Title: System and method for efficient coupling between optical elements

Abstract: A system and method for efficient coupling between optical elements comprises a memory containing an alignment module configured to align a light beam with an optical element to maximize coupling efficiency, and a processor coupled to the memory to control the alignment module. A position sensitive device indirectly senses a position of the light beam on the optical element and sends the position to the processor. The alignment module directly measures coupling efficiency where the light beam contacts the optical element. The alignment module identifies a direction of increasing coupling efficiency and aligns the light beam with the optical element along that direction until maximum coupling efficiency is achieved.
