Publisher: | IEEE | Source: | 16th International Conference on Transparent Optical Networks (ICTON) -- JUL 06-10, 2014 -- Graz, AUSTRIA | Series/Report no.: | International Conference on Transparent Optical Networks-ICTON | Abstract: | We propose a simple realization of a 2-dimensonal (2D) PT-symmetric photonic structure: a honeycomb arrangement of alternating cylinders with gain or loss in a dielectric background. The structure provides a periodic modulation of the refractive index on the wavelength scale, which combined with an anti-symmetric gain/loss distribution on the same scale, leads to non-reciprocal light coupling at resonance frequencies. Numerical simulations show asymmetric right-left transmission of light beams. | URI: | https://hdl.handle.net/20.500.11851/6317 | ISBN: | 978-1-4799-5601-2 | ISSN: | 2162-7339 |
