Description:
We show that the structure demonstrated by Feng et al. (Reports, 5 August 2011, p. 729) cannot enable optical isolation because it possesses a symmetric scattering matrix. Moreover, one cannot construct an optical isolator by incorporating this structure into any system as long as the system is linear and time-independent and is described by materials with a scalar dielectric function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fan, Shanhui -- Baets, Roel -- Petrov, Alexander -- Yu, Zongfu -- Joannopoulos, John D -- Freude, Wolfgang -- Melloni, Andrea -- Popovic, Milos -- Vanwolleghem, Mathias -- Jalas, Dirk -- Eich, Manfred -- Krause, Michael -- Renner, Hagen -- Brinkmeyer, Ernst -- Doerr, Christopher R -- New York, N.Y. -- Science. 2012 Jan 6;335(6064):38; author reply 38. doi: 10.1126/science.1216682.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ginzton Laboratory, Department of Electrical Engineering, Stanford University, Stanford, CA 94305, USA. shanhui@stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22223793" target="_blank"〉PubMed〈/a〉
