Journal ArticleDOI
Nanoimprinted passive optical devices
J. Seekamp,S. Zankovych,A H Helfer,P Maury,C. M. Sotomayor Torres,G. Böttger,C. Liguda,Manfred Eich,B Heidari,Lars Montelius,Jouni Ahopelto +10 more
TL;DR: In this paper, the feasibility and process parameters of nano-print lithography to fabricate low refractive index passive optical devices are reported, and the expected Bragg peak is observed in transmission and atomic force microscopy images have shown a good pattern transfer.
Journal ArticleDOI
Three dimensional photonic crystals in the visible regime
TL;DR: In this article, the authors show how to use col- loidal crystals as templates for photonic crystals and how to monitor the changes of their optical properties due course of the modification.
Journal ArticleDOI
Erasing diffraction orders: Opal versus Langmuir-Blodgett colloidal crystals
Sergei G. Romanov,Maria Bardosova,D. E. Whitehead,Ian M. Povey,Martyn E. Pemble,C. M. Sotomayor Torres +5 more
TL;DR: In this article, the optical transmission of photonic crystals self-assembled from colloidal nanospheres in opals and assembled from two-dimensional colloidal crystals in a periodic stack by the Langmuir-Blodgett technique has been compared.
Journal ArticleDOI
Size dependence of the thermal broadening of the exciton linewidth in GaAs/Ga0.7Al0.3As single quantum wells
H. Qiang,Fred H. Pollak,C. M. Sotomayor Torres,W. E. Leitch,A. H. Kean,Michael A. Stroscio,Gerald J. Iafrate,Ki Wook Kim +7 more
TL;DR: In this article, the temperature dependence of the linewidth of the fundamental absorption edge in bulk GaAs and four GaAs/Ga0.7Al 0.3As single quantum wells of different well width using photoreflectance was studied.
Journal ArticleDOI
A self-stabilized coherent phonon source driven by optical forces.
Daniel Navarro-Urrios,Nestor E. Capuj,Jordi Gomis-Bresco,Francesc Alzina,Alessandro Pitanti,Amadeu Griol,Alejandro Martínez,C. M. Sotomayor Torres +7 more
TL;DR: A novel injection scheme that allows for “phonon lasing” in a one-dimensional opto-mechanical photonic crystal, in a sideband unresolved regime and with cooperativity values as low as 10−2 is reported.
