Here we report a simulation of bending loss of a photonic wire ring resonator. The ring resonator and waveguide core are composed of InGaAs/InGaAsP, which is isolated by an InP spacer. The waveguide core below the ring resonator could be used as a bus waveguide. The dependence of coupling coefficient on the thickness of InP spacer is calculated.
