Resumen
An electrically tunable multimode interference (MMI) coupler/splitter
is demonstrated. The device operates by modifying the phase of the
multiple self-images that are formed around the midpoint of the MMI
structure. This provides a simple way to fine-tune the 50:50 output
power split ratio or other arbitrary ratio.
