광학 디바이스가 제공된다. 광학 디바이스는, 하나 이상의 미리 결정된 편광 타원 파라미터를 갖는 타원형 편광된 광을 출력하도록 구성되는 제1 광학 요소를 포함한다. 광학 디바이스는 또한, 키랄성을 갖는 복굴절 물질을 포함하며, 제1 광학 요소로부터 타원형 편광된 광을 수광하고, 타원형 편광된 광을 원형 편광된 광으로서 반사시키도록 구성되는 제2 광학 요소를 포함한다. An optical device is provided. The optical device includes a first optical element including an optical waveplate configured to convert an incident light into an elliptically polarized light having one or more predetermined polarization ellipse parameters, and a mirror configured to transmit a first portion of the elliptically polarized light and reflect a second portion of the elliptically polarized light; and a second optical element including a reflective polarizer configured to receive the first portion of the elliptically polarized light from the mirror and reflect the first portion of the elliptically polarized light as a circularly polarized light having a first handedness toward the mirror, wherein the reflective polarizer includes a birefringent material with a chirality.
