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...

Reprocessing of thermally oxidized aluminum arsenide (AlAs) in epitaxial multilayers without delamination
Annealing or processing of AlAs that has been subjected to a wet thermal oxidation process can result in severe delamination of material at the oxidation front. This paper reports a procedure for preventing th...

Finite-depth and intrinsic losses in vertically etched two-dimensional photonic crystals
We address the issue of out-of-plane losses in two-dimensional (2D) photonic crystals (PC) etched through a GaAs monomode waveguide clad with standard GaAlAs alloys. We correlate experimental transmission of P...

Transmission properties of two-dimensional photonic crystal channel waveguides
We study the transmission properties of straight channel waveguides designed in a two- dimensional (2D) photonic crystal patterned into an AlGaAs heterostructure. 2D dispersion calculations show the existence ...
