Image of FIG. 1.
FIG. 1.

(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.

Image of FIG. 2.
FIG. 2.

SEM image of the fabricated devices at (a) entrance of a RWG with width and (b) interface of the suspended and ridge structures.

Image of FIG. 3.
FIG. 3.

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.

Image of FIG. 4.
FIG. 4.

(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).

Image of FIG. 5.
FIG. 5.

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.
