ABSTRACT:
A polarization splitter includes first and second glass members, and a polarization splitting layer and an adhesive layer arranged between the first and second glass members, wherein the polarization splitter satisfies α2×E<6000000 and K>0.5, where α is a coefficient of linear expansion of the first and second glass members (10−7/K), E is a Young's modulus of the first and second glass members (108N/mm2), and K is a photoelastic constant of the first and second glass members (nm/mm·mm2/N).
