Multimode interference based ultra-low loss silicon waveguide crossing

Home    publication    conference    2014    Multimode interference based ultra-low loss silicon waveguide crossing

We design and fabricate waveguide crossing arrays based on optimized multimode interference. Insertion loss of ~0.02dB per crossing and crosstalk <;-40dB at 1550nm operating wavelength and broad transmission spectrum of 90nm are experimentally demonstrated.
