Abstract

The on-chip scale devices are an appealing technology for diverse application, such as all-optical signal processing, frequency metrology, spectroscopy and sensing as the advantages of low cost, compact size and reduced power consumption. By capitalizing the strong optical nonlinearity and reasonable dispersion control of the Ge₂₈Sb₁₂Se₆₀ chalcogenide waveguides, we demonstrate the process of the supercontinuum spectrum generation on the chip and obtain the mutual verification results with the numerical simulation, revealing insights into the soliton dynamics and providing critical device design guidelines. A home-built, palm-sized femtosecond laser centering at 1560nm wavelength was used as the pumping source. Therefore, our work can provide a reference template for future waveguide design and research, such as on-chip Raman soliton source and on-chip optical frequency comb.
