Group IV photonics hold great potential for nonlinear applications in the near-and mid-
infrared (IR) wavelength ranges, exhibiting strong nonlinearities in bulk materials, high index …

Supercontinuum (SC) has opened up possibilities for numerous applications in optical
communications, signal processing, metrology, and spectroscopy. Supercontinuum …

We propose a silicon strip/slot hybrid waveguide that produces flattened dispersion of 0±16
ps/(nm∙ km), over a 553-nm wavelength range, which is 20 times flatter than previous results …

We propose highly nonlinear slot waveguides with flat and low dispersion over a wide
wavelength range. Si nano-crystal and chalcogenide glass are considered as slot materials …

We propose and analyze a short-length silicon-on-insulator polarization splitter using two
horizontally slotted silicon waveguides. A polarization splitter with a 46.7? μm length and a …

We investigate a silicon nitride (Si 3 N 4) horizontal slot waveguide with silicon dioxide (SiO
2) cladding, which can achieve a flat and low normal dispersion of-15.56 ps/(nm· km) over a …

We investigate the chromatic dispersion properties of silicon channel slot waveguides in a
broad spectral region centered at~ 1.5 μm. The variation of the dispersion profile as a …

In this work, we propose and design a germanium-doped highly dispersive coupled ring-
core fiber (HD-CRF) with two concentric high-index rings for vortex modes. By using a full …

Stretched cavity soliton (SCS) in dispersion-managed nonlinear resonators is numerically
investigated. SCS is found to stretch and compress twice during a round-trip propagation …

The effect of a lower index oxide layer inclusion within a highly doped silica glass slot
waveguide is investigated for optimized supercontinuum generation at telecom …
