Relationship between the optical gap and the optical-absorption tail breadth in amorphous GaAs
(American Institute of Physics (AIP), 2004-12-15)
We study the relationship between the optical gap and the optical-absorption tail breadth for the case of amorphous gallium arsenide (a-GaAs). In particular, we analyze the optical-absorption spectra corresponding to some ...

Upconversion of infrared-to-visible light in Pr3+-Yb3+ codoped fluoroindate glass
(1998-08-01)
Bright fluorescence in the visible range has been observed in Pr3+-Yb3+ doped fluoroindate glass under infrared diode laser irradiation. The mechanism which contributes for the upconversion emission is identified and the ...

Antimony glasses with large nonlinear refractive indices, small two-photon absorption coefficients and ultrafast response at telecom wavelengths
(2007-12-01)
Nonlinear (NL) optical properties of antimony oxide based glasses (AG) were characterized for excitation wavelengths from 800 to 1600 m. The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, β, ...

Excited State Absorption of Doped and Undoped Polyanyline
(TAYLOR & FRANCIS LTD, 2010)
Polyaniline is a conducting polymer with appealing electrical and optical properties, arising from the -conjugation along the polymer backbone. The understanding of its excited state absorption is of prime importance for ...
Study of the pump absorption efficiency in D-shaped double clad optical fiber
(Optica Applicata Volume 42, Issue 3, 2012, Pages 587-596, 2012)
In this paper, we evaluate numerically the pump absorption efficiency in a D-shaped fiber. The study is carried out through the ray tracing method in three dimensions. The simulation results show that D-shaped fiber has ...
