Advanced arrayed waveguide gratings: models, design strategies and experimental demonstration

Gargallo Jaquotot, Bernardo Andrés (Universitat Politècnica de València, 2016-11-28)

[EN] The present PhD thesis deals on the model, design and experimental demonstration of Arrayed Waveguide Grating (AWG) with advanced features. Firstly, building upon existing AWG formulations, design equations are provided, ...
Nonlinear focusing of ultrasonic waves by an axisymmetric diffraction grating embedded in water

Jimenez, Noe; Romero García, Vicente; Picó Vila, Rubén; García-Raffi, L. M.; Staliünas, Kestutis (American Institute of Physics (AIP), 2015-11-16)

We report the nonlinear focusing of ultrasonic waves by an axisymmetric diffraction grating immersed in water. In the linear regime, the system presents high focal gain (32 dB), with a narrow beam-width and intense side ...
Periodic time-domain modulation for the electrically tunable control of optical pulse train envelope and repetition rate multiplication

Tainta, Santiago; Erro Betran, Mª Jose; Amaya Ocampo, Waldimar Alexander; Garde. María José; Sales Maicas, Salvador; Muriel Fernandez, Miguel Angel (Institute of Electrical and Electronics Engineers (IEEE), 2012-01)

An electrically tunable system for the control of optical pulse sequences is proposed and demonstrated. It is based on the use of an electrooptic modulator for periodic phase modulation followed by a dispersive device to ...
Reflective arrayed waveguide gratings based on Sagnac loop reflectors with custom spectral response

Gargallo Jaquotot, Bernardo Andrés; Muñoz Muñoz, Pascual; Baños López, Rocío; Giesecke, Anna Lena; Bolten, Jens; Wahlbrink, Thorsten; Kleinjans, Herbert (Optical Society of America: Open Access Journals, 2014-06-16)

In this paper, a model for the analysis and design of a reflective Arrayed Waveguide Grating is presented. The device consists of one half of a regular AWG where each arm waveguide in the array is terminated with a phase ...
Undergraduate experiment with fractal diffraction gratings

Monsoriu Serra, Juan Antonio; Furlan, Walter D.; Pons, Amparo; Giménez Valentín, Marcos Herminio (European Physical Society, 2011-03-11)

We present a simple diffraction experiment with fractal gratings based on the triadic Cantor set. Diffraction by fractals is proposed as a motivating strategy for students of optics in the potential applications of optical ...
