Abstract:
1. An optical transmission system for supporting the propagation of femtosecond optical pulses, the optical transmission system comprising a first section of fiber supporting the propagation of a chirped optical pulse, the first section of fiber exhibiting a first effective area A a first graded-index fiber lens coupled to the output of the first section of fiber; a second section of fiber coupled to the output of the first graded-index fiber lens, the second section of fiber exhibiting a second effective area A a second graded-index fiber lens coupled to the output of the second section of fiber; and an optical transmission fiber coupled to the output of the second graded-index fiber lens, wherein the second graded-index fiber lens provides mode matching between the second section of fiber and the optical transmission fiber such that the optical transmission fiber supports the propagation of a femtosecond optical pulse.
