Wideband E00-E10 Silicon Mode Converter Based on 180 nm CMOS Technology

Mode division multiplexing (MDM) is a promising technology for the capacity enlargement of optical transmission network. As key element in MDM system, mode converter plays an important role signal processing. In this work, wideband E00-E10 silicon constructed by Y-branch and cascaded multimode interference coupler demonstrated. The theoretical crosstalk less than –29.2 dB within wavelength range from 1540 nm to 1600 nm. By 180 standard CMOS fabrication, tested conversion efficiency 91.5% −10.3 can be obtained at 1575.9 3 bandwidth over 60 proposed applicable multiplexing.
