An analytical model for mid-infrared (mid-IR) silicon Raman lasers (SRLs) is developed. The relative intensity noise (RIN) transfer from the pump to the Stokes in the lasers is also investigated. The analytical model can be used as a versatile and efficient tool for analysis, design and optimization of mid-IR SRLs. It is shown that conversion efficiency of 70% is attainable and the low-frequenc...

Quantum dash (Q-Dash) passively mode-locked lasers (PMLLs) exhibit significant low frequency relative intensity noise (RIN), due to the high mode partition noise (MPN), which prevents the implementation of multilevel amplitude modulation formats such as PAM4. The authors demonstrate low frequency RIN mitigation by employing 8B/10B and Manchester encoding with PAM4 modulation format. These encod...

Interferometric fiber-optic gyroscopes (IFOGs) are widely utilized due to their compact size and solid-state design. However, sensitivity of detecting rotation is limited by the relative intensity noise (RIN) associated with broadband source. To overcome this limitation, a conventional fiber ring resonator (FRR) can be employed filter RIN specifically at IFOG frequency. Nonetheless, implementin...

In this paper, we study the intensity noise performance of frequency-doubled lasers. particular, investigate how relative (RIN) multimode fiber lasers is affected by second harmonic generation process. We first develop an analytical approach and show that, in contrast with a single-mode laser, low frequency RIN (or excess noise) two-mode laser can increase more than 6 dB after frequency-doublin...

High-power semiconductor laser has more significant applications in long distance and high-reliability optical communication systems. It is noticed that the packaging plays an important role performance of high-power laser, including high output power, coupling efficiency, low relative intensity noise (RIN), so on. Usually, a symmetrical path, light, which incident directly parallel to axis len...

Relative intensity noise (RIN) induced penalties were experimentally measured in distributed Raman amplifiers (DRAs) for G.654.E and G.652.D fibres with forward, backward bidirectional pumping configurations. The signal RIN using the fibre was ∼3.5 dB ∼2 lower than forward (FW) pump configuration PM-QPSK PM-8QAM signals, single span transmission showing a Q-factor improvement of ∼3 ∼2.5 over fi...

Continuous-variable measurement-device-independent quantum key distribution (CV-MDI QKD) can defend all attacks on the measurement devices fundamentally. Consequently, higher requirements are put forward for source of CV-MDI QKD system. However, imperfections actual brings practical security risks to Therefore, characteristics realistic must be controlled in real time guarantee Here we propose ...

In optical frequency domain imaging (OFDI) or swept-source optical coherence tomography, balanced detection is required to suppress relative intensity noise (RIN). A regular implementation of balanced detection by combining reference and sample arm signal in a 50/50 coupler and detecting the differential output with a balanced receiver is however, not perfect. Since the splitting ratio of the 5...

A novel balanced electroabsorption modulated photonic link for simultaneous suppression of even-order distortions, third-order distortions, laser relative intensity noise (RIN), and common amplified spontaneous emission noise at the same modulator bias point was experimentally demonstrated for the first time. By biasing the balanced electroabsorption modulator at the thirdorder null, the third-...

A new pump-seeded, short-cavity Brillouin ring laser source layout intended for sensing applications is showcased, showing increased high maximum output (1.5 mW), a strong linewidth narrowing effect (producing light with of 10 kHz) and limited relative intensity noise (RIN ~ −145 dB/Hz), providing an ultranarrow, highly stable BRL that can also be employed as pump-probe optical time-domain anal...
