This article [Opt. Eng. 50, 084601 (2011)] was originally published on 28 Jul 2011 with numerous typesetting errors. To correct these errors, the following changes were made:

The title of Section 2.1 was changed to “Transfer Matrix Formalism.”

In Section 2.2, the order of the first two paragraphs was switched, which changed the callout numbers for Figs. 3 and 4. The captions for Figs. 3 and 4 were also switched.

The last line before Eq. (25) was changed to “Therefore, the overall transmittance of TRR for FSR = 605 GHz can be written as below.”

Figure captions 7 and 9 were edited to include part label (c).

For clarity, the second to last sentence in Section 6 has been edited to read, “In the first case of design, cross talk levels obtained by simulation is less than −10 dB, and resonance loss is around −13 dB, which closely agree with the limits stipulated in Ref. 4.”

The manuscript was corrected online on 8 Aug 2011. The article appears correctly in print.
