AI Article Synopsis
- This study mixes electro-optical (EO) comb lines with a Kerr frequency comb, showcasing their potential in coherent communications.
- By adjusting the modulation frequency, researchers can vary the number of EO lines integrated into the Kerr comb.
- The high coherence of both comb types, shown in a communication experiment with 10 Gbaud signals, suggests that this method can enhance data channels in optical communications.
Article Abstract
We experimentally insert a flexible number of electro-optical (EO) comb lines into a Kerr frequency comb via EO modulation and demonstrate the use of combined Kerr and EO combs as light sources in coherent communications. The number of EO lines inserted into the Kerr comb can be varied by changing the modulation frequency. Additionally, the inserted EO comb is found to have similar coherence to that of the Kerr comb, as indicated by their linewidths. The high coherence of both the Kerr and EO combs has further been demonstrated in a communication experiment in which the comb lines are encoded with 10 Gbaud quadrature phase-shift-keyed signals. The increased number of comb lines after EO modulation indicates the possibility of obtaining more data channels in optical communications.

Introduction: Ovarian Cancer (OC) was known for its high mortality rate among gynecological malignancies, often resulting in a poor prognosis. This study sought to identify prognostic necroptosis-related long non-coding RNAs (lncRNAs) (NRlncRNAs) with prognostic potential and to construct a reliable risk prediction model for OC patients.
Method: The transcriptome and clinic data were sourced from TCGA and GTEx databases.

The rising incidence of colorectal cancer (CRC) poses significant healthcare challenges. This study explored the therapeutic potential of combined curcumin (CUR) and metformin (MET) treatment in CRC models. Our findings indicate that the combination treatment (COMB) effectively downregulates the expression of divalent metal transporter-1 (DMT-1), leading to a reduction in cell proliferation aligned with suppression of the pAKT/mTOR/Cyclin D1 signaling pathway.

Turing patterns of alternating polarizations form between adjacent solitons, pushing them apart so that a random distribution of solitons along the cavity length spontaneously reaches equal equilibrium distances, the soliton crystal, without any mode crossing or external modulation. Enhancement of the frequency comb is achieved through the spontaneous formation of regularly spaced soliton crystals, 'self-crystallization', with greater power and spacing of the spectral lines for increasing soliton numbers.

Previous techniques have often been intricate, especially when dealing with a task of comb-mode hopping. In contrast, our method simplifies the mode-hoping method by tuning the piezoelectric transducer (PZT) at a rate of frep/2, while keeping the diode current locked to a fixed-frequency local oscillator (LO) at frep/4.

Several comb lines are carved into sampling pulses which are then time-dispersed along a single-mode optical fiber as a function of the electronically adjusted comb line spacing and the number of comb lines selected. Successful sampling and demodulation of QAM signals up to a 17 GHz carrier frequency with a sampling rate of up to 50 GSa/s have been demonstrated.
