Conference publicationsProbability of realizing of multiplexers/demultiplexers with high channel numbersThe opportunity of increase in number of channels of multiplexers /demultiplexers (M/D) on a basis waveguide array gratings is considered. The analysis of the reasons limiting increase of density of channels is carried out. The role of crosstalk and losses in M/D is considered at reception of limiting characteristics. Tendencies of development M/D are formulated. Perspectives of use of hybrid circuits and cascade connection technique for M/D is shown. An atherma1 arrayed waveguide grating demultiplexer has been proposed. The trends of development of M/D are presented. |
