Abstract :
This paper presents a new phenomenon in the context of delayed (electro-)optical systems, hyperchaotic breathers, which are characterized by strongly hyperchaotic oscillations at a ns-timescale, whose amplitude envelope is periodically "breathing" at a slower μs-timescale. Experimental timetraces of the hyperchaotic breathers are obtained and compared with numerical timetraces.
