3D-Photonic Crystal Add-drop Filter, yet another new slot added to technology. It is developed by a team led by Rana Biswas, which enhances transmission through multiple channels along optical fibres.
This can be rightly said as a milestone in the development of optical networking and communication to eliminate various hinders involved in optical transmission links, resulting in flawless data transmission for the Internet and other fibre-based telecommunication systems.As sai d by Biswas,
“There are up to 160 wavelength channels travelling through an optical fibre at the same time. That means a lot of dialogue is going on simultaneously”.
Biswas, also explained that as information is transfered over multiple channels, it is necessary to periodically drop individual wavelength channels. At the same time, able to add data streams into the empty wavelength channels.
It is also said that when data is transferred along multiple channels it becomes necessary to receive only one signal at a point.
