We investigate the effect of fabrication parameters (nonequal surface current densities, impurities inside the structure, etc.) and loss factor on reflectivity and transmittivity measurements from ...

Tunable Fabry-Perot (FP) filters are being increasingly employed in tunable fiber lasers for wavelength selection and tuning. To address single cavity restrictions on transmittivity and achieve ...

Moreover, the spectral data suggested that the transmittivity increases with increasing doping concentration, and optical properties were extremely sensitive to the impurity concentration in the ...

However, the results show that transmittivity increases, indicating that the increase of electromagnetic wave incidence is greater than that of absorption loss, so the total transmittivity increases.

Ulbricht sphere, also known as an integrating sphere, is an optical device used for measuring the reflectivity/transmittivity of optical components and optical flux ...
