A novel means of computing bend loss in rectangular waveguides
A new numerical method based on effective-index method with built-in perturbation correction (EIMPC) is proposed to compute bend loss in integrated optical rectangular waveguides. Applying this method
relationship between bend loss in curved rectangular waveguides and its parameters (height
width and curvature radius) is analyzed. Numerical results of EIMPC are compared with that of mode theory
they agree well with each other. And some results and difference are also discussed.
