Abstract
© 2018 SPIE. Group-velocity dispersion (GVD) engineering is vital to many nonlinear optical phenomena and has been widely used for nonlinear optics. Aiming at different applications, one need to control and engineer the sign, value, slope of dispersion and the number of zero-dispersion wavelengths (ZDWs). In this work, we demonstrate generation of 5 ZDWs in a new type of bilayer waveguides. Outer layer of this waveguide can be formed by depositing without etching. Material combinations are Ge23Sb7S70 (n≈2.2) and Ge28Sb12Se60 (n≈2.6). In this waveguide, an extremely wideband-low and flat dispersion can be obtained from 2.6 to 15.5 μm (2.6 octaves).
