“…6 (b), respectively. It is noticeable that the switching contrast of the proposed optical switch, S 3 , that is based on Fano resonance effect, is enhanced significantly compared to the result in the previous work in which the optical switch operation is based on nonlinear Kerr effect [18]. Also the switching contrast of proposed structure, S 3 , is greater than the switching contrast in other reports in which the operation of optical switches is based on nonlinear effects [19][20][21].…”

“…A PhC cavity, basically a Bragg grating cavity based on periodic dielectric structures satisfying the Bragg condition [34,35], provides high spatial light confinement in a diffraction-limited cavity. The confined light in the cavity enhances the effective light-matter interaction cross section, making PhC cavities attractive for various applications such as lasing and optical switching [36][37][38].…”

“…Therefore, all-photonic switching can be used as a gist element in constructing onchip all-optical switch networks. Alloptical devices using different optical materials and based on nonlinear optical response have received much attention in recent years [6][7][8][9]. Recently, studies in metal nanocomposite material, all-photonic switching with low pump power have been reported [10].…”

A new all-photonic switching of nonlinear optical materials with very low signal/noise background was presented. Fe and Mg were used to prepare doped and co-doped PbS/PVA freestanding nanocomposite; films were prepared by a simple chemical method with different doping concentrations. The X-ray diffraction patterns, scanning electron microscope images, and optical absorption spectrum of the prepared films were examined. The crystallinity and optical band gap of the prepared co-doped PbS/PVA were found to be affected by Fe and Mg, doping concentrations. The all prepared samples showed a blue shift in the absorption spectra and the optical band gap was increased when the doping concentration is increased. The all-optical switching effect performance of metal doped and (Fe, Mg) co-doped PbS/PVA with various Fe and Mg concentrations were investigated. The results showed that the (Fe, Mg) co-doped PbS/PVA at 1.2%M Fe and 0.8%M Mg doping concentration can demonstrate an active all-photonic switching device and lead to the realization with maximum modulation depth of 86.5% and switching contrast of 8.8 dB at minimum switching time of 47 ms.
