抄録

We fabrieated and experimentally evaluated 2 × 1 tapered multimode interference (MMI) combiners on silicon-on-insulator (SOI) substrates. The tapered MMI combiner we previously proposed is expected to be free from the reflection problem usually existed in a conventional rectangular MMI coupler, and such a negligible back-reflection property was actually verified. As one of its applications, we implemented a Mach-Zehnder (MZ) modulator using the tapered MMI combiner, which is often equipped with semiconductor optical amplifiers (SOAs) for ultrahigh-speed photonic switching devices and those SOAs are quite sensitive to the back-reflection.
