Figures

Image of FIG. 1.
FIG. 1.

(Color) (a) shows a diagram of a conventional slotted waveguide, as well as the modal pattern near . The mode is plotted with contours of 10% in , assuming of average power flow. (b) shows a scanning electron microscopy (SEM) micrograph of a fabricated slotted waveguide, in this case being used for a ring resonator.

Image of FIG. 2.
FIG. 2.

(Color) (a) shows a vertical cross section of waveguide design 1 for a mode at . The mode is plotted in contours of 10% in , assuming of average power flow. (b) shows a horizontal cross section of waveguide design 1, with the cross section taken midway through the waveguide. The mode is plotted with contours of 10% in , assuming of average power flow. (c) shows the effective index as a function of wavelength for the two segmented slotted waveguide designs, as well as the normal slotted waveguide.

Image of FIG. 3.
FIG. 3.

(Color) (a) shows typical normalized insertion losses of devices in three sizes (33, 4000, and of segmented slotted structures) in dB vs. wavelength in nm. With the periodicity of design 2, corresponds to 32 000 contact pairs. A nonslotted waveguide control loop device is also presented in the same plot. (b) shows a top view SEM micrograph of a segmented slotted waveguide device. (c) shows two angled view SEM micrographs of the devices exposing their cross-sections.
