DESCRIPTION:Dissipative solitons in optical microcavities have attracted m
 uch attention in recent years due to their applicability to frequency comb
  technologies. A frequency comb can be thought of as an optical ruler with
  unprecedented precision. In this talk I will address the problem of gener
 ating soliton-comb in a microresonator made of a material characterised by
  quadratic nonlinearity. Such nonlinearity allows the so-called process of
  second harmonic generation\, hence the potential formation of a soliton-c
 omb in two separated regions of the light spectrum. The difference between
  group velocities of first and second harmonic comb is investigated theore
 tically and shown to be a key parameter to ensure the existence and the st
 ability of second harmonic generated soliton-combs. Finally\, the transiti
 on from soliton to dissipative breathers and to chaotic regimes will be di
 scussed.\n&nbsp\;
