Furukawa Electric has succeeded in reducing the chip size in next-generation silica-based optical waveguide circuits(note 1) (hereinafter called, PLC) to less than one tenth of the size of conventional chips. This has made it possible to realize the high-density integration of the circuits.
Two presentations related to this technology will be given at OFC2014 to be held in March this year, the largest international conference in the optical communications sector in the world. These presentations will be on “Ultra-small coherent mixers” and “Low loss connection technologies for super high refractive index PLC (hereinafter called “super high Δ PLC”).”
In recent years, the arrival of smartphones and the spread of moving picture distribution and social networks, etc., have resulted in an explosive increase in communications traffic. In order to realize this advanced information-oriented society, it is necessary to realize ultra-high speed and large-capacity transmission.
The introduction of the optical digital coherent system(note 2) is being accelerated as a step to achieve this ultra-high speed and large-capacity transmission and there is a requirement for the provision of optical components and terminal equipment to achieve this. There are also demands for more compact, higher functioning and lower costing optical devices and in order to satisfy these demands, it is becoming necessary to develop innovative technology that goes beyond the design limits for conventional...
