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 ...

Applications of Two-Dimensional Photonic Crystals to Semiconductor Optoelectronic Devices
After a brief review of the role of optics in semiconductor optoelectronic devices, we show which kinds of two-dimensional photonic crystal might find their way to the applications, taking into account feasibi...

Photoconductivity of Diamond-Like Carbon
We have studied the photoconductivity in pure tetrahedral amorphous carbon (ta-C) and hydrogenated tetrahedral amorphous carbon (ta-C:H). Good photoconductive properties are demonstrated for ta-C:H, showing th...
