In this field, photonics is used to transform and transfer digital content. First, the contents are converted to a format that can be compressed and transferred at high speed through the use of data communication networks (optical fiber) to finally return to be converted to a format that can be used by the user.

During these steps, the use of photonics has become crucial: the use of lasers and modulators for transforming electrical information light, the use of optical cable and amplifiers for transferring data, and finally the optical receivers that convert optical signal back to electrical signals that can be processed for the end use.
