Schematic of the proposed CL7 cavity in (a) with vertical and horizontal cross sections along the structure. The near-field spectrum, calculated at the center of the cavity, is presented in (b) where the resonance of the fundamental mode is shown to occur at with a quality factor of Q_CL7 = 1590. The amplitude of the two transversal electric field components at this resonance are given in the xOy plane located 15 nm above the InP membrane in (c,d). The white lines are iso-amplitude contours of the vertical component of the magnetic field (H_z) (e) Spatial distributions of the two transversal electric field and the longitudinal magnetic field components (logarithmic scale) at resonance in a vertical plane (xOz) passing by the center of the CL7.
