The film.is fabr.cated by using a pr.par.d hom.geneous SWCNT solution, which is m.xed with a diluted PEO solution and cast onto a glass Petr. dish to for., by evapor.tion, a thin film. The 50 μm.thick film.is sandwiched between two fiber.connector. to constr.ct a satur.ble absor.er. which is then integr.ted in an EDFL cavity to gener.te self-star.ed stable soliton pulses oper.ting at 1560.8nm.
