Title: Optical communications system using raman repeaters and components therefor
Inventor: HICKS JOHN WILBUR
IPC: H04B10/58
Filed: 1984-05-11
Granted: 1989-10-19
Abstract: An optical fiber communication system for transmitting information-bearing optical signals over an optical fiber transmission line includes a signal generator coupled to the transmission line for introducing information-bearing optical signals thereonto, preferably as wavelength modulated signals, and one or more optical amplifiers for periodically, collectively amplifying the transmitted signals to overcome the effects of attenuation. Wavelength modulation is achieved by altering the resonant characteristics of an optical resonator, optically coupled to a gain medium so as to provide an output that varies between a first and second wavelength. The optical amplification is achieved by injecting, preferably via lateral optical fiber couplings, pumping beams into the optical fiber so as to effect an increase in the amplitude of the information-bearing signals by stimulated Raman scattering.

Abstract: A catalyst such as an enzyme is contained in an asymmetric membrane between two immiscible liquid streams. A catalytic reaction is carried out by introducing a reactant to one stream and removing a product from the other stream. When the catalyst becomes deactivated, the membrane can be recharged with catalyst by displacing the deactivated catalyst and introducing fresh catalyst. The membrane has a skin layer that has pores sufficiently small so as to prevent leakage of the catalyst and a highly porous region that contains the catalyst. Insolubility of the catalyst in the immiscible liquid prevents loss of the catalyst for the highly porous region.
