Abstract

The transmission through a symmetric 1x1 multi-mode interference (MMI) waveguide can be substantially suppressed by introducing a small asymmetry in the core refractive index. This can be achieved by applying a voltage in reversed bias to half of the waveguide in the lateral direction, so as to involve the anti-symmetric lateral mode, which in the unbiased situation would not participate. Typical plots will be shown for the calculated transmission as a function of the refractive index change.
