Abstract
We correct two small errors in our publication [Opt. Express 21, 22441 (2013)].

First, Eq. (3) in our publication [1] has a typographical error, with a squared factor missing in the denominator. The correct version reads as follows:
Second, in [1] we assigned the mode families investigated as TM1 and TM2. Subsequent measurements show that these modes are actually transverse electric, TE1 and TE2. A new version of Fig. 2 showing simulated mode profiles and dispersion for the TE modes is given below. The measured dispersion values and the conclusion that the investigated devices have normal group velocity dispersion remain unchanged.References and links
