Image of FIG. 1.
FIG. 1.

(a) and (b) Cross-sectional schematic (not to scale) of the PC compared to the cavity-coupled PC. (c) Large area optical image of the cavity-coupled PC fabricated on 2 in. gold coated Si wafer. (d) Cross-sectional SEM image of the cavity-coupled PC showing 1D grating in SU8 coated with TiO, SU8 cavity, and gold layer on a Si substrate.

FIG. 2.

RCWA simulated data for one period of the PC. (a) Far-field reflection of the cavity-coupled PC for various cavity lengths. The incidence angle is θ = 0°, which corresponds to the resonance angle of the PC. (b) Far-field reflection spectrum for one cavity length (740 nm) showing the coupling compared to that of the solitary PC. (c) and (d) Near-field electric field intensity distribution for the cavity-coupled PC and the solitary PC at the resonance wavelength showing enhanced fields for the case of the coupled modes. (e) Far-field reflection spectrum for the un-corrugated structure for one cavity length (740 nm). (f) Near-field electric field intensity distribution for the un-corrugated structure at the reflection dip corresponding to λ ∼ 660 nm.

Image of FIG. 3.
FIG. 3.

(a) Experimental far-field reflection for the cavity-coupled PC at the cavity length of 750 nm and the solitary PC. The incidence angle for the laser is θ = 0° which corresponds to the resonance angle of the PC. (b) Intensity profile for PPL-Alexa 647 dye for the 3 devices (inset shown in same color scale): Cavity-coupled PC with the cavity length of 750 nm, uncoupled cavity and the PC for the cavity length of 650 nm, and the solitary PC.
