Abstract
An integrated device includes a micro-lens and an opto-electronic device can be formed on a single substrate. The opto-electronic device may be one or more photodetectors and the micro-lens may be shaped to allow partial absorption of light incident to the micro-lens by the photodetectors. The integrated device is capable of simultaneously performing position detection, signal monitoring, and focusing/collimation.
