We present a design for a subwavelength C-shaped optical waveguide with a 90 ° junction that efficiently transports light while maintaining tight confinement with an exit spot size of λ 7 . Finite-difference time-domain simulations of perfect electric conductors and Au C-aperture waveguides are performed for optical frequencies. A design resonant near 780 nm is presented, with a spot size of 107 nm × 107 nm and an energy density enhancement factor of 10 for a bent waveguide of total length 1.4 μ m .
