Abstract
The present invention relates to a collimator assembly for use in an optical switch. The collimator assembly includes an integrated LED/photodiode plane disposed in a dual microlens array. The integrated LED/photodiode plane results in a relatively simple way to manufacture high port count collimator arrays with integrated monitoring capabilities. The LED/photodiode plane can be readily produced using standard electronics manufacturing technology.
