Optoelectronic down-conversion and phase locking of mm-wave and THz optical beatnotes using interleaved combs is presented. The generation of the required combs using either nonlinear modulation or four-wave-mixing in highly nonlinear fibers is detailed. These down conversion techniques are then implemented to phase-lock widely tunable mm-wave beatnotes well below the laser linewidth itself. Such achievements are made possible through a thorough trade-off between laser characteristics, optoelectronic arrangement, and electronic-feedback design. These advanced techniques give a new trend for bridging the gap between microwave and THz photonics.

Photonic technologies have a large potential to become the key enabler for millimetre-wave and THz application. Despite a number of advantages such as tune ability, high speed modulation and high coherence across the range, a number of issues still remain to be solved in terms of efficiency at emission and detection and power. We propose that photonics integration is key to help solving these problems. We will first present the key advantages of using photonic integration for this particular application, then discuss the different technologies that could be envisaged. Finally we will present recent integration results and discuss the achievements in regard of a few potential millimetre-wave and THz applications.

Stimulated Brillouin scattering (SBS) in optic fibers has potential applications for microwave photonic signal processing. The bandwidth tunability of SBS based microwave photonic filter (MWF) has been investigated theoretically and experimentally. Two tuning approaches, one is to alter the pump wave power and the other is to control the pump wave spectrum, are presented. The results show the latter one has more flexibility than the former one to tune the bandwidth of SBS based MWF.

We report on the first tunable opto-electronic oscillator based on a fiber ring resonator and a dual-frequency laser. The dual frequency optical signal is generated by a doubly tunable solid-state dual-frequency laser at telecom wavelength; both optical frequencies are electrically and independently tunable over more than 1 GHz bandwidth. The fiber-ring resonator is 25 meters long and its quality factor is close to 5.108. One laser line is stabilized on a resonance of the resonator with a PDH servo-controller. The heterodyne beatnote, still tunable by adjusting the frequency of the other line, is locked with a so-called optical frequency-locked loop based on the same resonator. As a result, the beatnote is stabilized on the closest multiple of the free spectral range of the resonator. At 10 GHz, we measured a phase noise below -85 dBc/Hz at 10 kHz.

A coherent detection RF-IF down converting link utilizing injection-locked distributed feedback (DFB) lasers is demonstrated. This photonic link design provides several RF performance advantages. Coherent detection allows unambiguous recovery of full time-domain I/Q IF signals. Injection locked laser design relaxes the tuning range requirement on RF local oscillators, and provides high optical power for efficient RF-IF conversion while minimizing degradation to link sensitivity due to phase noise. A cascaded injection locked configuration suppresses LO related spurious tones in the IF band is also demonstrated. Sensitivity and dynamic range data from RF C-band to Ka-band are presented.

We present and experimentally demonstrate a technique of simultaneous frequency and time information delivery on arbitrary intermediate point along a fiber loop link based on λ-dispersion-induced radio frequency (RF) phase locking. The equal and stable loop phase shift or time delay, clockwise and anticlockwise, is firstly achieved by altering the optical carrier's wavelength in the dispersive fiber link as well as a RF phase locking process in the central station. Due to the natural broadband operation, the frequency standard and time signal is carried always on the same wavelength. Given the locked loop phase shift, the stable frequency standard with twice the angular frequency of the RF reference can be recovered on intermediate point by simply mixing the RF signals in the two directions. Simultaneously, the delay difference between two directions from the central station to an arbitrary intermediate point is acquired, and the precise time information on the intermediate point is finally obtained through the above delay difference and the constant total loop delay. A 45-km fiber loop with two intermediate points is experimentally demonstrated. The Overlapping Allan Deviation of the recovered frequency reaches 2.04×10-13 after 1-s averaging and 1.71×10-16 after 104-s averaging. The Time Deviation (TDEV) of the delivered time information is measured to be 19.79 ps and 0.896 ps at 1 s and 103 s, respectively. The loop delay tunable range is in direct proportion to the fiber length, giving the capability of constructing a very long loop link.

We experimentally demonstrate, for the first time, bidirectional analog WiFi signal transmission in a digital wavelength division multiplexed passive optical network (WDM-PON) system. Our solution is compatible with a single optical feeder fiber and customer premises units employing reflective semiconductor optical amplifiers (RSOAs). The downlink optical carrier is modulated which both baseband 1 Gb/s On-Off-Keying (OOK) data and a WiFi signal in the 2.4 GHz band. The optical signal is split, with part going to reception and part reflected by the RSOA and modulated with an uplink WiFi signal. The uplink WiFi signal is in the 2.4 GHz band (no frequency translation), although the RSOA 3 dB response is limited to 1.2 GHz. At the bit-error-rate (BER) threshold of 2×10-3 before forward error correction (FEC), we achieve the transmission link up to 20 km (64-QAM), 30 km (16-QAM), and 40 km (QPSK). In all cases, the 1 Gb/s digital downlink signal is error-free.
我们首次通过实验证明了在数字波分多路无源光网络(WDM-PON)系统中双向模拟WiFi信号传输。我们的解决方案与单个光纤馈线光纤和采用反射半导体光放大器(rsoa)的客户端单元兼容。下行光载波由基带1gb /s的开-关键(OOK)数据和2.4 GHz频段的WiFi信号调制。光信号被分割，一部分去接收，一部分被RSOA反射，用上行WiFi信号调制。上行WiFi信号在2.4 GHz频段(没有频率转换)，尽管RSOA 3db响应被限制在1.2 GHz。在前向纠错(FEC)前的误码率(BER)阈值2×10-3下，我们实现了高达20 km (64-QAM)， 30 km (16-QAM)和40 km (QPSK)的传输链路。在所有情况下，1gb /s的数字下行信号是无差错的。

Transfer of Terahertz frequency reference via an optical fiber link was demonstrated. Utilizing a Brillouin scattering phenomenon of a long optical fiber link, only two optical modes of an optical frequency comb whose spectra broaden over 10THz are selectively amplified and transmitted. By photomixing the transmitted optical lights a THz frequency reference is generated at the end of the fiber link. We transmitted a 100GHz reference via a 50km spooled fiber, a 1km actually-laid fiber link and a 90km Tokyo urban fiber link, and evaluated their degradations due to the transmission.

A master-to-slave injection-locked weak-resonant-cavity FPLD directly modulated by 16 quadrature amplitude modulation (QAM) orthogonal frequency division multiplexing (OFDM) is demonstrated for DWDM-OFDM-PON transmission. By up-shifting the relaxation oscillation peak and suppressing the relative intensity noise of the WRC-FPLD under partially coherent injection-locking, the maser-to-slave WRC-FPLD pair shows comparable transmission performance with the coherently injection-locked WRC-FPLD by DFBLD, which is capable of serving as the universal transmitters in next-generation DWDM-PON.

We propose and experimentally demonstrate a broadband, frequency agile RF-photonic notch filter based on a waveguide Bragg grating on silicon, realized with CMOS compatible process via a multi-project wafer (MPW) run. The resulting RF filter shows a seamless tuning over 20 GHz of the central RF frequency of the notch, without changes in the shape of the filter response.
