L.; Geuzebroek, Douwe; Geiselmann, Michael; Domínguez, Carlos; Stassen, Andim; Doménech, José David; Zervas, Michael; Leinse, Arne; Roeloffzen, Chris G.H.; Gargallo, Bernardo; Baños, Rocio; Fernández, Juan; Mico-Cabanes, Gloria; Bru-Orgiles, Luis Alberto; Pastor Abellán, Daniel (Institute of Electrical and Electronics Engineers, 2019-09)

[EN] Photonic integration technologies have spread in the past decade by means of foundry models that mirror the electronic-integrated circuit industry developments of the past century. Several monolithic technologies ...
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 ...
Microoptomechanical silicon nitride photonic inclinometer

Fernández Gámez, Arturo (Universitat Politècnica de València, 2022-10-04)

[ES] Siguiendo los pasos de la microelectrónica, la fotónica integrada está empezando a incluir sistemas micro-opto-electro-mecánicos (MOEM) para la creación de dispositivos sintonizables o programables y sensores. La ...
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 ...
