The optical routing performance is governed by the following key equations:
The bend loss is given by:
$$\alpha_{bend} = \frac{1}{2R} \exp\left(-\frac{2\gamma^3 R}{3\beta^2}\right)$$
Where R is the bend radius, γ is the decay constant, and β is the propagation constant.
The coupling ratio is calculated as:
$$C = \sin^2\left(\frac{\kappa L}{2}\right)$$
Where κ is the coupling coefficient and L is the coupling length.
The insertion loss is given by:
$$IL = -10\log_{10}\left(\frac{P_{out}}{P_{in}}\right)$$
Where Pout and Pin are the output and input powers respectively.
