Sub-THz and THz Photonic generation with continuous tunability using gain switching based optical frequency comb generators and n-i-p-n-i-p superlattice photomixers

In this work we present a compact and versatile way to generate sub-THz and THz signals using an OFCG based on a Photonic Local Oscillator responsible to generate the two wavelengths to be mixed in the photomixer based on a Gain Switching (GS) Scheme and the use of Phase Modulation; and n-i-p-n-i-p superlattice photomixers. The proposed scheme is able to cover a wide span with continuous tunability. The description of the different components of the system (Photonic Local Oscillator and Photomixer) is covered as well as some preliminary data.
