Abstract: A system for passive alignment of fibers to an interface of a photonic integrated circuit (PIC) includes an input frame, an actuator, and an output frame. The actuator arranged to apply force along a force axis to the input frame. The output frame including a tip for picking up a plate and transferring the force thereto, the output frame being connected to the input frame such that the output frame may tilt relative to the input frame and the output frame is elastically biased relative to the input frame into a position wherein the tip is aligned on the force axis.
