We measure the angular dependent response of a Swiss-cross metamaterial that has an effective index of n=-1.9 at normal incidence. It is experimentally shown how the effective properties depend on the incidence angle.
Optical microcavites fabricated by etching whispering gallery mode and photonic crystal structures in a high-index gallium phosphide layer and an underlying single-crystal diamond substrate are studied experimentally and theoretically.
We report on the first Sb-based type-I laser grown on GaAs substrate operating continuous-wave around 2.2 mum at room-temperature. The device was grown using solid-source molecular beam epitaxy and comprised two GaInAsSb quantum-wells embedded in AlGaAsSb barriers. Despite the large lattice-mismatch, a good crystalline quality was obtained, and processed devices operated continuous wave up to 50degC,...
We demonstrate 2 ps temporal resolution of time-to-space mapping using double quasi-velocity-matched electrooptic deflectors operating at 16 GHz repetition frequency. Deflectors were fabricated on a single stoichiometric LiTaO3 substrate with ldquoUrdquo shaped modulation microstrip line.
We describe a method for integrating fiber optics in substrates by femtosecond laser ablation. In a first demonstration, we fabricate an optically integrated microfluidic device that counts cells by small angle light scattering.
Measurements of an electrooptic tunability of a channel array waveguide, fabricated by ion implantations through a comb-like stopping mask, revealed that the implantation through the active volume of the device didn't diminish its electrooptic properties.
Low expansion glass cavities with optically contacted mirrors can exhibit structural distortions at the mirrors which significantly shift the temperature at which dv/dT=0. An analytical analysis that incorporates finite element modeling is given.
