Microphotonics employs [photonic crystals]?, non-conducting materials that reflect various wavelengths of light almost perfectly. Such a crystal can be referred to as a [perfect mirror]?. Other devices employed in microphotonics include micromirrors? and [silicon waveguides]?. These tools are used to 'mold the flow of light', a famous phrase for describing the goal of microphotonics.
Currently microphotonics technology is being developed to replace electronics in devices optical router would eliminate this bottleneck, speeding up the network. [Perfect mirrors]? are being developed for use in fiber optic cables.
