Operator for Optical Polarization
Hari Prakash, Ravi Shankar Singh · Journal of the Physical Society of Japan · 2000
For monochromatic light propagating along z -direction, we define a polarization operator which is product of inverse annihilation operator for the x -linearly polarized mode and the annihilation operator for the y -linearly polarized mode. This polarization operator is helpful in testing whether light in a given state is perfectly polarized, and in knowing this perfect polarized state.
