Highly linear integrated optical modulators are required in order to provide a distribution platform for analog Radio-over-Fiber (RoF) signals. The work outlined examines the performance of multiple bands of Generalized Frequency Division Multiplexed (GFDM) signals in a photonic link employing a linear differential drive silicon Mach-Zehnder Modulator (MZM). Performance is evaluated in terms of received Bit Error Rate (BER) and Error Vector Magnitude (EVM). In an optical back-to-back scenario, 3.3% EVM is achieved in the case where three GFDM bands modulated with 256 Quadrature Amplitude Modulation (QAM) are transmitted.

We demonstrate the performance of an InGaAs photoconductor as a heterodyne detector of optically generated mmW signals. Two continuous wave DFB lasers integrated on glass emitting in the 1.5 λs m range are used to generate radio frequency through optical heterodyning by illuminating the ultra-fast nitrogen ion implanted InGaAs photoconductive switch. The beating signal corresponding to the mmW signal is downconverted by mixing with electrical RF frequencies up to 65 GHz. This low cost and robust device as ultrafast optoelectronic mixer shows uniform performance over a wide range of detected optical beating frequencies up to 164 GHz, limited by our equipment.

We report a newly developed 45-Gbuad, 32-pixel two-dimensional photodetector array (2D-PDA) and the photodetector’s performance in free space optical (FSO) communication. With the selected 4 × 4 pixels in 32 pixels to preserve large active area, the direct coupling between high data rate FSO beam and the 2D-PDA was demonstrated to improve optical alignment tolerances. The eye diagram, bit error rate (BER), and photo-current characteristics in the range 10-45 Gbaud were evaluated for 4 ×4 pixels in plane.

A DWDM analog radio over fiber (ARoF) system connected a base band unit (BBU) to a radio remote unit (RRU). It is capable of carrying massive-MIMO, sub-6GHz and mmWave signals. It was tested using live mmWave traffic. Uplink and downlink each comprised 16 wavelengths, with directly-modulated lasers. Each wavelength capable of carrying a 2 GHz RF-bandwidth signal on a 1.5 GHz IF carrier, at RF ACLR of 40 dBc at 12 km fiber, including 3 dB ACLR improvement by offsetting the wavelength from the optical mux grid by 22 GHz. Using ARoF, no DSP is needed at the RRU. This reduces weight and power consumption on the tower compared to eCPRI, and allows the RF format to be modified as new standards emerge, without replacing or reprogramming the RRU.

This paper presents for the first time the transmission of LTE signal based-on Radio-over-Fiber (RoF) scheme by using SiGe Hetero-junction Photo-Transistor as photo-receiver. The photo-transistor is fabricated based-on the commercial bipolar transistor technology. An 850 nm single mode Vertical Cavity Surface Emitting Lasers (VCSELs) and Standard Single Mode Fiber (SSMF) are used to complete the link so that makes the total cost of the system very low. The transmission of 20 MHz bandwidth LTE signal with high modulation format is achieved. The performance of the system is evaluated through the measurement of Error Vector Magnitude (EVM) under different operation conditions of the photo-transistor (in photodiode mode, photo-transistor mode and two terminals mode). We reach an EVM below 8% for the input power of -25 dBm to -2 dBm when the photo-transistor operates under two terminals condition. This EVM value fulfills the requirements of the LTE standard for 64-QAM modulation. The stability of the system with regard temperature variation and modal noise is also presented.

An optical approach to cancel the RF self-interference using polarization multiplexed Mach-Zehnder modulators (MZMs) is presented with theoretical analysis and experimental demonstration. By using the dual-MZMs biased at inverted quadrature points, the out of phase relationship between the received interference signal and the reference signal is obtained. Through adjusting the delay time and amplitude of the reference signal in optical domain, the matching conditions for the RF self-interference cancellation are implemented. Only one laser source is utilized and the coherent beat noise between the optical carriers from the same laser source is prevented by the polarization multiplexing. The cancellation experiments of RF signals at 5 GHz and 8 GHz are conducted. The self-interference cancellation performance for single frequency and bandwidth of 5 MHz and 10 MHz are investigated.
