An optical encryption technique based on polarization property of light is proposed. Many techniques using polarization
beam splitters to encrypt the signal have been proposed earlier. They are based on splitting and interference of two light
signals, namely message and noise. Only by placing suitable mirrors and a second beam splitter in a suitable position,
the two signals are reconstructed at the output. In this paper we report the fiber optic version of a polarization based
encryption technique that also has the potential to double the data carrying capacity of the fiber. Using polarization
dependent couplers in the fiber optic cables, we are able to achieve encryption of the light signal. Theoretical analysis
and simulated results are also presented.
