Tunable Fabry-Perot Fiber Filters
The FFP-TF and FFP-TF2 are versatile tunable filters, consisting of an all-fiber Fabry-Perot super-cavity in a robust, fast tuning Tecordia-qualified package.
Luna Innovations’ patented Fiber Fabry-Perot (FFP) Tunable Filter achieves high finesse and maintains low loss in a rugged package.
The key to the simple and elegant design of the FFP tunable filter is its lensless all-fiber construction. There are no collimating optics or lenses, eliminating the pitfalls of other Fabry-Perot component technologies, including misalignment, environmental sensitivity, and extraneous modes.
The FFP tunable filter follows the Airy function. Engineers can design it into OEM systems knowing that it will provide results very close to the theoretical mathematical model.
The FFP-TF2 design provides improved etalon alignment for stable long-term, high reliability, and Telcordia-qualified performance. Several standard low-cost configurations are readily available for quick delivery. Custom high performance multi-band configurations are also available for specialized applications.
