Optical bistability in Ag-Al<inf>2</inf>O<inf>3</inf> one-dimensional photonic crystals

Abstract:

Here, we demonstrate the nonlinear optical responses of Ag-Al2O3 one-dimensional photonic crystals (1D PCs). The linear transmission spectra of the proposed 1D PC show higher transmission at shorter wavelengths and lower transmission at longer wavelengths with "N" pairs of Ag-Al2O3 will support "N - 1" transmission peaks. By using 5 pairs of Ag-Al2O3, the optical bistability behavior of light transmission at low input intensity for the resonant modes is numerically demonstrated. Then, we performed a Z-scan experimental technique to show the enhanced nonlinear optical transmission of Ag-Al2O3 1D PC. These results can pave the way for achieving all-optical control of light for potential applications such as all-optical switching, optical logic, optical computation, etc.
