ABSTRACT: Summary form only given. Wavelength-controllable components, such
as laser sources, which can operate at several selectable wavelengths,
can be very attractive for many applications, especially for dynamic
wavelength division multiplexing (WDM) networks in fiber optic
communication. It is difficult to obtain fiber lasers and even diode
laser-based systems with several wavelengths, which can be tuned and
selected at high speeds. We report on wavelength selectable fiber and
diode lasers, which can operate at each of several chosen wavelengths,
with the possibility of switching between them at high speeds. The
obtained selection time was ~5 ns for the diode laser system and ~150 ns
for the fiber laser. The method is based on mode-locking or
cavity-resonance-operated wavelength selection (CROWS). It is done by
applying the suitable mode-locking frequency of a multiple-length fiber
laser cavity, formed by multiple successive fiber grating reflectors,
each with a different Bragg wavelength. It allows selection and high
speed switching between these wavelengths. Such lasers can be useful for
dynamic wavelength division multiplexing (WDM) in fiber optic networks
