Issue Date: | 1-Aug-2012 | Citation: | Martinez, J.C., Jalil, M.B.A., Tan, S.G. (2012-08-01). Giant Faraday and Kerr rotation with strained graphene. Optics Letters 37 (15) : 3237-3239. ScholarBank@NUS Repository. https://doi.org/10.1364/OL.37.003237 | Abstract: | Polarized electromagnetic waves passing through (reflected from) a dielectric medium parallel to a magnetic field undergo Faraday (Kerr) rotation of their polarization. Recently, Faraday rotation angles as much as 0.1 rad were observed for terahertz waves propagating through graphene over a SiC substrate. We show that the same effect is observable with the magnetic field replaced by an in-plane strain field which induces a pseudomagnetic field in graphene. With two such sheets a rotation of p/4 can be achieved, which is the required rotation for an optical diode. Similarly a Kerr rotation of 1/4 rad is predicted from a single reflection from a strained graphene sheet. © 2012 Optical Society of America. | Source Title: | Optics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/56139 | ISSN: | 01469592 | DOI: | 10.1364/OL.37.003237 |
