Presents an efficient method for the design of complex fiber Bragg gratings. The method relies on the synthesis of the impulse response of the grating by means of a differential layer-peeling algorithm. The algorithm developed takes into account all

This paper studies the acousto-optic interaction induced by an acoustic flexural wave among the optical propagation modes supported by tapered optical fibres. We have investigated the evolution of the acousto-optic resonance condition as the fibre is

The simultaneous determination of strain and temperature distributions from the measurement of noise-initiated Brillouin scattering (NIBS) power and frequency shift in optical fibers is discussed. Equations governing the growth of the NIBS signal are

We present a theoretical analysis of the mode coupling induced by the optical Kerr effect in a high birefringence fiber. Several pump-probe architectures which allow mapping of the birefringence along the fiber are studied. The application of nonline

One of the advantages of the use of optical fibers for sensing is their ability to perform distributed measurements. Several distributed sensors that measure temperature along optical fibers are already commercially available. All of them are based o

A new tunable dispersion compensator that does not suffer from higher order dispersion is reported. The device consists of two quadratically chirped fiber Bragg gratings, each with linear strain actuators. The module has a tuning range of 500 ps/nm a

High-spatial-resolution measurements of axial-stress profiles of UV-irradiated fibers are reported, providing diagnostic information and a technique for the direct observation of UV-written grating structures. Measurements have been made with a spati

The existence of dead-zones is an important drawback for optical time-domain reflectometers (OTDR), specially in short haul applications with a large number of optical components. In this letter, we present an OTDR system with high spatial resolution

We have demonstrated an add-drop multiplexer based on a novel half-cycle non-uniform fused compact coupler. Symmetric operation was experimentally verified. Non-destructive coupler characterization shows the extended slightly coupled region where the
