Microstructures of composite materials can exhibit properties significantly different from their individual constitution. By utilizing these unique characteristics, we design diffractive optical elements to demonstrate transmission-only polarizers for telecommunications. The transmittance and the extinction ratio of the proposed structure are >95% and >40 dB at 1470-1910 nm wavelengths, respectively. The average reflectance for random polarization is less than 1% at 1350-1580 nm. The methods are applicable to diffractive optics, e.g., in the ultraviolet and visible spectrum.
