Biased liquid crystal photonic bandgap fiber

We simulate the director structure of all capillaries in a biased photonic crystal fiber infiltrated with liquid crystals. Various mode simulations for different capillaries show the necessity to consider the entire structure. Â© 2008 Optical Society of Am ...

Integration of Site-Controlled Pyramidal Quantum Dots and Photonic Crystal Membrane Cavities

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Kirill Atlasov, Marco Felici, Arun Mohan

Deterministic integration of site-controlled InGaAs/GaAs quantum dots (QDs) with photonic crystal cavities is demonstrated. Fine adjustment of QD position (within similar to 10nm) and emission energy (few meV) allows construction of coupled QD systems. (C) ...

3-D modulable PDMS-based microlens system

Luis Guillermo Villanueva Torrijo, Victor Javier Cadarso Busto

The design, simulation, fabrication and characterization of 3-D modulable micro-optical system based on poly-dimethilsiloxane (PDMS) are presented in this paper. This system consists on two uncoupled PDMS lenses with different diameter (2 and 10 mu m). Und ...

Reversal of the optical force in a plasmonic trap

Olivier Martin, Lina Huang

We study in detail the. optical forces generated by a plasmonic trap on a plasmonic nanoparticle. The permittivity of the trapped particle is tuned using a Drude model. The interplay between the plasmon resonances of the trap and of the particle can produc ...

Micro-optical polarizer with high efficiency

Hans Peter Herzig, Toralf Scharf

Based on liquid crystal polymers (LCP) a compact micro-optical polarizer with high efficiency has been designed and realized. By using cylindrical mierolens arrays made of LCP and index matching layer, a complete separation of both polarization components ...

Polarization Control of Wafer-Fused Long-Wavelength VCSELs using Sub-Wavelength Shallow Gratings

Elyahou Kapon, Benjamin Dwir, Alexandru Mereuta, Vladimir Iakovlev, Andrei Caliman, Kirill Atlasov

Polarization stable, wafer-fused 1310 nm VCSELs employing sub-wavelength shallow gratings on their top DBR and emitting 1.5 mW single mode output power in the 20 degrees C - 75 degrees C temperature range are demonstrated. (C) 2008 Optical Society of Ameri ...

Electro-optic and electro-absorption characterization of InAs quantum dot waveguides

Marco Rossetti

Optical properties of multilayer InAs quantum dot waveguides, grown by molecular beam epitaxy, have been studied under applied electric field. Fabry-Perot measurements at 1515 nm on InAs/GaAs quantum dot structures yield a significantly enhanced linear ele ...

Resonantly Enhanced Near-Field Lithography

Demetri Psaltis

We propose the combination of a planar optical resonator and a solid immersion lens for resonantly enhanced non-contact near-field lithography. Subwavelength small spots can be produced by exciting the Bessel modes of the resonator. (C) 2008 Optical Societ ...

Electric and magnetic resonances in arrays of coupled gold nanoparticle in-tandem pairs

Olivier Martin

We present an experimental and theoretical study on the optical properties of arrays of gold nanoparticle in-tandem pairs (nanosandwiches). The well-ordered Au pairs with diameters down to 35 nm and separation distances down to 10 nm were fabricated using ...

Photonic Crystal Surface Mode Laser

Hatice Altug

We demonstrated lasing from a high quality-factor photonic crystal surface mode, which brings several advantages for easy fabrication and efficient coupling. Temporal measurements indicate nearly ring-down time limited response. (C) 2007 Optical Society of ...
