In this work we focus on improving light extraction efficiency of PhC LED. Studied LED structure was based on GaAs/AlGaAs material system. 1D PhC was patterned on the top of the LED structure with 3 different periods (500 nm, 600 nm, 800 nm). Several

We report on a new structure design and optical properties of the coupled edge and horizontal cavity vertical emitting laser (CE-HCSEL) with emission wavelength of ∼1160 nm based on InGaAs/GaAs double quantum well structure in the active layer. The

Periodic arrays of air holes with diameters ranging from about 80 nm up to 400 nm are shown to modify intensity profiles of guided modes in photonic-crystal fibers, suggesting new ways of fiber dispersion engineering and modal birefringence control.

Efficient confinement of laser radiation in the core of a photonic crystal fiber (PCF) enhances the nonlinear processes resulting in supercontinuum generation. The technique of adaptive pulse shaping using an evolutionary algorithm provides a method
