Abstract

Optical frequency combs forming in microring cavities are revolutionising photonics’ technologies, thanks to the temporal dissipative solitons [1, 2]. Important novel directions in this active research field are expected if dissipative solitons are formed in multi-dimensional geometries [3], as these support new types of solitons [4] and display special physical phenomena [5] with no direct one-dimensional counterparts. Here, we demonstrate an unexpected new type of stable two-dimensional nonlinear wave, namely the Photonic Snake [cf. Figs.1(b)-(g)], which exists in cylindrical microcavities with normal dispersion and continuous diffraction along its axis.
