Abstract :
90deg bent hollow waveguides with distributed Bragg reflectors (DBR) in silicon substrate are proposed. The air core was embedded by Si3N4/SiO2 multilayer. The two-dimensional (2-D) finite-difference time-domain (FDTD) method is used to simulate bending transmission efficiencies of the 90deg-bent waveguides. The lowest 90deg bending loss is around 0.8 dB. This waveguide can be used in integrated planar light wave circuits.
