“…A number of such spectral tones can be produced by the generation of higher harmonics due to phase or intensity modulation [22][23][24][25][26] or a pumped fiber loop [27]. Conventional optical filters are then used to select two particular lines.…”

The interference between two spectral lines of the frequency comb of a fiber femtosecond laser is used to generate millimeter-wave and terahertz tones. The two lines are selected by stimulated Brillouin scattering (SBS) amplification. All other modes are strongly rejected based on polarization discrimination, using the polarization-pulling effect that is associated with SBS. The inherent high spectral quality of a femtosecond fiber laser comb allows generation of millimeter-and terahertz waves with linewidths below 1 Hz, and a phase noise of -105 dBc/Hz at 10 kHz offset. The generation, free-space transmission and detection of continuous waves at 1 THz are demonstrated as well. Lastly, the generated millimeterwave carriers are modulated by 40 Gbit/s data. The entire system consists of a fiber laser and standard equipment of optical telecommunications. Besides metrology, spectroscopy and astronomy, the method can be utilized for the emergent field of wireless millimeter-wave and THz-communications at ultra-high data rates.

“…In realizing RF carrier generation and data upconversion, SBS can be a promising candidate since it can provide narrow bandwidth, high power gain [4] and has low phase noise properties [10]. However, the narrow gain bandwidth of several tens of megahertz also limits its data bandwidth [3,11].…”

“…Another carrier generation technique is optical frequency multiplication (OFM), achievable through various combinations of external modulators or nonlinear processes such as SBS and four‐wave mixing (FWM). Some researchers have reported positive results with SBS‐based photonic frequency tripling or quadrupling [7–10], FWM‐induced tripling or sextupling multiplication [11–13], and FWM and SBS co‐induced frequency multiplication [14]. Most OFM is based on the generation of desired multiple order MMW carriers to amplify desired and suppress undesired optical harmonics via modulation conditions and optical nonlinearities.…”

As shown in the inset in Figure 12, the maximum ratio fluctuation at a constant temperature is $0.002 dB. As the slope of the ratio of the system is 0.00238 dB/ C, the estimated temperature resolution is 0.84 C. 4. CONCLUSIONS 2. C. Seo and T.

By placing two single mode fibers and a semiconductor optical amplifier (SOA) along the bidirectional loop, we were able to implement the process. In particular, by combining SBS and FWM effects during bidirectional transmission, we effectively obtained a MMW carrier through multiple sidebands amplified by two optical nonlinearities. During experimentation, the generated MMW carrier displayed a narrow linewidth of 314 Hz at a frequency of 54.26 GHz, as well as phase noise of À81.50 dBc/Hz at 10 kHz offset.ABSTRACT: This article presents a differential cross-coupled complementary Colpitts CMOS voltage-controlled oscillator (VCO). The low phase noise CMOS VCO has been implemented with the TSMC 0.35-lm 2P4M CMOS technology and adopts a pair of cross-coupled PMOS transistors to achieve faster start-up oscillation. The VCO operates from 6.16 to 6.5 GHz with 5.3% tuning range. The measured phase noise at 1 MHz offset is À121.12 dBc/Hz at 6.417 GHz.
