Abstract

While the application of optical and photonic technologies in the communications, computing, medicine and industrial manufacturing has been growing rapidly, the miniaturization of these technologies has been slow due to the limitation on the diffraction. However, the developments of nanoscale components and guiding methods are continuing with a rapid pace. Since waveguiding is a fundamental issue in communication, we briefly examine the current state of nanoscale waveguiding with their application in communication which are the building blocks of ultra-high density photonic devices. Finally, we conclude that the QD waveguide may be an effective and an alternative means to transmit light.
