Abstract

We report on the realization of an diffractive optical isolator for use at 543 nm by the combination of two binary high frequency gratings, corrugated into the surface of a quartz substrate. A single-order grating acts as a polarizing beam splitter with a measured diffraction efficiency of greater 95%. The other grating is a zero-order diffraction with 290 nm period and 1300 nm depth, acting as a quarterwave plate for conical incidence. A good correlation between theoretical and experimental results is demonstrated.
