Abstract

Embodiments herein include an optical system, an optical component, and an associated method of passive alignment in which complementary magnetic patterns are used to provide passive alignment between optical elements. The magnetic coupling between the magnetic patterns operates to align optical elements in at least two dimensions. The magnetic coupling provides a temporary holding force on the optical elements until the optical elements are secured using epoxy or other adhesive.
