WebApr 1, 2024 · The radius of the rod corresponding to the effective refractive index of a unit cell is calculated based on Eq. (2). In this calculation, a unit rectangular cell consisting of a silicon rod in the Si 3 N 4 background with a x = 225 nm and a y = 250 nm is used. WebSi3N4 is a dielectric material with a refractive index ~ 2.0 and is transparent in the 400-5000 nm wavelength range. It has a lower thermal coefficient than silicon therefore less prone to thermal fluctuations and owing to lower-index-contrast than silicon, much lower loss can be achieved even at shorter wavelengths.
