Over the last few years wireless link data traffic has drastically increased due to a change in the way today's society creates, shares, and consumes information. Millimeter-waves (30–300 GHz) have a great advantage due to the wide bandwidths available for carrying information, enabling broadband wireless communications. Photonics is a key technology for millimeter wave signal generation and to develop...
We present two different on-chip photonic integrated circuit (PIC) structures for continuous-wave generation of millimeter and terahertz waves, each one using a different approach. One approach is the optical heterodyne method, using an on-chip arrayed waveguide grating laser (OC-AWGL) which is capable of generating a carrier at 110 GHz within the F-Band (90 GHz–140 GHz). The other structure provides...
This paper describes the advantages that the introduction of photonic integration technologies can bring to the development of photonic-enabled wireless communications systems operating in the millimeter wave frequency range. We present two approaches for the development of dual wavelength sources for heterodyne-based millimeter wave generation realized using active/passive photonic integration technology...
Sub-terahertz and terahertz frequencies can be generated by optical heterodyning of two wavelengths. Two laser modes, generated with a Photonic Integrated Circuit which integrates an Arrayed Waveguide Grating, are employed to create terahertz frequencies. The wavelength difference of the two optical modes defines the frequency of the generated wave, which can be discretely tunable by selecting different...
