Stable propagation of TE and TM-polarized solitons is accompanied by attenuation of all other modes, i.e., the waveguide features properties of conservative and dissipative systems. If the linear spectrum of the waveguide possesses exceptional points, which occurs in the case of TM polarization, an originally focusing (defocusing) material nonlinearity may become effectively defocusing (focusing). This occurs due to the geometric phase of the carried eigenmode when the surface impedance encircles the exceptional point. In its turn, the change of the effective nonlinearity ensures the existence of dark (bright) solitons in spite of focusing (defocusing) Kerr nonlinearity of the core. The existence of an exceptional point can also result in anomalous enhancement of the effective nonlinearity. In terms of practical applications, the nonlinearity of the reported waveguide can be manipulated by controlling the properties of the absorbing cladding."}],"intvolume":"       119","publist_id":"6481","external_id":{"isi":["000405718200012"]},"isi":1,"year":"2017","date_published":"2017-07-18T00:00:00Z","ec_funded":1,"project":[{"_id":"25681D80-B435-11E9-9278-68D0E5697425","grant_number":"291734","name":"International IST Postdoc Fellowship Programme","call_identifier":"FP7"}],"status":"public","publication":"Physical Review Letters","type":"journal_article","date_updated":"2023-09-26T15:39:46Z","_id":"939","publisher":"American Physical Society","doi":"10.1103/PhysRevLett.119.033905","article_processing_charge":"No","quality_controlled":"1","main_file_link":[{"url":"https://arxiv.org/abs/1706.04085 ","open_access":"1"}]},{"year":"2016","publist_id":"6030","project":[{"_id":"25681D80-B435-11E9-9278-68D0E5697425","name":"International IST Postdoc Fellowship Programme","grant_number":"291734","call_identifier":"FP7"}],"status":"public","publication":"Physical Review A - Atomic, Molecular, and Optical Physics","ec_funded":1,"date_published":"2016-10-13T00:00:00Z","acknowledgement":"The work was supported by the NSF through a grant for the Institute for Theoretical Atomic, Molecular, and Optical Physics at Harvard University and the Smithsonian Astrophysical Observatory.
