Pulse Generation using a Degenerate Band Edge Structure

We propose a pulse generation scheme based on a fourth-order degeneracy in the dispersion relation. We take advantage of the loaded quality factor enhancement and the ultra-sensitivity to external perturbations due to the high order degeneracy in such a structure. The proposed scheme is able to produce a train of nanosecond pulses with several watts of output power. Such a design offers a flexibility that allows to conceive either high output power pulses or high frequency train of pulses.
