Implementation Details
The optical mirror is a reflective mirror, following is a demonstration of the usage of the optical mirror and a comparison of the optical mirror and the termination mirror. Please see the example file Optical_Mirror_Termination_Mirror.icp.

The first figure is a system of a Fabry-Perot resonator, please note that the second optical mirror is flipped to make the cavity symmetrical because there is a phase shift of π from port 2 to port 1. The second figure replaces the second optical mirror with a termination mirror, the two systems give the same results when the reflectivity of the two mirrors are set to be the same.
The following figures are the measurements of the system. The first figure measures the transmission of the systems with a termination mirror, a non-symmetrical optical mirror and a symmetrical mirror, respectively. It clearly indicates the π degree of phase shift from port 2 to port 1. The second figure shows the transmission and reflection of the system, without considering of loss, the transmission and reflection add up to 1.
