Abstract:
An error was made in the calculation of the photonic crystal
mode volume. Fixing this error increases our mode volumes by a factor of
two and makes our claim of highest
Q
/
V
invalid.

In our article [1], we state that the mode volume of the 1D photonic crystal nanobeam cavities
is 0.27(
λ
/n)
3
. This value appears in the caption for Fig. 1, in the last paragraph of section 4
a
nd in the conclusion. Recently, it was discovered that a factor of two error was made in the
calculation of cavity mode volume. This error results in an increase in the mode volume of
these cavities to 0.54(
λ
/n)

.
W
e make the claim in the last paragraph of the introduction, at the end of section 4
and in the conclusion that we have observed the highest
Q
/
V
ratio as of the date of
publication. Using this new mode volume, and our reported highest
Q
of 75,000, our
calculated
Q
/
V
ratio becomes 139,000. This value is no longer larger than the
Q
/
V
ratio of
173,000 reported by the group of De La Rue [2], making our claim invalid.
