A one-dimensional optomechanical crystal with a complete phononic band gap

Gomis Bresco, Jordi; Navarro Urríos, Daniel; Oudich, M.; El-Jallal, S.; Griol Barres, Amadeu; Puerto Garcia, Daniel; Chavez, E.; Pennec, Y.; Djafari-Rouhani, B.; Alzina, F.; Martínez Abietar, Alejandro José; Sotomayor Torres, C.M. (Nature Publishing Group, 2014-07)

[EN] Recent years have witnessed the boom of cavity optomechanics, which exploits the confinement and coupling of optical and mechanical waves at the nanoscale. Among their physical implementations, optomechanical (OM) ...
Ad-hoc design of temporally shaped fs laser pulses based on plasma dynamics for deep ablation in fused silica

Hernandez-Rueda, J.; Siegel, J.; Puerto García, Daniel; Galvan-Sosa, M.; Gawelda, W.; Solis, J. (Springer-Verlag, 2013)

[EN] We have analyzed the ablation depth yield of fused silica irradiated with shaped pulse trains with a separation of 500 fs and increasing or decreasing intensity envelopes. This temporal separation value is extracted ...
Correlation of the refractive index change at the surface and inside phosphate glass upon femtosecond laser irradiation

Puerto Garcia, Daniel; Siegel, Jan; Ferrer, Andres; Hernandez-Rueda, Javier; Solis, Javier (Optical Society of America, 2012-10)

[EN] A study of the surface modification induced by single femtosecond laser pulses in phosphate glass has revealed surface swelling at fluences just below the ablation threshold. This behavior is different from that ...
Honeycomb Photonic Crystal Waveguides in a Suspended Silicon Slab

Puerto Garcia, Daniel; Griol Barres, Amadeu; Escalante Fernández, José María; Pennec, Yan; Djafari-Rouhani, Bahram; Beugnot, Jean-Charles; Laude, Vincent; Martínez Abietar, Alejandro José (Institute of Electrical and Electronics Engineers (IEEE), 2012-11-15)

[EN] We report experimental evidence of light guiding at telecommunication wavelengths along line-defect honeycomb-lattice photonic crystal waveguides created in suspended silicon slabs. Numerical results show that the ...
Plasma dynamics and structural modifications induced by femtosecond laser pulses in quartz

Hernandez-Rueda, J.; Puerto García, Daniel; Siegel, J.; Galvan-Sosa, M.; Solis, J. (ELSEVIER SCIENCE BV, 2012-09-15)

[EN] We have investigated plasma formation and relaxation dynamics induced by single femtosecond laser pulses at the surface of crystalline SiO 2 (quartz) along with the corresponding topography modifications. The use of ...
Resolving Light Handedness with an on-Chip Silicon Microdisk

Rodríguez Fortuño, Francisco José; Barber-Sanz, Isaac; Puerto Garcia, Daniel; Griol Barres, Amadeu; Martínez Abietar, Alejandro José (American Chemical Society, 2014-09)

The efficient manipulation of circularly polarized light with the proper handedness is key in many photonic applications. Chiral structures are capable of distinguishing photon handedness, but while photons with the right ...
Sorting linearly polarized photons with a single scatterer

Rodríguez Fortuño, Francisco José; Puerto Garcia, Daniel; Griol Barres, Amadeu; Bellieres, Laurent Christophe; Martí Sendra, Javier; Martínez Abietar, Alejandro José (Optical Society of America, 2014-03-15)

Intuitively, light impinging on a spatially mirror-symmetric object will be scattered equally into mirror-symmetric directions. This intuition can fail at the nanoscale if the polarization of the incoming light is properly ...
Universal method for the synthesis of arbitrary polarization states radiated by a nanoantennas

Rodríguez Fortuño, Francisco José; Puerto Garcia, Daniel; Griol Barres, Amadeu; Bellieres, Laurent Christophe; Martí Sendra, Javier; Martínez Abietar, Alejandro José (Wiley-VCH Verlag, 2014-05)

Optical nanoantennas efficiently convert confined optical energy into free-space radiation. The polarization of the emitted radiation depends mainly on nanoantenna shape, so it becomes extremely difficult to manipulate it ...
