@inproceedings { , title = {Parity-time chain of whispering-gallery mode resonators}, abstract = {The paper analyses the dispersion characteristics of an infinitely long PT chain made of whispering gallery resonators with gain/loss modulation. The results show that the appearance of the threshold breaking point depends not only on both of coupling and gain/loss modulation but also on the Bloch phase. The Bloch phase is seen as an additional parameter that can reduce or even completely eliminate PT-breaking threshold.}, conference = {META15, the 6th International Conference on Metamaterials, Photonic Crystals and Plasmonics}, note = {Can't find ISSN TJJ 24/08/2017}, organization = {New York, USA}, publicationstatus = {Published}, url = {https://nottingham-repository.worktribe.com/output/759642}, year = {2015}, author = {Phang, Sendy and Vukovic, Ana and Creagh, Stephen and Benson, Trevor M. and Gradoni, Gabriele and Sewell, Phillip D.} }
