Direct laser writing and chemical etching and optical devices

摘要

The present invention relates to optical devices that include a single substrate of an optically transparent material. The single substrate forms at least one collection lens (104a-104f) and a channel (106a-106f) therein, the channel (106a-106f) receives the optical fiber, and the collection lens is An optical fiber inserted therein is configured to align light collected by the optical lenses (104a-104f) into the optical fiber.
