Abstract
A novel Fabry-Perot resonance cavity has been recognized with ruggedized packaging. This cavity is formed by simple planar and concave (or two concave) mirrors—attached at the fiber ends. The concave mirror is precisely aligned to the core of the fiber. The concave lens is fabricated on the end of the fiber by making an indentation of correct geometry and smoothness. The concave mirror has multiple dielectric layers applied on the concave lens to achieve the final, desired optical characteristics. This structure is packaged using novel techniques from which it derives great utility. The resulting packaged assembly is environmentally robust and capable of operating at very high frequencies with low input voltages.
