Abstract: A fibre Bragg grating (34) is used to stabilize the intensity and frequency fluctuations of a diode laser (26). The diode laser is connected with an opto-mechanical apparatus to the fibre which contains the grating.  The grating is formed in the guided-mode region of the optical fibre (32).  The wavelength of maximum grating reflectivity is selected to lie near the maximum of the diode laser gain bandwidth.  The output facet of the diode laser has a reflectivity approximately equal to or greater than that of the fibre Bragg grating.  The magnitude and bandwidth of the grating reflectivity stabilizes the diode laser output without appreciably reducing the optical output power from the end of the fibre.  The bandwidth of the optical spectrum of the diode laser is selected depending on the distance of the grating from the diode laser.

Filed: 1995-09-12
Abstract: In a call and connection separated network a method of providing distribution of resources of a physical network (1-11) among different logical networks (LN1-LN3) which are using the physical network for establishing connections.  All of the physical resources of the physical network are mapped network onto a single logical network description that will comprise nodes (F1-F3), trunk groups (17-20) interconnecting the nodes, and resource pools. The different logical networks are created by routing tables (24, 27) located at each of the nodes. The routing tables are provided with a fixed maximum percentage figure (MAX SEIZURE) relating to the maximum amount by which an individual logical network is allowed to use a common resource thus distributing said resources between the different logical networks. By assigning an individual maximum percentage figure to each of the logical networks and in so doing observing the sum of the maximum percentages for all logical networks it is possible to create complete resource separation of the resource or competition for the resource among the logical networks.
