Abstract

Optimal optical parameters of the beam splitter that is used in the division-of-amplitude photopolarimeter are determined. These are (1) 50%–50% split ratio of the all-dielectric beam splitter, (2) differential phase shifts in reflection and transmission Δ r and Δ t that differ by ±π/2, and (3) ellipsometric parameters ( ψ r ,   ψ t ) = ( 27.368 ° ,   62.632 ° ) or (62.632°, 27.368°). It is also shown that for any nonabsorbing beam splitter that splits incident unpolarized light equally, the relationship ψ r + ψ t = π / 2 is always satisfied.
