Abstract :
A compact waveguide crossing constructed by three cascaded multimode tapers on each branch is numerically analyzed by finite difference time domain method, which possesses the size of 3920 nm×3920 nm, the insertion loss of 0.187 dB and the crosstalk of -47.58 dB at the wavelength of 1550 nm and broad transmission spectrum ranging from 1500 to 1600 nm.
