격자의 구조가 간단하고 격자의 대조비가 낮은 SBC 시스템 구성을 위한 무편광 유전체 다층박막 회절격자를 제작하였다. 제작된 박막의 굴절률과 두께 오차로 인하여, 제작된 회절격자의 회절 효율은 설계보다 낮은 값을 나타내었다. 오차를 발생시킨 원인을 분석하고, 제작된 회절 격자 위에 추가의 코팅을 통하여 회절 효율 보정이 가능함을 시뮬레이션을 통하여 확인하였다. 시뮬레이션 결과를 확인하기 위하여 제작된 회절격자 위에 Ta₂O5 추가층을 제작하고 회절격자를 측정한 결과 회절 효율 보상이 이루어졌으며, 최고 91.7%의 무편광 회절 효율을 얻었다.

We fabricate a polarization-independent dielectric multilayer thin-film diffraction grating for a spectral-beam-combining (SBC) system with a simple grating structure and low aspect ratio. Due to the refractive index and thickness error of the manufactured thin films, the diffraction efficiency of the fabricated diffraction grating was lower than that of the design. The causes of the errors were analyzed, and it was confirmed through simulation that diffraction efficiency could be compensated through an additional coating on the manufactured diffraction grating. As a result of sputtering an additional Ta₂O5 layer on a fabricated diffraction grating, the diffraction efficiency was corrected and a maximum 91.7% of polarization-independent diffraction efficiency was obtained.
