Why is it important?

Introduce a new approach that is using strip waveguides with an adiabatic bend reduces the bending loss and to obtain a specific length suitable for a V-shaped mode converter with a small increment of footprint size in the IOWM. A new shape of 180-deg slot waveguide bends with high power efficiency and low bending loss, which is providing a remarkable enhancement in the performance of integrated optical waveguide modulator for several intgrated photonic circuit applications.
