Analysis of silicon nitride partial Euler waveguide bends
Florian Vogelbacher, Stefan Nevlacsil, Martin Sagmeister +3
In this work we present a detailed analysis of individual loss mechanisms in silicon nitride partial Euler bends at a wavelength of 850 nm. This structure optimizes the transmissio…
