Photonic-Crystal Cavity Arrays in PDMS:
The nanopillar photoniccrystal cavities are arran
ged in arrays with varying pitch and diameter in
order to fine tune the resonant wavelength and
Q
factor. Each array contains 4 rows and 6 columns of
devices. In each row, the radius is varied between
0.152
a
and 0.22
a
(where
a
is the interpillar pitch). In
each column, the interpillar pitch is varied betwe
en 324 nm and 342 nm. This variation in pitch
corresponds to resonant wavelengths between 950 nm
and 1000 nm according to the normalized
frequency calculated from FDTD simulations (λ =
a
n
,
where
ω
n
= 0.342). Fig. S2 shows a darkfield
optical microscope image at 50
×
magnification of an array in PDMS with the inset s
howing a single
device at 150
×
magnification. Additional rows for other experimen
ts (labeled A) are visible but not
reported on in this paper.
