Abstract
We present an extension to the ray-transfer matrix method, which is often used to characterize optical systems. The main purpose of the extended method is to model micro-optical-bench systems that are usually manufactured using surface micromachining and other microfabrication technologies. Using a homogeneous coordinate system to extend standard ray-transfer matrices allows the matrix notation to account for manufacturing tolerances. As an example of this method's usefulness, we calculate the coupling losses in a surface micromachined fiber-optic switch.
