Abstract: The amplifier (1) is made up of two active fibre or guide amplifiers (2, 3) placed respectively before and after a gain clamped semiconductor amplifier (4), brought to stimulated emission conditions, which acts as pump radiation source for the two active fibre or guide amplifiers (2, 3).

Abstract: The signal to be controlled is sent along an optical fibre (3) by means of a wavelength tunable laser (2) whose emission wavelength may be varied as a fu nction of a possible phase variation in the received signal with respect to a refer ence phase. At the receiving end of the fibre a control signal is generated by extractin g a fraction of the power associated with the received signal and sending such fraction back towards the transmitting end, and at the transmitting end the phase of said fraction is compared with that of the original signal and the tunable laser is driven (2) in such a way as to transmit at a wavelength such that the clock information reaches the receivi ng end with the reference phase.

Abstract: Within an optical ATM node, an ATM cell to be synchronized is sent into a segment of pre-determined length of an optical fibre with a high time dispersion (FD), after having been associated, in a tunable wavelength converter (CL), to an optical carrier with a wavelength that is different from that with which the cell itself was received and such that, as an effect of the transit the fiber (FD), the cell reaches the input side of a switching element (Em1...Emh) of the node (NC) at a predetermined instant.

Abstract: The method and the device obtain stabilization by locking the emission wavelength of the laser to an absorption line of a gas. The radiation emitted by the laser is guided through the environment containing the gas to the detector along an optical waveguide giving rise to an evanescent field that propagates outside the waveguide (Figure 1).
