In this paper we demonstrated blue laser generation at 473 nm in a BiB3O6 crystal at Type I phase matching performed with a diode-pumped Nd:YAG laser. For 1 W pump power output power of 20 mW at 473 nm has been obtained using a 5 mm long BiBO crystal.

An optical board technology consisting of SOI (silicon-on-insulator) based rib-waveguides and hybrid integration of active III/V components is presented. The use of SOI as the material base for an optical motherboard offers specific advantages, such as well know processing using standard equipment for board fabrication. Examples for the application of our board and waveguide technology are given. The board technology is introduced by presenting an optical transmitter for C-WDM transmission. It consists of four discrete lasers, which are multiplexed using an arrayed waveguide grating (AWG). The waveguide technology is presented by discussing an DPSK-receiver chip, combining advanced waveguide technology with a very well controlled birefringence of the component.

In this paper a novel combination of time domain and frequency domain analysis of optical waveguides using the method of lines and the discrete Fourier transform is presented. The hybrid algorithm is applied to propagation analysis in multimode optical waveguides. In extension of the existing method of lines analysis in the literature the algorithm allows the inclusion of time dependent effects, e.g. pulse broadening , incoherent optical sources with finite spectrum , time interference of modes and noise into the propagation analysis of optical waveguides. By using a combination of discrete Fourier transform and the method of lines an efficient algorithm is achieved which is ideally suited to the analysis of time periodic optical pulse propagation in long waveguide structures. Thus the analysis of time dependent pulse propagation in multimode waveguide structures with lengths up to kilometers and with more than thousand modes can be done on a standard personal computer.

In this paper we consider circular cavity consisting of a set of concentric rings with time varying dielectric permittivity. We explore how the transients evolve from the complex interaction of reflections occurring at the multiple dielectric interfaces. A closed form solution is obtained for the electric field component by applying the Laplace transform directly to the wave equation and enforcing the corresponding initial and boundary conditions.

In this paper, we examine for the first time to our knowledge, the potential of all optical regeneration for multiple input wavelengths at bit-rates beyond 40 Gb/s. The system parameters have been investigated assuming two and four channel operation. Successful regeneration has been achieved for two input channels at 40 Gb/s and 160 Gb/s. Four channel operation at 40 Gb/s has been investigated as well, illustrating Q-factor improvement and amplitude fluctuation suppression at the marks.

An extension of the method of single expression (MSE) for the analysis of plane electromagnetic wave oblique incidence on a dielectric slab is performed. Corresponding Helmholtz's equation, boundary conditions and the expression for power flow density are derived in the terms of MSE for TE and TM electromagnetic waves. TE wave oblique incidence on a wavelength-scale dielectric slab of low (high) permittivity surrounded by media of high (low) permittivity is analysed. The reflectance peculiarities of the slab and the distribution of electric field amplitude inside it are presented. For a slab of low permittivity surrounded by media of high permittivity the phenomenon of frustrated total internal reflection (FTIR) is observed and analysed.

We present an all-optical switch based on joint effects of dipole induced transparency (DIT) and electromagnetic induced transparency (EIT), that forbids the transparency induced by a dipole in an add-drop filter due to the vacuum Rabi shifting. The switching speed is very high, since only quantum interference between probe and pump signals is involved.

Static cross gain saturation and dynamical small signal cross gain modulation are experimentally and theoretically investigated in order to judge the multi wavelength amplification capability of quantum dot semiconductor optical amplifiers (QD SOA). The measurements reveal the carriers in the excited states of the QDs to act as an effective reservoir, where QDs of different sizes participate in the replenishment through the indirect coupling of the excited states of all the QDs via the wetting layer. The dynamical 3 dB cross gain modulation bandwidth is presently limited to below 3.5 GHz. Thus at high data rates the cross talk between the data channels is expected to be negligible and the multi-wavelength cross talk suppression should become better the higher the bit rate is. The unique reservoir mechanism of the QD system seems to be a major advantage of QD SOA compared to conventional bulk or quantum well amplifiers.

In this paper we present a novel adaptive routing strategy for OBS networks aimed at balancing global network load, in order to reduce overall burst loss probability. This strategy dynamically balances load in the output links of core nodes according to local congestion information. The results provided show a significant reduction in the load imbalancement of the links in the network, as well as a lower burst loss probability.

Network operators are continuously evaluating the Capital Expenditures (CapEx) and the Operational Expenditures (OpEx) to take important decisions such as the technologies that will be used, services that will be offered, prices of the services to be offered, etc. Our study focuses on the evaluation of the impact that protection has on the cost of a service during all its lifecycle. One could think that protected services may cost twice than the unprotected services but in this study we present some results on the cost comparison of different protection schemes on different optical platforms.
