摘要：
We present an ultra-broadband two-mode de/multiplexer based on a multimode interference coupler with sub-wavelength grating waveguides, a symmetric Y-junction and a 90 degrees phase shifter. Numerical simulations show insertion losses below 0.18 dB and crosstalk lower than -20.6 dB in a 300 nm wavelength range.
