TL;DR: Among the various fiber-optic sensor technologies, especially, technologies such as fiber grating sensors, fiber- Optic gyroscopes, and fiber-Optic current sensors are discussed with emphasis on the principles and current status.

TL;DR: In this paper, the quasi-stationarity is applied to the non-Kerr law nonlinearity of optical solitons and an approximate solution is obtained for some special cases of the nonlinearities.

TL;DR: In this paper, a wide range of different optical functionalities can now be obtained by modifications of the microstructure, as demonstrated by the fibres presented in this paper, such as singlemode, highly birefringent or show twin-core coupling.

TL;DR: In this paper, a two-pump fiber parametric amplifier with four parametric bands was proposed for flexible, unimpaired signal conversion, which can be used for flexible and unimperformed signal conversion over a broad spectral range.

TL;DR: In this article, the environmental sensing behavior of long period gratings written in three fibers with different refractive index profiles: step, W and a progressive three layered fiber was compared and significant differences in the behaviour of the three fiber types were found.

TL;DR: A review on optical transmission systems using POF and their enabling technologies and a summary of experimental data links with record capacity over record transmission distances is given.

TL;DR: In this article, the authors proposed a small dispersion fiber with large effective area and small slope, which has flat modal field over the central part of the core, which provides large mode field diameter (8.3 um at Λ0 = 1550 nm) leading to the relatively large area (Aeff = 56.1 um ) required to reduce nonlinear effects.

TL;DR: In this paper, the authors investigated gain dynamics in EDFAs pumped at 980 or 1480 nm when the input channel count is suddenly changed, and they found that when the pump power is simultaneously adjusted at the moment the input Channel count changes, the dynamic gain excursion of the surviving channels in the EDFA pumped at980-nm remains, although that in the EDFA pumped at 1480-nm is not observed.

TL;DR: In this paper, a uniform grating with a single phase shift in the center, a sinc-profile grating (with intrinsic phase shifts at the zeros), and a stretched cosine apodised grating were fabricated and characterised.

TL;DR: Polarization sensitive reflectometric measurements are effective tools for the characterization of polarization properties of optical-fiber link as discussed by the authors, which depends on whether they use a continuous wave source or a pulsed source to generate the probe signal.

TL;DR: In this paper, an analytical model was developed to evaluate the thermally induced apparent strain in fiber optic sensors embedded in cement-based composites, and the effects of thermal induced strain on embedded optical fiber were measured with a white-light fiber-optic Michelson sensing interferometer.

TL;DR: The main characteristics of a low-cost, ultra-compact, and intelligent erbium doped fiber amplifier (EDFA) are introduced and compared with those of the conventional wideband EDFAs and several reliability concerns that might be raised regarding to the cooler-less compact EDFA are answered.

TL;DR: The suitability of dispersion flattened fiber and dispersion shifted fiber as supercontinuum fiber is analyzed from the viewpoint of power variation and de-synchronization and a negligible power variation is observed across the 16 CW channels.

TL;DR: In this paper, a method to reduce the index chirp of fiber Bragg gratings and improve the spectral response is proposed and demonstrated using a doubled Argon UV laser (244 nm) and an interferometric Lloyd mirror assembly mounted on a translation stage.

TL;DR: In this article, the phase mismatch parameters in all possible FWM products in a dispersion-managed fiber (DMF) link become integer multiples of a common divisor and that, if this divisors coincides with an integer multiple of π radian, the Q-penalty caused by FWM can be quenched in theory.

TL;DR: In this paper, the performance of Tbps transmissions using wavelength-division multiplexing (WDM) technologies based on the 40 Gbps line rate is theoretically evaluated for various fiber types.

TL;DR: In this paper, an analytical model to account for amplified spontaneous emission (ASE) noise in long-haul systems is presented, which provides a drastic speed-up of system budgeting compared to conventional modeling based on split-step methods.
