Ultra Narrow RF-Photonic Tunable Filtering Module

Leveraging Photonwaress industry-leading development and production of fiber optic components and modules, we propose a new class of high-performance RF-Photonic tunable filtering module. The approach is based on recent progress in doped optical fiber, and multiple phase-shifted FBG technologies closely coupled with the fiber index change induced by laser illumination to push the bandwidth, resolution and dynamic range as well as the response time beyond the current state-of-the-art. The novel fiber-optic based RF-Photonics tunable filter system has several advantages over conventional approaches, including ultra-narrow bandwidth with top-flat, high resolution, large tuning range, fast response, and low power consumption. The technical approach will be proven in Phase I through numerical analysis, design, and experiments. The fully functional prototype module will be produced and tested in Phase II for delivery to the Navy.
