(a) A sketch of the design where the interface between SNB, PhCWG, and RWG is shown. (b) Evolution of the normalized transverse-electric guided mode at the interface between SNB and RWG. The arrow indicates the input port used for calculation of the transmission in the structure. (c) and (d) Normalized transverse-electric guided mode profile at the entrance of the SNB and RWG, respectively.
SEM image of the fabricated devices at (a) entrance of a RWG with width and (b) interface of the suspended and ridge structures.
Plot of the transmission versus wavelength for a (a) RWG (the blue and the red horizontal lines are the fit to the experimental data and the average transmission for the measured RWG, respectively). The inset illustrates a sketch of the system measured and (b) RWG-PhCWG-RWG system. The left inset shows the RWG-PhCWG-RWG transmission over a broader spectral range and the right inset illustrates a sketch of the system measured. The red horizontal line indicates the average transmission for the measured RWG-PhCWG-RWG system.
(a) PL spectra of a QD in an L3 cavity coupled in-line to a PhCWG and then to a RWG, recorded at different temperatures. The curves are offset for clarity. The inset shows the SEM image of the PhCC (b) Time-resolved PL of the dot indicated by the arrow at 25 K (on-resonance, red triangles) and 38 K (off resonance, blue rectangles) collected from the side. The PL decay of a dot in the bulk (green circles, measured from the side) is shown for comparison. The decay curves have been normalized and the mono-exponential fits (grey lines) are obtained after convolution with the measured instrument response function (IRF) (black triangles).
Normalized coincidence counts of the QD indicated by arrow in Figure 4 at 25 K coupled from the side to a Hanbury Brown-Twiss set-up.
