Abstract
A polarization beam splitter (PBS) based on cascaded step-size multimode interference (MMI) coupler is demonstrated on silicon on insulator. The total area of MMI sections is smaller than 7×600  μm 2 . This PBS shows 25-nm bandwidth for transverse-electric polarization and 20-nm bandwidth for transverse-magnetic polarization with an extinction ratio more than 20 dB. The length of this PBS is reduced to about one ninth of that of the conventional design in MMI sections.
