When a short-length fiber Bragg grating is inscribed into a polarization-maintaining fiber, the resonant peaks produced by birefringence can overlap. In this case, the discrimination between strain and temperature effects is only possible by means of

In this paper, we analyze the polarization properties of uniform fiber Bragg gratings that are written into highly birefringent fibers. We study the evolution of the normalized Stokes parameters with wavelength for the reflected and transmitted signa

In this paper, we analyze the polarization properties of uniform Bragg gratings written into polarization maintaining fibers by studying the evolution with wavelength of the degree of polarization for both the reflected and transmitted signals. We pr

In this paper, we present a very reliable simulating algorithm to synthesize the physical parameters of a fiber Bragg grating structure from its reflection spectrum. The knowledge of the gratings parameters allows the determination of the maximum wav

We investigate numerically the dynamics of two semiconductor lasers mutually coupled via their optical fields in the particular case of a small separation between them. We show that, depending on the frequency detuning and the coupling between the la

We demonstrate anticipating synchronization between two chaotic laser diodes respectively subjected to incoherent optical feedback and incoherent optical injection. We investigate the robustness of the synchronization with respect to small parameter

The supermode noise of a harmonically mode-locked erbium-doped fiber laser with composite cavity is investigated both theoretically and experimentally. We propose a simple model based on the transfer function of the composite cavity. From this model,

An experimental study of supermode noise of harmonically actively mode-locked erbium-doped fibre lasers in the composite-cavity configuration is reported. Our study shows that the number of supermodes is reduced, as expected. However, this reduction

In optical CATV systems based on subcarrier-multiplexing technique, the joint action of semiconductor laser chirp and fiber chromatic dispersion gives rise to intermodulation distortion phenomena affecting the transmission performance. This problem h
