Slow-light birefringence and polarization interferometry.
By performing two-beam coupling experiments in a liquid-crystal light valve, we report a large slow-light birefringence (SLB) phenomenon, with orthogonal polarization states traveling at very different group velocities. We show that SLB can be exploited for realizing a common-path polarization interferometer able to detect phase variations with enhanced sensitivity.
