A controllable nanosize combiner in T-shaped metal-insulator-metal waveguides

[摘要] References(13)We numerically analyzed the performance of a T-shaped combiner with metal-insulator-metal plasmonic waveguides. We showed that an extremely low combining loss can be realized over a wide infrared wavelength region. Moreover, the combining efficiency can be controlled between 0 and 1 by changing the phase difference between two input light sources, and it appears to be insensitive toward unequal powers of input light sources. Finally, we proposed a novel, optical 90° hybrid coupler with a modified T-shaped structure.
