“…The phase noise of the generated signal was -70 dBc/Hz at an offset of 10 kHz, maintaining the spectral purity of the OFCG. The QDs mode locked laser having comb linewidth of few tens of kHz have the potential to be integrated with an optical phase lock loop [5] which can be part of a small foot print mmW source.…”

“…(2) and loop stability considerations, the maximum achievable bandwidth of an OPLL is ultimately limited by the loop propagation delay τ S . 10 OPLLs constructed using free-space optics 6 or integrated optics 11,12 offer the possibility of achieving bandwidths up to a few gigahertz. However, this is based on the assumption of a well-behaved SCL FM response F SC L F M ( f ).…”

Abstract. The bandwidth and residual phase noise of optical phaselocked loops (OPLLs) using semiconductor lasers are typically constrained by the nonuniform frequency modulation response of the laser, limiting their usefulness in a number of applications. It is shown in this work that additional feedback control using an optical phase modulator improves the coherence between the master and slave lasers in the OPLL by achieving bandwidths determined only by the propagation delay in the loop. A phase noise reduction by more than a factor of two is demonstrated in a proof-of-concept experiment using a commercial distributed feedback semiconductor laser.

“…Various optical modulation devices and sub-systems have been proposed to achieve stable millimeter-wave signal generation [4,8,9,10]. We may use two laser sources with fixed frequency separation for millimeter-wave signal generation [11,12], however, it is rather difficult to achieve stable operation due to phase and frequency fluctuation of the laser sources. On the other hand, optical modulation can provide very stable operation, where spectrum components are stably phase-locked in the optical output.…”

This paper describes photonic technologies for millimeter-wave generation and distribution. External modulation would be useful for stable and high-quality radio-over-fiber signal generation, where frequency stability and spurious suppression are very important for radio services such as mobile communications, radio locations etc. This paper provides outline of radio-over-fiber signal generation techniques. Precise and high-speed lightwave optical modulation would play important roles for suppression of undesired spectrum components. Photonic harmonic generation would be useful for very high-frequency signals. Reciprocating optical modulators consisting of optical modulators and fiber Bragg gratings can provide optical modulation by sub-THz signals.
