Two-Dimensional Corrugated Waveguides

Yang Zhao and Ivan Avrutsky

One-dimensional corrugated waveguide structures exhibit many interesting optical properties and can be used for optical coupling, optical filtering, as well as in the distributed feedback and distributed Bragg reflector lasers. We have experimentally demonstrated two-dimensional (2D) corrugated waveguides at optical wavelengths by using 2D colloidal crystal.
