Figure 4: (a) Spectra before and after including a 26.2 μm waveguide cavity. Coupling efficiency into the waveguide is plotted for “before cavity’’ and transmission is plotted for “after cavity.’’ (b) Dependency of quality factor and peak transmission on the waveguide cavity width. Parameters used: grating parameters same as above, m, m, nm, m, nm, .
