Full-duplex communications, where the transmitter and the receiver operate at the same time and at the same frequency, has become a critical research area and now we\u2019ve shown that WiFi capacity can be doubled on a nanoscale silicon chip with a single antenna. This has enormous implications for devices like smartphones and tablets.\u201d<\/p>\n<p>Krishnaswamy\u2019s group has been working on silicon radio chips for full duplex communications for several years and became particularly interested in the role of the circulator, a component that enables full-duplex communications where the transmitter and the receiver share the same antenna. In order to do this, the circulator has to \u201cbreak\u201d Lorentz Reciprocity, a fundamental physical characteristic of most electronic structures that requires electromagnetic waves travel in the same manner in forward and reverse directions.<\/p>\n<p>\u201cReciprocal circuits and systems are quite restrictive because you can\u2019t control the signal freely,\u201d says PhD student Negar Reiskarimian, who developed the circulator and is lead author of the <em>Nature Communications<\/em> paper. \u201cWe wanted to create a simple and efficient way, using conventional materials, to break Lorentz Reciprocity and build a low-cost nanoscale circulator that would fit on a chip. This could open up the door to all kinds of exciting new applications.\u201d<\/p>\n<p><!-- Link: <a href=\"https:\/\/www.sciencedaily.com\/releases\/2016\/04\/160415081512.htm?utm_source=dlvr.it&utm_medium=facebook\">https:\/\/www.sciencedaily.com\/releases\/2016\/04\/160415081512.h...m=facebook<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cThis technology could revolutionize the field of telecommunications,\u201d says Krishnaswamy, director of the Columbia High-Speed and Mm-wave IC (CoSMIC) Lab. \u201cOur circulator is the first to be put on a silicon chip, and we get literally orders of magnitude better performance than prior work.
