- Abstract
Integrated photonics have been growing at an exponential rate. The related technologies are advancing with numerous research works on integrated devices offering Complementary Metal–Oxide–Semiconductor (CMOS) compatibility. Various compact waveguides are also exploited for different applications. In this paper, we report an unconventional 5 mm long air-clad SiN suspended core channel waveguide that is CMOS compatible. The hollowed-out Silica (SiO2) rectangular substrate serves as the lower cladding for the Silicon Nitride slab on which the rectangular core is suspended. The envisioned waveguide is engineered to be numerically pumped at 1.55 μm wavelength with a pulse that is 20 kW in power and 50 fs in duration. The generated Supercontinuum spanning from 0.8 to 6 μm has a great potential in bio-medical and imaging applications.
