Use of photonic crystal cavities for temporal differentiation of optical signals
We show that general-form optical cavities are able to perform the temporal differentiation of optical signals. Analytical relationships to account for the scattering losses for such a cavity's characteristics are deduced on the basis of temporal coupled-mode theory. A compact nanocavity-aided...

Zusammenfassung: | We show that general-form optical cavities are able to perform the temporal differentiation of optical signals. Analytical relationships to account for the scattering losses for such a cavity's characteristics are deduced on the basis of temporal coupled-mode theory. A compact nanocavity-aided differentiator based on a ridge photonic crystal waveguide is designed. |
