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...

We introduce modeling and simulation of the noise properties associated with types modal oscillations induced by scaling asymmetric gain suppression (AGS) in multimode semiconductor lasers. The study is based on numerical integration a system rate equations 21-oscillating modes taking account self- cross-modal mechanisms. AGS varied terms pre-defined parameter, which controlled linewidth enhanc...

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...

OBJECTIVES Associations between cardiovascular mortality and air pollution and noise together were investigated. METHODS Data from the ongoing Netherlands Cohort Study on Diet and Cancer (120,852 subjects; follow-up 1987-1996) were used. Cox proportional hazard analyses were conducted for the association between cardiovascular mortality and exposure to black smoke, traffic intensity on the ne...

A high-power, low-noise photodetector, in conjunction with a current shunt actuator, is used in an ac-coupled servo to stabilize the intensity of a 10-W cw Nd:YAG laser. A relative intensity noise of 1 x 10(-8) Hz(-1/2) at 10 Hz is achieved.

We demonstrate narrow-linewidth-stimulated Brillouin lasers at 1064 nm from ultra-high-Q silica wedge disk resonators on silicon. Fundamental Schawlow-Townes frequency noise of the laser is on the order of 0.1 Hz2/Hz. The technical noise spectrum of the on-chip Brillouin laser is close to the thermodynamic noise limit of the resonator (thermorefractive noise) and is comparable to that of ultra-...

Abstract The performance of the optical frequency comb generation based on the re-circulating frequency shifter has been analyzed and demonstrated in this paper. We have theoretically analyzed the condition for flatness of the optical frequency comb and the relative intensity noise influence. We find out the influence to the flatness of optical comb owing to amplifier relative intensity noise a...
