ABSTRACT:
A method is disclosed in this invention for designing an optical polarization analyzer for measuring a state of polarization (SOP) of an optical signal transmitted over a particular range of wavelengths. The method includes a step of selecting a corner cube having a specific input medium refraction index and comprising four triangular surfaces and attaching four optical detectors on each of the four surfaces for sequentially absorbing and then reflecting an incident light from one detector to a next detector wherein said incident light is within the particular range of wavelengths. The method further includes a step of selecting a coating to coat over each of the detectors disposed on each of the four surfaces by selecting a coating material and designing an accurately controlled thickness of each of the coatings for controlling a absorption/reflectance ratio for each of the detectors whereby an optimal sensitivity of photopolarimeter is achieved.
