Room-temperature spectra of modified L3 PhC nanocavities with (top curve), 0 nm (middle curve), and (bottom curve). Curves are shifted vertically for clarity. Inset shows a SEM image of the PhC nanocavity with . Dashed circles indicate the modified holes.
Broadband room-temperature spectra of L3 nanocavity with , reference PhC membrane, unpatterned Si membrane, and reference Cz-Si sample. Excitation power is in all cases. The sharp drop at 1620 nm, common to all spectra, is due to the detector cutoff. The top panel shows the calculated spectrum, including cavity resonances and PhC band edges.
(a) intensity, Q-factor, and (b) resonance wavelength of the L3 cavity with as a function of the excitation power.
(a) Temperature-dependent PL intensity of the modified L3 nanocavity for on-resonance wavelength (open circles) and off-resonance by (full circles). (b) Arrhenius plots of the high-temperature PL tails for on-resonance (open circles) and off-resonance (full circles) wavelengths. Dashed lines are linear fits to experimental data.
