The spectrum shows a stop-band of 7nm, an extinction of 24dB, and a Q of 7,000.}, URL = {http://ieeexplore.ieee.org/xpl/articleDetails.jsp;jsessionid=bgHFQn1TjprVj2Mq5thJVvlwH1t4Yh4FbLGGJfRLYjJssGNM3CyT!-1710983194?arnumber=6324092&contentType=Conference+Publications}, author = {Wei Shi and Xu Wang and Charlie Lin and Han Yun and Yang Liu and Tom Baehr-Jones and Michael Hochberg and Nicolas A.
