    Coherently coupled bending waveguides based on antiresonant reflecting optical waveguide (ARROW) structures are investigated. The ARROW structure can provide low-loss single-mode propagation with a relatively large core size for efficient connection to single-mode fibers. The flexible structural parameters of rib ARROW waveguides offer the possibility of optimization for various design considerations. For the total bending angles of 27.2 degrees and 91.2 degrees, the simulated system transmission efficiencies are -0.82 and -2.15 dB respectively. The corresponding device sizes are less than 10 mm(2).
