    • A polarization switching apparatus (20) has a first birefringent polarizer (22a) formed as a composite prism and disposed to direct incident light of a first polarization along a first optical path and light of a second polarization along a second optical path, wherein the second optical path is oblique to the first optical path. A beam redirector (28) is disposed to redirect the first optical path from the first birefringent polarizer toward an input face of a second birefringent polarizer (22b); wherein the second birefringent polarizer is also formed as a composite prism and is disposed to combine incident light of the first and second polarizations onto a common output path. A shutter apparatus (46) is actuable to selectively block light of the first polarization or light of the second polarization from the input face of the second birefringent polarizer.
    • 偏振切换装置具有形成为复合棱镜的第一双折射偏振器,并且设置成沿着第一光路引导第一偏振的入射光和沿着第二光路的第二偏振光,其中第二光路相对于 第一光路。 光束重定向器设置成将第一光路从第一双折射偏光镜朝向第二双折射偏振器的输入面重定向; 其中所述第二双折射偏振器还形成为复合棱镜,并且设置成将所述第一和第二偏振的入射光组合到公共输出路径上。 快门装置可致动以从第二双折射偏振器的输入面选择性地阻挡第一偏振光或第二偏振光。

    • Optical connectors for connecting optical fiber to a light source are disclosed. In one embodiment, an optical connector includes a housing with a first end having an open aperture and a second end having a blind aperture. A chamber is disposed in the housing such that the optical axis of the housing passes through the chamber. The chamber includes a first material. A light collecting region formed from a second material is disposed in the housing between the second end of the housing and the chamber. A blind aperture is positioned in the light collecting region such that a termination of the blind aperture is spaced apart from the chamber by at least a portion of the second material. A refracting surface is disposed in the housing between the open aperture and the light collecting region such that the optical axis of the housing passes through the refracting surface.
    • 公开了用于将光纤连接到光源的光学连接器。 在一个实施例中,光学连接器包括具有开口的第一端和具有盲孔的第二端的壳体。 腔室设置在壳体中,使得壳体的光轴穿过腔室。 该室包括第一材料。 由第二材料形成的聚光区域设置在壳体的壳体的第二端和腔室之间。 盲孔位于光收集区域中,使得盲孔的终端与第二材料的至少一部分与腔隔开。 折射表面设置在开口孔和集光区域之间的壳体中,使得壳体的光轴穿过折射表面。
