Multicore single-mode soft-glass optical fibers

The work presents recent developments of chosen aspects of optical fiber te chnology at the Research Production Department of Fiber Optics (FOD) at Bia glass Co. The modified multicrucible (MMC) technology of optical fibers, re ferred shortly to, throughout this work, as the MMC process was used to obt ain several kinds of usable optical fibers for sensors and functional compo nents of fiber microoptics. The MMC fibers, which are analyzed in this pape r, are triple-core, double-core and twin-core, also quadruple-core ones. Th ese fibers belong to the broader family of multicore optical fibers (MOFs). Such fibers introduce a few of new possibilities to the transmissive or se nsory photonic system design: wave and core multiplexing, internal in-fiber interference and multichannel property. These features are subject of rese arch in this work. Some of the unique properties of MOFs seem to have been shown (calculated and measured) for the first time.
