“…In this situation, time-domain method can be directly utilized to obtain the analytical expression for rms amplitude jitter of the extracted optical clock. From (6), the optical intensity of the extracted optical clock is given by (7) (8) (9) Note that (9) corresponds to Gaussian probability density function, which is only dependent on carrier linewidth and the value of [12]. We can easily observe that for various values of and , should have the same probability density function.…”

Abstract-A performance analysis of an optical clock extraction circuit based on a Fabry-Perot filter (FPF) is presented. Two analytical methods, time-domain and frequency-domain analysis, are developed in this paper. Time-domain analysis shows that there is no phase jitter in the extracted optical clock if the free spectral range (FSR) of the FPF is exactly equal to the signal clock frequency. Based on this, we obtain an analytical expression for root mean square (rms) amplitude jitter of the extracted optical clock in time domain, in which we have taken the impacts of carrier frequency drift and carrier phase noise into account. When the FSR of the FPF deviates from the signal clock frequency, both phase jitter and amplitude jitter will occur in the extracted optical clock. In this situation, a more general frequency-domain method is developed to deal with the timing performance under the assumption that carrier phase noise is negligible. This method allows us to calculate both rms phase jitter and rms amplitude jitter of the extracted optical clock. Using the developed two methods, we present a detailed numerical investigation on the impacts of finesse of the FPF, carrier frequency drift, resonator detuning, carrier phase noise, and optical pulse chirp on the timing performance. Finally, the application of this circuit in multiwavelength clock recovery is discussed.

divider and other SiGe ILFDs; the proposed ring-oscillator-based ILFD has wider-locking-range percentage. CONCLUSIONSA new small die area ring-oscillator-based ILFD circuit has been proposed and implemented in the 0.35 lm SiGe BiCMOS technology. The ILFD consists of four-stage of differential amplifier to construct an eight-phase oscillator, and the injection signal is applied to the tails of the differential amplifiers. The proposed ILFD provides an eight-phase output and wide-locking range from 12.7 to 15.25 GHz. The locking-range percentage of the proposed ILFD is the largest among the published SiGe HBT ILFDs.

The maximum frequency spacing of two channels is theoretically analyzed and experimentally demonstrated. The total wavelength span of the CR scheme is investigated to be about 3.37 nm in experiment. Multiwavelength CR can be implemented within the span.ABSTRACT: For the microwave photonic filters constructed with two cascaded Hi-Bi fibers, we demonstrate theoretically and experimentally a new technique that uses a dual-or tri-wavelength spacing-tunable laser source to greatly suppress the sensitivity of the filter response to environmental perturbations without the introduction of the phaseinduced intensity noise.

“…All-optical clock recovery, as one of fundamental technology for all optical reshaping and retiming, has been demonstrated using Fabry-Pérot lasers [1,2], phase-locked loops [3], multisection laser diodes [4], self-pulsating lasers [5], and stimulated Brillouin scattering (SBS) [6]. Most of the reported schemes are focused on the return-to-zero (RZ) format data.…”

the elimination of a conventional source inductor can improve overall LNA performance in subthreshold operation. CONCLUSIONA 5.8 GHz LNA using 130 nm CMOS technology has been presented, which operates in a subthreshold region for low power applications. The LNA consumes 980 W from 1.8V power supply and total chip area is 0.7 mm 2 . By eliminating a source degeneration inductor, forward gain of the LNA is improved. At the operation frequency, forward gain (S 21 ) is 13.4 dB and noise figure (NF) is 5.2 dB. This circuit has the highest FoM among the recently published subthreshold LNAs.
