In this paper, we report on preliminary results of the study of two dimensional photonic band gap extended microcavity in a ridge waveguide with mode matching technique for good efficiency coupling between the input and output waveguides and the photonic crystal (PhC) structure. Transmission improvement above 70% at a wavelength of 1.55 /spl mu/m is reported with respect to the transmittivity achieved with conventional PhC structures without any matching feature.

The design of two dimensional guided wave photonic band gap filters based on Fabry-Perot microcavities is presented. Both single and multiple cavities structures have been simulated by applying the Bloch-Floquet modelling approach. Performances of the filters are suitable for DWDM telecommunication systems.

Optical networks can be analysed with the same methods as microwave networks if it is taken into account that optical signals can propagate in two different orthogonally polarised modes. The most appropriate way to accomplish this, is to use Jones vectors to represent the optical signal. In the theory of microwave networks, components are generally represented by complex scattering parameters which form the S-matrix of the device and represent the change of amplitude and phase of the signal propagating between the different ports. We adapted this formalism to fibre optic couplers used in optical networks, taking the polarization dependence of the devices into account. This enables the calculation of polarization effects in fibre optic communication networks and the exact simulation of fibre optic interferometric sensors.

Routing and steering of optical beams in guiding structures is an attracting function, especially for the realization of inter-chip and intra-chip optical dynamic interconnections. Several physical mechanisms were used, in a huge variety of materials and device configuration. In this paper we propose a simple solution that allows efficient beam steering in a PMMA/PUR/PMMA slab waveguide, by means of thermal control. The operation principle is based on the generation of a 2D temperature distribution field in the slab waveguide cross section, which induces lateral confinement for the propagating optical radiation. In particular, the choice for core and cladding fabrication, of materials characterized by negative thermo-optic coefficient, allows to push away the optical beam from the hottest region and control the spatial position by tuning the temperature difference between hot and cold electrode. In this way, it is possible to achieve a sort of "analog" operation of the device, whose steering efficiency is proportional to the dissipated power. It has been evaluated a maximum lateral beam steering of about 40 micron, before that the lateral confinement at the cold side vanishes Propagation analysis confirms the results obtained from the modal simulations. The high thermal efficiency of the structure allows the desired behavior with an estimated power expense of few of milliwatts, due to the extremely high thermal insulating characteristic of PMMA and PUR. On the other hand, its dynamic is quite slow; this fact is confirmed by simulated switching time of hundreds of milliseconds. An alternative proposal, with a PUR slab waveguide directly realized on an oxidized silicon substrate, shows faster switching times below one millisecond, but higher driving power.

Signal distortions in optical fibre systems arise from dispersive effects such as group velocity dispersion (GVD) and polarization mode dispersion (PMD). Dispersive optical filters offer the opportunity to completely compensate GVD. For PMD, adaptive polarization transformers in addition to 2/spl times/2 polarization-dependent filters are needed. Multi-stage 2/spl times/2 filters incorporating optical all pass filters are discussed that can compensate arbitrary polarization-dependent amplitude and phase responses across a desired bandwidth. To mitigate time-varying dispersion-induced impairments, adaptive filters are required, and control signals are needed to set the filter parameters to achieve the desired performance. Recent results are reviewed for planar waveguide device implementations with applications to tunable chromatic dispersion compensation, compensation of arbitrary phase responses, GVD and PMD monitoring, polarization transformers, and PMD compensation.

This paper is aimed at describing the realization of an electronic system for interrogation of fiber optic strain sensors for several application fields. One of the most important industrial sector where fiber sensors are becoming more popular is the aerospace industry, where the main applications are oriented to the strain monitoring inside metal or composite structures. These analyses are aimed mainly at obtaining higher safety level, higher structural reliability and lower maintenance and operative costs of aerospace structures. In particular, FBG sensors can be employed in the nondestructive control sector applications as structural test, structural health monitoring and loads monitoring. The work is centered on fiber optic Bragg grating (FBG) sensors, due to the possibility to detect strains in specific points of complex structures getting useful information for design and stress analysis. This application is of particular interest in the case of composite structures, fiber metal laminates and bonded structures. In fact, in these cases fiber optic sensors, thanks to their reduced dimensions, can be embedded in the part at critical points during the lamination or bonding process. In fact, fiber optic Bragg sensors, protected with a suitable coating like poly amide, can afford the autoclave cure cycle, without any damage, up to 9 bar, 180 /spl deg/C typically used for consolidation of composite parts. FBG sensors can be interrogated with different type of opto-electronic instrumentation and the resulting information, typically the electrical output signal produced by a photodetector, has to be acquired, sampled and elaborated by means of a dedicated electronic system. From a practical point of view, two different solutions could be adopted to implement the acquisition/processing of the data: a specialized hardware or a general purpose system. The first solution should lead to high effective, low cost systems, but the leak of flexibility, joined to high design cost and time, make the application-specific-system solution not a feasible one, except in the case of application with a large market. As counterpart, a solution based on a standard platform represents a valid answer to the flexibility needs. From this point of view the Pcbus extension for instrumentation (PXI) represents the best trade off between low cost PC platform and high performances devices as the VMEbus extensions for instrumentation (VXI) onces. Moreover, the advanced timing and synchronization available in the PXI devices allow precise time-based measurements to be performed. In the work the authors present an advanced interrogation system characterized by a high grade of portability and upgrading realized by using standard technology. The internal structure of the system and the user friendly graphical interface are also deeply described.

We conduct a detailed theoretical analysis of ultrashort pulse propagation through waveguide long-period grating (LPG) structures operating in the linear regime. We first consider the case of uniform LPGs and we also investigate the impact of the typical grating non-uniformities, e.g. grating profile apodization, and grating period chirping, in the spectral and temporal behaviour of LPG structures. Besides its intrinsic physical interest, our study reveals the strong potential of LPG-based devices for optical pulse re-shaping operations in the sub-picosecond regime.

We analyze the evolution of the cladding modes couplings in tilted fiber Bragg gratings when the fiber diameter and the refractive index of the surrounding medium are modified. To decrease the fiber diameter, we make use of hydrofluoric acid and to modify the external refractive index, we use a set of index oils. We also investigate a new way to correlate the spectral evolution of tilted Bragg gratings with respect to a change of the external refractive index.

We have proposed an optical pulse synthesizer, which consists of optical modulators and an arrayed waveguide grating (AWG). This system can generate arbitrary waveform pulses in combination with broadband optical frequency comb. We achieved generation of the Gaussian pulse with a width of 5.1 ps, double-Gaussian pulse and rectangular-shaped pulse as arbitrary waveform pulse synthesis, at a high repetition rate of 10 GHz.
