Orientation 1 = light proagating along x-axis
Orientation 2 = light propagating along y-axis
Orientation 3 = light propagating along z axis

RHL = right handed circularly polarised light
LHL = left handed circularly polarised light

Monitors:
Freq. and power domain monitor in x = 0 plane; y = 0 plne and z = 0 plane
