Electro-refraction modulation predictions for silicon graphene waveguides in the 1540-1560 nm region

Pérez-López, Daniel; Doménech Gómez, José David; Muñoz Muñoz, Pascual; Capmany Francoy, José (Institute of Electrical and Electronics Engineers (IEEE), 2016-10)

We derive analytical approximations for the variation of the effective indices of the fundamental transverse electric (TE) and transverse magnetic (TM) modes with the chemical potential of graphene in three common types ...
Temperature Sensor Based on Colloidal Quantum Dots PMMA Nanocomposite Waveguides

Bueno Martínez, Antonio; Suárez Álvarez, Isaac; Abargues, Rafael; Sales Maicas, Salvador; J. MARTÍNEZ-PASTOR (Institute of Electrical and Electronics Engineers (IEEE), 2012-10)

In this paper, integrated temperature sensors based on active nanocomposite planar waveguides are presented. The nanocomposites consist of cadmium selenide (CdSe) and cadmium telluride (CdTe) quantum dots (QDs) embedded ...
Transmission and group-delay characterization of coupled resonator optical waveguides apodized through the longitudinal offset technique

Doménech Gómez, José David; Muñoz Muñoz, Pascual; Capmany Francoy, José (Optical Society of America, 2011)

[EN] In this Letter, the amplitude and group delay characteristics of coupled resonator optical waveguides apodized through the longitudinal offset technique are presented. The devices have been fabricated in silicon-on-insulator ...
Transverse Spin and Spin-Orbit Coupling in Silicon Waveguides

Espinosa Soria, Alba; Martínez Abietar, Alejandro José (Institute of Electrical and Electronics Engineers (IEEE), 2016-07-15)

Evanescent and tightly confined propagating waves exhibit a remarkable transverse spin density since the longitudinal component of the electric field is not negligible. In this work, we obtain via numerical simulations the ...
Ultra-compact optical switches using slow light bimodal silicon waveguides

Torrijos-Morán, Luis; Brimont, Antoine Christian Jacques; Griol Barres, Amadeu; Sanchis Kilders, Pablo; García-Rupérez, Jaime (Institute of Electrical and Electronics Engineers, 2021-06-01)

[EN] Switches are essential components in several optical applications, in which reduced footprints are highly desirable for mass production of densely integrated circuits at low cost. However, most conventional solutions ...
