Project Overview
The integration of optical components and functions into a large scale PIC shows significant benefits when it is integrated into an optical communication system. It enables significant power, space and cost savings, new functionality and so new significant increasing transmission capacity of communication systems. In satellite communication multiple channels are being multiplexed to increase the throughput. Optical Tx using QPSK and DP-QPSK are commercially available. Multilevel modulation techniques like mQAM are also being used. Polarization modulation is a third dimension which can be included to increase the overall baud rate.In the present research it is aimed to design Optical Tx and Rx chips using PICs employing multilevel modulation with amplitude, phase and polarization. Using this technique multiples optical channles with different modulation can be sent over single channel to achieve terabytes of data over single channel.
Achievements
The project being undertaken by ISRO in collaboration with academia is directly or indirectly beneficial to the society.
