摘要	A microlens structure is mounted directly onto the upper surface of a packaged VCSEL device and positioned to locate microlenses directly over corresponding VCSEL elements. The microlens structure includes a block-like pedestal having a lower surface that faces the upper surface of the VSCEL device. The microlenses are formed in a central region of the lower surface, and several legs (stand-offs) extend from peripheral edges of the lower surface. During assembly, the VCSEL device is positioned under the microlens structure such that each microlens is aligned over its corresponding VCSEL element, and then raised until the legs contact the upper surface of the VCSEL device. The legs serve to self-align the microlenses to the VCSEL device, and are sized to maintain an optimal distance between the microlenses and the VCSEL elements. The pedestal is attached to a carrier plate that is secured to an IC package housing the VCSEL device.
其他摘要	微透镜结构直接安装在封装的VCSEL器件的上表面上，并定位成将微透镜直接定位在相应的VCSEL元件上。微透镜结构包括块状基座，其具有面向VSCEL器件的上表面的下表面。微透镜形成在下表面的中心区域中，并且多个支腿（支座）从下表面的外围边缘延伸。在组装期间，VCSEL器件位于微透镜结构下方，使得每个微透镜在其相应的VCSEL元件上对准，然后升高直到腿接触VCSEL器件的上表面。腿用于使微透镜自对准到VCSEL器件，并且尺寸设计成保持微透镜和VCSEL元件之间的最佳距离。基座连接到承载板，承载板固定到容纳VCSEL装置的IC封装。
主权项	An assembly comprising: a light emitting/detecting integrated circuit (IC) device including a substrate having a planar upper surface, and at least one light emitting/detecting element integrally fabricated on the substrate adjacent to the upper surface; and a microlens structure including a pedestal having a planar lower surface and a plurality of legs extending from the lower surface, and at least one microlens integrally fabricated on the lower surface of the microlens structure; wherein the microlens structure is mounted onto the upper surface of the light emitting/detecting device such that each of the plurality of legs contacts a corresponding region of the upper surface of the substrate, whereby the microlens is maintained at a predetermined distance from the light emitting/detecting element.
