Monolithic Self-Fourier Photonic Crystal Laser Array

The proposed project will demonstrate the feasibility of developing a scalable coherent high power laser array using a photonic crystal structure and a monolithic self-Fourier cavity. In the proposed Phase I effort, the optical design of the multicore photonic crystal structure will be analyzed and a monolithic Self-Fourier cavity will be designed. The mode matching properties of a self-Fourier cavity to the photonic crystal structure will be experimentally demonstrated using bulk optics in a scaled experimental demonstration. During the 4-month Option, a monolithic Self-Fourier cavity of the appropriate scale to match the photonic crystal structure will be manufactured and the mode matching capabilities demonstrated. A complete full-scale laser design will be developed for the Phase II project.
