EMISSION OF SINGLE MOLECULES IN SELF ORGANIZED INP GAINP QUANTUM DOTS

Generation of single frequency radiation from a semiconductor laser based on a special laser module (amplifying laser module) is presented. The multi-mode emission with the spectral bandwidth of 100A0 is converted to single mode one with a narrow bandwidth of 2A0 in the presence of external optical[r]

The linear configuration single-mode Distributed Bragg Reflection (DBR) Erbium doped Fiber laser has been tested. The cavity length of the laser utilizing intracore Bragg reflectors, no longer than one centimetre and the grating bandwidth is below ∼ 0.2 nm. The 1.55-µm emission wavelength of the las[r]

The infinite system of differential equations for the nonequilibrium Green functions of electrons in a single-level quantum dot connected with two conducting leads is truncated by applying the mean-field approximation to the mean values of the products of four operators. As the result the system of[r]

We present a rate equation approach (REA) based on the propagation equations in single-mode Erbium-Doped Fiber Amplifiers (EDFAs). Special attention is paid to the gain and the amplified spontaneous emission (ASE) noise as functions of position including the effects of some main parameters such as p[r]

We study the electron spin dynamics in 2D - quantum dots due to the hyperfine interaction with surrounding nuclear spins. The study shows that electron spin dynamics depends strongly on the initial state and polarization of the nuclear spin system. Obtained results has shown that electron spin dynam[r]

The optical resonance of a three-level system of the strongly correlated electrons in the twolevel semiconductor quantum dot interacting with the linearly polarized monochromatic electromagnetic radiation is studied.

Antigen-processing machinery molecules play crucial roles in infectious diseases and cancers. Studies have shown that polymorphisms in endoplasmic reticulum aminopeptidase (ERAP) genes can influence the enzymatic activity of ERAP proteins and are associated with the risk of diseases.

The present study was aimed at assessing the socio-economic impact of organized retail farmers. A sample size of 100 retail farmers and 100 non-retail farmers was selected. A binary logit model was used to analyze the impact of organized retail marketing. The results revealed that in comparison to n[r]
