The impact of the frequency chirp measured for InP VCSELs with different kinds of design (high-bandwidth very short cavity and widely-tunable with micro electro-mechanical systems (MEMS) top mirror) is analyzed in case of discrete multitone (DMT) direct modulation in combination with 25-GHz wavelength selective switch (WSS) filtering. The maximum transmitted capacity for both dual side- and single side-band DMT modulation is evaluated as a function of the number of crossed nodes in a mesh metro network, comparing VCSEL based transmitters performance also with the case of external electro-absorption modulator use. Finally, the maximum reach achieved based on the received optical signal to noise ratio (OSNR) and the fiber span length is discussed.

Directly modulated long-wavelength vertical cavity surface emitting lasers (VCSELs) are considered for the implementation of sliceable bandwidth/bitrate variable transceivers for very high capacity transmission (higher than 50 Gb/s per wavelength) in metropolitan area systems characterized by reduced cost, power consumption, and footprint. The impact of the frequency chirp measured for InP VCSELs with different kinds of design (high-bandwidth very short cavity and widely-tunable with micro electro-mechanical systems (MEMS) top mirror) is analyzed in case of discrete multitone (DMT) direct modulation in combination with 25-GHz wavelength selective switch (WSS) filtering. The maximum transmitted capacity for both dual side- and single side-band DMT modulation is evaluated as a function of the number of crossed nodes in a mesh metro network, comparing VCSEL based transmitters performance also with the case of external electro-absorption modulator use. Finally, the maximum reach achieved based on the received optical signal to noise ratio (OSNR) and the fiber span length is discussed. The results confirm the possibility to use directly-modulated long-wavelength VCSELs for the realization of sliceable bandwidth/bitrate variable transmitters targeting 50-Gb/s capacity per polarization, also in the presence of 5 crossed WSSs for reaches of hundreds of kilometers in multi-span Erbium-doped fiber amplified (EDFA) metro links supported by coherent detection.

\n This paper proposes an original self-homodyne coherent system based on the copropagating pilot carrier, which does not require the SOP tracking at the receiver. The system allows to double the whole transported capacity with respect to the standard on-off keying (OOK) modulation thanks to a tailored modulation scheme combined with a specific transmitter (TX) based on the direct modulation of a single laser to achieve both the carrier and the signal, and a RX architecture based on direct detection. By means of suitable simulations, the performance of the proposed system is compared with respect to the employment of 4-level pulse-amplitude modulation (4PAM), which is a very effective modulation format able to double the capacity exploiting direct detection suitable for short-reach applications. Moreover, also polarization shift keying (POLSK) modulation is taken into account in the comparison. Finally, experimental measures confirm the feasibility of the proposed system.\n

\n Tellurium oxide is a promising optical material, conjugating transparency in the infrared with high refractive index, low chromatic dispersion with strong nonlinear response, elevated acousto-optic figure of merit and rare earth doping capability. Reactive sputtering is a suitable technique to obtain thin films of pure TeO2 glass, with tunable stoichiometry, without the need for added components to help vitrification. We report on the growth of tellurite thin films, on the linear and non-linear optical characterization and on the process technology to implement high-contrast planar optics. © 2008 IEEE.\n

\n The Resonant Router (ReR) is an integrated optical crossbar matrix based on the ring resonator. The ReR can operate as cross connect or wavelength router depending on the FSR and bandwidth of each node. In this contribution the cross connect characteristics are investigated, focusing on the characteristics of the single nodes, the necessaries technologies and the impact on WDM systems. An effective method for the BER estimation of the ReR is presented.\n

\n High electro-optic figure of merit n0\n3r41 and the absence of natural birefringence make semi-insulating gallium arsenide (GaAs) and cadmium telluride (CdTe) attractive materials for the fabrication of electro-optical devices. In this context we characterized both acoustic and optical phonon contributions to the electro-optic coefficient of CdTe and GaAs. Accurate measurements of n0\n3r41 as a function of modulation frequency and temperature were carried out on CdTe:In and GaAs crystal at 1.5μm. For CdTe, to the best of our knowledge, this is the first time that a contribution to the electro-optic coefficient due to optical phonons has been determined.

\n A new and effective method for the electromagnetic analysis of generic bent dielectric waveguides is presented. The method is based on the expansion of the bend mode in modes of the straight waveguide and permits determination of the shape and the phase constant of the fundamental mode of the bend waveguide with great accuracy at a very low computational cost. Simple analytical expressions of the phase constant, coupling losses, and bending-induced birefringence are derived under very general conditions. The proposed method is useful for the design and optimization of each bent section of integrated optics components.\n

The fulfillment of such requirements strongly depends on crystal growth technique and machinery process. We have developed a polarimetric two-dimensional mapping technique at ?? = 1.5 ??m, that comparatively characterizes the residual stress-induced birefringence of semiconductor modulator rods from a functional point of view, by evaluating the distribution of effective birefringence and estimating the overall noise figure of merit (cross-talk) for optical switching applications. We have examined high-resistivity CdTe rods grown by the horizontal Bridgman technique, and compared results to data from GaAs single crystals grown by horizontal Bridgman, liquid encapsulated Czochralski and vapor pressure controlled Czochralski.

\n Semiconductor-based bulk optical modulators and switches demand material homogeneity and lack of residual birefringence, to guarantee low attenuation and noise performances. The fulfillment of such requirements strongly depends on crystal growth technique and machinery process. We have developed a polarimetric two-dimensional mapping technique at ?? = 1.5 ??m, that comparatively characterizes the residual stress-induced birefringence of semiconductor modulator rods from a functional point of view, by evaluating the distribution of effective birefringence and estimating the overall noise figure of merit (cross-talk) for optical switching applications. We have examined high-resistivity CdTe rods grown by the horizontal Bridgman technique, and compared results to data from GaAs single crystals grown by horizontal Bridgman, liquid encapsulated Czochralski and vapor pressure controlled Czochralski.

\n A comparison is reported between the dynamical response of a single-mode fiber optic and resistive strain gages in the frequency range 25-250 Hz. The integral phase change of the laser light propagation into the vibrating fiber optic is evaluated. A mechanical system was designed to exactly delimitate the part of the optical fiber which is subjected to vibration. The frequency spectrum of the phase change signal and the resistive strain gage signal show equivalent behavior. This result is in good agreement with the theoretically expected values and confirms the validity of the analysis performed. © 1982 IEEE\n
