The results obtained from luminescence measurements made on one-dimensional optical amplifiers are reviewed. The investigated samples are GaAs/(Ga, Al)As waveguiding structures containing a multiple quantum well structure as active element. The experimenta ...
We present two methods based on the analysis of Fabry-Perot interference for a detailed characterization of a 90degrees corner in a two-dimensional photonic crystal waveguide fabricated in a thin Si membrane. These methods are a means of identifying the cr ...
We present practical and theoretical, stage-by-stage analysis of light propagation around a 90degrees corner in a two-dimensional photonic crystal waveguide. Using a series of different samples we quantify the coupling efficiency between the conventional r ...
A stage-by-stage analysis of light propagation around a 90° corner in a two-dimensional photonic crystal waveguide was discussed. The coupling efficiency between the conventional ridge waveguide and the photonic crystal waveguide was quantified using a ser ...
We present two methods based on the analysis of Fabry-Pérot interference for a detailed characterization of a 90° corner in a two-dimensional photonic crystal waveguide fabricated in a thin Si membrane. These methods are a means of identifying the critical ...
We study the coherent optical response of a very high-finesse microcavity with a single quantum well by means of degenerate subpicosecond pump-probe spectroscopy. The dynamics of the ac Stark effect versus Pump intensity is investigated upon tuning the emp ...
