Dataset for Cavity Effect on Phase Noise of Fabry-Perot Modulator-based Optical Frequency Comb
No full textWe study previously unconsidered filtering effect of a Fabry-Perot (FP) cavity on the phase noise of optical frequency comb generated with an FP-based electro-optic modulator. We found that phase noise can be suppressed by up to 30 dB for offset frequencies >FSR/finesse.

Multi-channel phase regenerator based on polarization-assisted phase-sensitive amplification
Full text linkWe propose and demonstrate simultaneous phase regeneration of six nonreturn-to-zero binary phase shift keying signals in a single nonlinear medium. The regenerating system,which exhibits binary steplike phase transfer functions, uses four-wave mixing in degenerate dual-pump vector parametric amplifiers implemented in the same nonlinear optical fiber, followed by polarization filtering. Bit-error-ratio measurements confirm optical-signal-to-ratio improvement and negligible crosstalk across all the regenerated channels, which were impaired at the regenerator input by broadband phase noise.</span
Stable latency (hollow core) optical fibres
No full textLight propagating through an optical fibre undergoes changes in group delay due to ambient temperature variations. This is detrimental in applications that are time-sensitive, including modern and next-generation telecom networks and infrastructures such as data centres. We review strategies to reduce this effect and in particular how emerging hollow core optical fibres can address this impairment.</p
Optical injection locking based amplification in phase coherent transfer of optical frequencies
No full textWe demonstrate use of an optical injection phase locked loop (OIPLL) as a regenerative amplifier for optical frequency transfer applications. The optical injection locking (OIL) provides high gain within a narrow bandwidth (< 100 MHz), and is capable of preserving the fractional frequency stability of the incoming carrier to better than 10^(-18) at 1000 s. The OIPLL was tested in the field as a mid-span amplifier for the transfer of an ultra-stable optical carrier, stabilized to an optical frequency standard, over a 292 km-long installed dark fiber link. The transferred frequency at the remote end reached a fractional frequency instability of less than 1 × 10^(-19) at averaging time of 3200 s.</span
