Several optical beamformer architectures are analyzed in terms of their performance for base station in broadband wireless access networks in millimeter-wave frequency bands. Both upstream and downstream configuration are described and their ability to offer multibeam capability has been considered. The measurements obtained confirm their performance. The work presented here has been carried out in the frame of the IST 2000-25390 OBANET project.

We have experimentally investigated the dynamic performance and the suppression of nonlinear distortions of a monolithic optical injection-locked distributed feedback (DFB) laser. The master and the slave lasers are monolithically integrated in a single strip of strongly coupled DFB laser. Optical injection locking is achieved by current tuning. The resonant frequency of the laser is increased from 11 GHz to 23 GHz, and nonlinear distortions are suppressed by more than 15 dB.

Simulations and measurements are carried out to evaluate dispersion resistance of up-conversion systems using one-electrode/push-pull Mach-Zehnder modulators or a passive unbalanced interferometer. This former solution causes very low fluctuations for mixing power as a function of fiber length.

The HUT Radio Laboratory develops a novel compact radar cross section (RCS) test range for scale model measurements. The test range is based on a phase hologram that converts the feed horn radiation to a plane wave. The measurements are performed using CW at 310 GHz in a quasi-monostatic radar configuration where the identical receiving and transmitting corrugated horn antennas are placed side by side. The feasibility of the phase hologram RCS range has been verified with simple test objects such as a metal sphere and a small metal plate. The work continues toward a monostatic radar configuration.

Optical components for commercial and defense systems are becoming readily available due to demand in new military applications in surveillance and countermeasures and commercial applications in communications. In defense systems such as phased array antennas and fiber optic decoys, high performance is required of the optical components both in narrow band for RF and wideband in countermeasure. In commercial applications, the expected high demand of two-way fixed and mobile wireless services, the consequent need of expanding the systems capacity, and the urgency of reducing the costs, has created an opportunity for the utilization of hybrid fiber wireless transport in wireless networks. These systems offer the potential to improve services and reduce base station costs through increased bandwidth and easy of installation. System demonstrations for personal communications services operating at 1.9 GHz up through Ka Band (26 to 40 GHz) have been developed. In many of these applications the key is to integrate the optical components with the microwave circuits to reduce size, cost and improve performance particularly at millimeter wave frequencies.
