Abstract
A reflection grating with a binary surface profile is presented that h as high diffraction efficiency. The measured intensity for the +1st di ffracted order was 77%. The binary grating is composed of a minilattic e with feature sizes comparable with the wavelength of the incident li ght. The overall structure is designed in such a way that it imitates a conventional blazed grating. The grating also has interesting polari zation properties. The main part of the TE-polarized light is diffract ed into the lst diffracted order, and most of the TM-polarized light r emains in the 0th diffracted order. The measurements of the grating ar e compared with rigorous diffraction theory and found to be in reasona ble agreement.
