Patent ID: 7345802

Claim:
An optical apparatus comprising: an array of lasers on a semiconductor substrate, each of the lasers in the array of lasers designed to emit light at a wavelength different than other lasers in the array of lasers; a microelectromechanical (MEMS) mirror moveable to receive light generated from any one of the lasers of the array of lasers and to direct the received light from the one of the lasers of the array of lasers towards an output path; an optical fiber configured to receive at least a portion of the light from the one of the lasers of the array of lasers in the output path; a beamsplitter in the output path between the MEMS mirror and the optical fiber, the beamsplitter configured to direct some of the light from the one of the lasers of the array of lasers out of the output path; a position-sensitive detector configured to receive at least some of the light generated from the one of the lasers of the array of lasers directed out of the output path; and a controller configured to receive a signal representative of a position of the light received by the detector and to generate a control signal for use in positioning of the MEMS mirror.
