Accurate chromatic dispersion characterization of photonic integrated circuits

Mas Gómez, Sara María; Matres Abril, Joaquín; Martí Sendra, Javier; Oton Nieto, Claudio José (Institute of Electrical and Electronics Engineers (IEEE), 2012-06)

An accurate technique to characterize chromatic dispersion and its slope versus wavelength is reported. The method is based on a heterodyne Mach-Zehnder interferometer, which is immune to thermal phase noise by using a ...
Backscattering en microanillos de silicio

Ballesteros García, Guillem (Universitat Politècnica de València, 2013-03-04)

[ES] En este trabajo presentamos un técnica experimental para caracterizar el backscattering en microanillos resonantes de silicio, junto con un modelo analítico capaz de reproducir los resultados experimentales. El modelo ...
Characterizing and modeling backscattering in silicon microring resonators

Ballesteros García, Guillem; Matres Abril, Joaquín; Martí Sendra, Javier; Oton Nieto, Claudio José (Optical Society of America, 2011)

We present an experimental technique to characterize back-scattering in silicon microring resonators, together with a simple analytical model that reproduces the experimental results. The model can extract all the key ...
High efficiency amplified spontaneous emission from a fluorescent anticancer drug-dye complex

Lahoz, Fernando; Oton Nieto, Claudio José; López, David; Marrero-Alonso, Jorge; Boto, Alicia; Diaz González, Mario (Elsevier, 2013-05)

[EN] External amplified spontaneous emission (ASE) efficiency around 30% is reported for an optically active molecule, which at the same time shows antitumor activity. The complex is formed by the covalent binding of an ...
High nonlinear figure-of-merit amorphous silicon waveguides

Matres Abril, Joaquín; Ballesteros García, Guillem; Gautier, Pauline; Fedeli, J.M.; Martí Sendra, Javier; Oton Nieto, Claudio José (Optical Society of America: Open Access Journals, 2013-02-25)

The nonlinear response of amorphous silicon waveguides is reported and compared to silicon-on-insulator (SOI) samples. The real part of the nonlinear coefficient gamma is measured by four-wave-mixing and the imaginary part ...
Linear and nonlinear optical properties of carbon nanotube-coated single-mode optical fiber gratings

Villanueva Ibáñez, Guillermo Eduardo; Jakubinek, M.B.; Simard, B.; Oton Nieto, Claudio José; Matres Abril, Joaquín; Shao, L.Y.; Pérez Millán, Pedro; Albert, J. (Optical Society of America, 2011)

[EN] Single-wall carbon nanotube deposition on the cladding of optical fibers has been carried out to fabricate an all-fiber nonlinear device. Two different nanotube deposition techniques were studied. The first consisted ...
Low TPA and free-carrier effects in silicon nanocrystal-based horizontal slot waveguides

Matres Abril, Joaquín; Lacava, C.; Ballesteros García, Guillem; Minzioni, P.; Cristiani, I.; Fedeli, J. M.; Martí Sendra, Javier; Oton Nieto, Claudio José (Optical Society of America, 2012)

We present the characterization of the ultrafast nonlinear dynamics of a CMOS-compatible horizontal-slot waveguide with silicon nanocrystals. Results are compared to strip silicon waveguides, and modeled with nonlinear ...
Optical phase characterization of photonic integrated devices

Matres Abril, Joaquín; Ballesteros García, Guillem; Mas Gómez, Sara María; Brimont, Antoine Christian Jacques; Sanchis Kilders, Pablo; Martí Sendra, Javier; Oton Nieto, Claudio José (Institute of Electrical and Electronics Engineers (IEEE), 2014-07)

We propose a relatively simple experimental setup, capable of accurately characterizing the optical phase response of an integrated photonic circuit. The setup is based on a phase-noise reduction scheme using an external ...
Procesado todo-óptico en circuitos fotónicos sobre silicio

Matres Abril, Joaquín (Universitat Politècnica de València, 2013-07-08)

[ES] Los cicuitos todo-ópticos pretenden emplear los efectos no lineales presentes en el silicio para desarrollar conmutadores ópticos o puertas lógicas fotónicas ultra-compactas. Estos circuitos al integrarse sobre chips ...
