Patent EP-0221711-A3 (EP)
IPC: H04B10/17
Filed: 1986-10-20
Abstract: An optical fiber communications system with 
Raman amplification of the signal radiation comprises a 
broadband pump radiation source (15), or, 
preferably, a multiplicity of pump radiation sources. 
The sources are selected to result in a pump radiation 
spectrum such that pump radiation intensity in the core 
of a fiber (10) is less than a critical intensity 
I c . In particular, the average intensity of pump 
radiation in a first spectral interval, centered on any 
wavelength λ p  in the pump radiation spectrum and of 
width equal to the Brillouin line width of the fiber at 
λ p , is to be less than that average intensity in the 
first spectral interval that results in conversion of 
10% of the radiation in the first spectral interval to 
stimulated Brillouin radiation. Use of a multiplicity 
of pump sources not only can reduce pump noise and pump 
depletion due to stimulated Brillouin scattering, but 
typically also can result in enhanced system reliability 
and lower cost. In a preferred embodiment, the 
invention is a soliton fiber communications system, with 
pump radiation injected at one or more intermediate 
fiber locations.

Title: Method for stabilizing an integrated-optic resonator
IPC: G02F1/03
Filed: 1987-05-16
Abstract: A circuit arrangement including a controllable optical resonator having a filter characteristic with a transmission peak arranged to pass laser radiation at a wavelength in the region of the transmission peak, wherein the resonator is positioned to receive the laser radiation at an angle such that two modes of the radiation, having respectively different polarization states, and wavelengths, are capable of propagating in the resonator. The resonator has control electrodes connected for receiving a voltage which determines the wavelength of the transmission peak of the filter characteristic and a source connected for applying to the electrodes a square-wave modulating voltage which varies between a first value which causes the transmission peak of the resonator to be substantially at the wavelength of one of the modes and a second value which causes the transmission peak of the resonator to be substantially at the wavelength of the other one of the modes. A device is optically coupled to the resonator for deriving two electrical signals each corresponding to radiation passing through the resonator in a respective one of the two modes. A device is connected for determining the phase difference between the two electrical signals and a device is connected for acting on the resonator in a manner to reduce the phase difference to zero on the basis of at least one of the electrical signals.
