Beamsplitter

beamsplitter
bs

The beamsplitter component represents a thin dielectric surface with associated properties such as reflectivity, tuning, and radius of curvature. It has four optical ports p1, p2, p3, and p4 which decsribe the four beams incident on either side of this surface. p1 and p2 are on side 1 and p3 and p4 are on side 2.

Syntax

bs name R=none T=none L=none phi=0 alpha=0 Rc=inf xbeta=0 ybeta=0

Required

name: Name of newly created beamsplitter.

Optional

R: Reflectivity of the beamsplitter.

T: Transmissivity of the beamsplitter.

L: Loss of the beamsplitter.

phi: Microscopic tuning of the beamsplitter (in degrees).

alpha: Angle of incidence (in degrees)

Rc: Radius of curvature (in metres); defaults to numpy.inf to indicate a planar surface.

xbeta, ybeta: Angle of misalignment in the yaw plane (xbeta) and pitch (ybeta), respectively (in radians); defaults to 0.

Parameters

Listed below are the parameters of the beamsplitter component. Certain parameters can be changed during a simulation and some cannot, which is highlighted in the can change during simulation column. These changeable parameters can be used by actions such as xaxis or change. Those that cannot must be changed before a simulation is run.
