We report a beamforming architecture that leverages on increased precision provided by the PAA configuration previously presented but free from beam squint limitation. This is achieved by inserting a precompensating OTTDL stage prior to the configurable delay stages.

Deep learning is a powerful tool for enhancing performance and increasing the functionalities of a system. However, it is challenging to use deep learning to enhance hardware-based photonic systems because a large dataset that covers the whole operation range of each device is needed for achieving an accurate model. However, not all devices in a system can be controlled automatically, making the data collection process challenging and time consuming. In this letter, we use an instantaneous microwave frequency measurement (IFM) system to demonstrate the use of generative adversarial network (GAN) in deep learning platform for data augmentation. With GAN, only 75 sets of experimental data are needed to collect manually from the IFM system. The GAN augments the 75 sets of experimental data into 5000 sets of data for training the model, effectively reduces the amount of experimental data needed by 98.75%, and reduces frequency estimation error by 10 times.

Covert wireless communication assisted by optical frequency comb (OFC) has already been presented, but its denoise capacity is restricted by the OFC properties. A novel, low-cost covert wireless communication system is proposed and demonstrated. In the proposed approach, original data are spread and buried by the noise to ensure high covertness, and then are effectively recovered by analog frequency convolution using the OFC and the cloned OFC generated by an optical frequency shifter. A same signal to noise ratio (SNR) enhancement can be achieved by employing half of the optical comb lines, which alleviates the requirement of OFC generator. 400 comb lines provide 800 comb channels, so that 29 dB SNR rise is achieved for the microwave signal with a 16 GHz bandwidth and a 20 Mbit/s data rate, which is hidden below the in-band noises by 20 dB or even 29 dB in both the frequency and time domains.

Simultaneous transmission of high-speed data and high-power energy in optical networks is merging radio-over-fiber (RoF) and power-over-fiber (PoF) concepts. In this work, we present an approach to evaluate the analog performance of RoF-PoF systems, based on figures of merit used in microwave photonics. Different optical links are proposed to transmit and receive RF signals remotely, while using the same fiber to supply power to electronic sensors. We compare measured values with theoretical predictions in two experimental setups. Both employ a 1480 nm power signal and a 1550 nm data signal propagating together over a 10 km single-mode fiber (SMF). Analytical results are in good agreement with measurements, as long as power level does not exceed a specific threshold, when system instabilities arise. Optical power delivered to the optical-electrical converter is sufficient to feed low consumption devices, proving the effectiveness of such approaches in remote applications.

In this paper, we present a theoretical framework for investigating losses and thermal fluctuations in a Josephson traveling-wave parametric amplifier (JTWPA). Our model is based on a discrete-mode Hamiltonian which includes a four-wave-mixing process and system-reservoir interactions. From this Hamiltonian, we derive a quantum master equation that describes the lossy Josephson-junction-embedded transmission line. The resulting equation of motion for the reduced density operator is applied for evaluating the average photon number in the signal mode. We present an analytic solution for the case of a dispersionless transmission line, where the phase-modulation effects can be neglected, and evaluate the photon number spectrum of a JTWPA structure with parameters from the literature. The quantum master equation is especially advantageous for a direct treatment of the expectation values of the photon number, in comparison to other strategies.

In this paper, a compact integrated CMOS phase locked loop (PLL) is proposed to lock the drifting beatnote generated by heterodyning two optical lasers/comb tones. The integrated PLL is fabricated in TSMC 65nm CMOS process. It takes dc power of 9.8 mW and occupies an area of 0.67 mm2. When heterogeneously integrated with photonic chips, stable and high-power millimeter wave (mm-wave) could be generated in a compact packaging for radio-over-fiber communication systems and antenna remoting. A prototype of the integrated PLL is demonstrated and measured with the beatnote locked at 1.12 GHz.

Two microwave photonic links (MPLs) with increased transmission capacity based on coherent detection and digital signal processing are proposed. In the first MPL, two microwave vector signals at the same microwave carrier frequency are applied to a dual-drive Mach-Zehnder modulator (DD-MZM) to modulate the two signals on an optical carrier. After transmission over a single-mode fiber, the optical signal is received at a coherent receiver. To recover the two microwave vector signals, a DSP algorithm is developed. Full recovery of the microwave vector signals free from the joint phase noise between the transmitter and the local oscillator laser sources is realized. In the second MPL, the DD-MZM is replaced by a dual-parallel DD-MZM, to which four microwave vector signals are applied. Again, a DSP algorithm is developed. Full recovery of the microwave vector signals free from the joint phase noise is realized. For the MPLs, error-free transmission is experimentally demonstrated.

High-resolution imaging of near field targets is experimentally demonstrated using a broadband microwave photonic array radar that is implemented by photonic frequency quadrupling and de-chirping. A scanning time delay (STD) compensated digital beam forming (DBF) method is adopted to deal with the beam squint and broadening problem in broadband radar imaging. In the experiment, a 1×16 microwave photonic array radar having a bandwidth of 8 GHz is implemented. By using the STD-compensated DBF method, high-resolution imaging of near-field targets is achieved with obvious suppression of grating lobes and accurate beam correction.
