DS4. Experimental evaluation of the TERAWAY physical layer system, implementing optical injection locking and optical beamforming, using bulk components

This set comprises experimental results from the performance evaluation of the TERAWAY system in the physical layer, implementing bulk components. This performance evaluation focused on the optical generation of millimeter-wave signals implementing injection locking technique by means of inserting an optical frequency comb into the reference optical laser source, the fiber transmission of the optical signals, as well as the processing of this signal via an optical beamforming network.

The data set consists of multiple waveforms that correspond to 16-QAM electrical signals of 500 MBaud symbol rate, at a central frequency of 60 GHz. These waveforms were obtained directly after the photodetection stage that consists of two high-speed photodetectors in order to emulate an optical beamforming scenario. The set is separated into different folders that correspond to the injection-locked and unlocked scenarios, both in back-to-back configuration and after a 25 km transmission of the signal through an optical fiber. Each folder contains the waveforms of the electrical signals, as they were generated at the photodetection stage, under various optical power values.
