“…stationary radar and industrial monitoring, while embedded sensing and mobile communications require extreme integration. For the vast majority of applications, however, the required sizes range from a few cubic millimeters to a few tens of cubic millimeters, necessitating co-packaging or complete integration [47,63,64]. Similarly, the constraints in regards to energy consumption are highly dependent on the environment in which the application will be employed, with the constraints for stationary applications being less stringent than for mobile, remote or autonomous devices [41].…”

Technological innovation with millimeter waves (mm waves), signals having carrier frequencies between 30 and 300 GHz, has become an increasingly important research field. While it is challenging to generate and distribute these high frequency signals using all-electronic means, photonic techniques that transfer the signals to the optical domain for processing can alleviate several of the issues that plague electronic components. By realizing optical signal processing in a photonic integrated circuit (PIC), one can considerably improve the performance, footprint, cost, weight, and energy efficiency of photonics-based mm-wave technologies. In this article, we detail the applications that rely on mm-wave generation and review the requirements for photonics-based technologies to achieve this functionality. We give an overview of the different PIC platforms, with a particular focus on hybrid silicon photonics, and detail how the performance of two key components in the generation of mm waves, photodetectors and modulators, can be optimized in these platforms. Finally, we discuss the potential of hybrid silicon photonics for extending mm-wave generation towards the THz domain and provide an outlook on whether these mm-wave applications will be a new milestone in the evolution of hybrid silicon photonics.

“…By adjusting the frequency of the TLS, both laser modes are separated with a difference frequency of Δf. To ensure an identical polarization state of the two laser sources, a polarization controller (PC) is applied after the TLS, which is essential for an efficient mm-wave generation [7], [8]. The dual-laser signal is amplified by an erbium-doped fiber amplifier (EDFA) and further filtered by an optical band pass filter (OBPF) to reduce amplified spontaneous emission (ASE) noise of the EDFA.…”

In this paper, we report on photonic millimeter-wave generation based upon optical heterodyning as well as external modulation for ultra-broadband and low phase noise operation. Using a special broadband high-power pin photodetector (PD) we demonstrate wideband (W-band) and broadband (DC110GHz) optical millimeter-wave generation. For wideband operation, we utilized a wavelength-tunable dual-laser setup. Here, the PD output was coupled to a rectangular WR10 waveguide output port and a subsequent limiting W-band amplifier. With this setup, we achieved wideband tunability within the W-band from 69GHz to 112GHz with a maximum output power variation below 3dB and a saturated output power of 0dBm. The 1dB compression point is about -4dBm and the dynamic range is about 32dB. For broadband operation, we have coupled the photodetector to a coaxial W1 output port allowing continuous frequency tunability from DC to 110GHz with a maximum power penalty of only 6dB and a maximum output power of -3dBm. For generating low phase noise optical mm-wave signals, we have used an external modulator instead of the dual-laser. For an optically generated 100GHz signal we have achieved a phase noise level of about -70dBc/Hz at 10kHz offset.
