We have designed and fabricated a 5-GHz fully integrated RTD/ HBT VCO using an InP-based technology for the first time. To achieve the wide-tuning range of the VCO, a p-n junction varactor was used in the L-C resonator, which has not been realized in previous works on RTD-based oscillators. As a res

Abstract
In this article, a new trueβtimeβdelay photonic system is presented that drives a phased array antenna for beam steering and beamforming. It is optimized to use the least possible number of components and utilizes a very simple operation. It is tolerable in small differences of the excitation phase and distance between the elements of the phased array antenna. Β© 2006 Wiley Periodicals, Inc.

## Abstract A flexible continuous optical beamformer with time delay for a phasedβarray antenna is proposed and demonstrated. It is constructed using a novel tunable chirped fiber grating achieved by bending a uniform grating, and a multiβwavelength fiber laser based on a novel Sagnac interferemetr
Ο-Electronic conjugation is not necessary to facilitate long-range energy migration and transfer: A rapid (k =1.04Γ10 s ) and efficient (Ξ¦ =71β%) energy transfer from the 28 photoexcited zinc porphyrin units to the focal free-base porphyrin unit occurs in a large, star-shaped dendritic multiporphyri
The proposed book will offer comprehensive and versatile methodologies and recommendations on how to determine dynamic characteristics of typical micro- and opto-electronic structural elements (printed circuit boards, solder joints, heavy devices, etc.) and how to design a viable and reliable struct
