“…As the best nonlinear medium for supercontinuum generation (SCG), PCFs have a wide range of applications in science and technology, including the fields of optical communication, ________ telecommunication, spectroscopy, medical, security, petrochemical industries biomedical sensing, and more [2,3]. During the past several decades, many attempts to improve the dispersion and nonlinear properties of silica-PCF include altering the cladding shape [5,6], modifying the structural parameters [7,8], or using highly nonlinear fluids to fill their hollow cores [5][6][7]. Even so, the SCG spectrum expansion based on these PCFs is still limited, making it difficult for application areas in the infrared range.…”
