Design of a high-performance optical tweezer for nanoparticle trap**
Integrated optical nanotweezers offer a novel paradigm for optical trap**, as their ability to confine light at the nanoscale leads to extremely high gradient forces. To date, nanotweezers have been realized...

Investigation of a point-like and plane-wave excitation in 2D photonic bandgap microcavities using Green’s function method
We report on a new model for simulating wave propagation in two-dimensional photonic crystals (PhCs) by means of Green’s functions rearranged to fit on the geometrical and physical properties of the structure ...

Evidence of different β-phases in highly protonated z-cut H:LiNbO3 waveguides by raman scattering
waveguides is demonstrated by the Raman scattering technique. Multimode waveguides have been produced by using pyrophosphoric, benzoic, and diluted benzoic acids as a proton source. The proton-exchanged (PE) ...
