivo ...
Reconfigurable reflective arrayed waveguide grating using optimization algorithms

Fernández, Juan; Felip, Joan; Gargallo, Bernardo; Doménech, José David; Pastor Abellán, Daniel; Domínguez-Horna, Carlos; Muñoz Muñoz, Pascual (The Optical Society, 2020-10-12)

[EN] In this paper we report the experimental realization of a reconfigurable reflective arrayed waveguide grating on silicon nitride technology, using optimization algorithms borrowed from machine learning applications. ...
