However, you can only get 15% fiber coupling from a 0.5x0.2 waveguide into a fiber. A common solution is to increase the mode size by tapering down to a narrower waveguide (inverse taper).
The power handling capability of multimode fiber is hundreds times larger than that of single-mode fiber. This property makes multimode fiber very attractive for the applications in the high

Maximum coupling efficiency is achieved for an ideal Gaussian beam (M 2 = 1, no astigmatism) when the convergence of the focused, circular beam equals the effective NAe 2 of the fiber.

When coupling light from one fiber to another, the fraction of light power coupled is called the coupling efficiency. In multimode fibers this can be quite accurately predicted with rather crude methods
In the weak-coupling regime, the fiber length is not much longer than the correlation length. While there may be significant coupling between modes having nearly equal propagation constants, there is

In the strong-coupling regime, the fiber length far exceeds the correlation length, and there is significant coupling between all modes. As a result, the overall GD spread is reduced, and scales with the

A high coupling efficiency is possible if the parameters of the two fibers differ substantially. It is sufficient that the second fiber (receiving the light) has values
