摘要： A unitary multi-optic system has two or more co-molded individual optics molded such that each individual optic is adjacent at least one other individual optic, each individual optic configured to be illuminated with a respective individual radiation source. An optical-blocking barrier is integrally molded with the individual optics and configured to prevent transmission of undesired source emissions between the two or more co-molded individual optics.

摘要： A microlens array may be formed by nanoimprint lithography. Each microlens of the array comprises a plurality of concentric ridges extending from the substrate and separated by concentric grooves. A ratio F of a width of the concentric ridges to a pitch p of the concentric ridges is a function of a radial distance r from a microlens center to the concentric ridges. An effective refractive index n of microlenses depends on a fill ratio of a binary pattern, which depends on the radial distance from the microlens center. A method of manufacturing a microlens array includes forming an imprint resist layer on a substrate, and imprinting the imprint resist layer with a mold having an inversed microlens nanostructure.

摘要： A unitary silicone prescription optic has a molded silicone body comprising: a front surfaceconfigured as a light exit; an integral reflector configured to receive and reflect light from an LED light source; and an integral attachment portion configured to mount the molded silicone body within a housing. The unitary silicone prescription optic has many advantages over conventional optic systems.

摘要： 一种多级复眼透镜的制造方法，先利用光刻方法制备微柱阵列，然后给微柱阵列表面溅射ZnO，利用微喷印机在微柱阵列间隙喷印紫外固化胶，利用液滴滴落次数控制微透镜形貌，得到微透镜阵列；再将六甲基四胺和硝酸锌分别溶于去离子水中，然后将六甲基四胺溶液倒入硝酸锌溶液中得到混合溶液，将微透镜阵列放入混合溶液中，放入水浴锅中水浴；最后取出微透镜阵列用去离子水清洗，烘干得到多级复眼透镜；在减小光信号交联的情况下，可以极大程度提高结构表面疏水性及液滴稳定性；极大提高液滴的稳定性，液滴很难填充到微柱阵列间隙；微透镜间隙的纳米结构可以降低光透性，降低了光信号之间的交联。

摘要： Various embodiments provide a method for fabricating a couplable electro-optical device. In an example embodiment, the method includes fabricating at least one raw electro- optical device on a substrate; applying lens material to a working stamp; aligning the substrate and the working stamp; pressing the substrate onto the lens material until the distance between the substrate and the working stamp is a predetermined distance; and curing the lens material to form an integrated lens secured to the at least one electro-optical device on the substrate. An anti-reflective coating layer may be optionally applied on top of the molded lens. The couplable electro-optical device may be incorporated into a receiver, transmitter, and/or transceiver using passive alignment to align the couplable electro-optical device to an optical fiber.
