Abstract
We describe efficient beam splitters for the equi-partition of infrared input power using combined reflection and transmission by a strip-coated all-dielectric slab. Because no metal coating is used, high efficiency is achieved. The beam splitters use a fused silica parallel-slab that is strip coated with germanium on the front and back sides. Specific designs for operation at 1.55, 2.02 and 5.0 µm wavelengths are presented.
