Suspended Core SiN Channel Waveguide for Broadband Supercontinuum Generation
In this paper, numerical study of supercontinuum (SC) generation of a novel on-chip CMOS compatible 5 mm long air-clad SiN suspended core channel waveguide has been reported. The proposed waveguide is designed to be pumped at 1.55 μm wavelength with a pulse having a 20 kW power and a temporal width of 50 fs. Supercontinuum coverage ranging from 0.8 μm to 6 μm is observed, which can be utilized in various applications such as spectroscopy, optical coherence tomography, and biomedical imaging.
