Multimode interference based ultra-low loss silicon waveguide crossing
We design and fabricate waveguide crossing arrays based on optimized multimode
interference. Insertion loss of~ 0.02 dB per crossing and crosstalk<;-40dB at 1550nm …

Ultra-low loss and compact coplanar waveguide crossing
A Hosseini, Y Zhang, RT Chen - Optical Interconnects XIV, 2014 - spiedigitallibrary.org
We investigate the loss mechanism in 3-moded multimode-interference couplers that are the
building blocks of a compact and low-loss waveguide crossing structure. Broadband silicon …

Subwavelength metastructures for dispersion engineering in planar waveguide devices
High contrast structures with a sub-wavelength pitch, small enough to suppress diffraction,
exhibit extraordinary optical properties: depending on the design they may behave as …
