Angular dependence of the emission intensity can be successfully controlled by using back‐cavity effect in a multi‐cathode structure. It is useful for this technique to optimize optical properties, without sacrificing electrical properties. In addition, surface plasmon loss in the cathode is significantly suppressed as a result of optical coupling between waveguide mode and long‐range surface plasmon mode. Approximately 60% of optical power can be utilized as external mode.
