Resumo
This work shows an Erbium doped-fiber Laser with many frequencies and many
operation regimes based on integration of two paired arrayed waveguide gratings
(AWGs) into a ring cavity. The AWGs are highlighted, since 2000, as key technology
for multifrequencies lasers for optical communications, spectroscopy, image, astronomy
and others applications. Fundamentally, gratings work splitting waveguide signal and
since insertion in the cavity they allow simultaneous operating of tens of wavelength.
We explore each one of these wavelength withing Erbium gain region, doing channels
in different regimes of operation. These regimes may be continuous or pulsed. The
advantage is that each channel may be modulated independently. Simultaneous
operation with high repetition rates at 10 and 40 GHz were demonstrated, as continuous
wave. The laser is stable, versatile and multifunctional. It is possible that more
operating regimes, as passive mode-locking, be explored. We showed by this work
efficient way to passive mode-locking by carbon nanotubes as saturable absorbers.
Soon, the passive mode-locking is a potential regime for the demonstrated laser. As the
new bi-dimensional materials, that look efficient for passive mode-locking and in the
future, hybrid mode-locking, as graphene and black phosphor.
