2006
International Microwave Symposium


Welcome to the IMS2006 Print-on-Demand ordering page.
Papers ordered from this page will be printed and delivered to the conference site to be picked up by attendees at the IEEE Membership booth. The papers will be individually printed and packaged with the attendees name and company for easy identification.

Papers can be ordered during pre-registration. These papers will be available to the attendees on the morning of the first day of the conference. Papers can also be ordered during the conference and will be printed and delivered the next morning for pickup.

We hope this service will enhance your symposium experience.

TU1A-01
A detailed investigation of UTC traveling wave photodetectors
D. Pasalic, R. Vahldieck, Swiss Federal Institute of Technology, Zurich, Switzerland
Effects of the absorber thickness on the UTC TWPD's performance are investigated. This is an important parameter because it affects both external efficiency and the bandwidth of the device. The analysis of the photodetectors is done using a hybrid DD-TLM method. A thicker absorber improves the external efficiency of the UTC TWPD, but also reduces its transit bandwidth. It is found that the bandwidth of the UTC TWPD can be optimized by properly chosing the length of the device.
TU1A-02
An LTCC-based Wireless Transceiver with Integrated Optical Interface
L. Pergola*, R. Gindera**, D. Jaeger**, R. Vahldieck*, *Swiss Federal Institute of Technology Zurich, Zurich, Switzerland, **Universitaet Duisburg-Essen, Duisburg, Germany
This paper describes the realization of an LTCC based optical wireless-transceiver using radio-over-fiber (RoF) techniques. For the first time, single mode optical fibers are employed, making this device particularly attractive for indoor and outdoor distributed antenna systems. The operating frequencies are in the 5-6 GHz band.

Miniaturized Optical Delay Lines Using Photonic Crystals
M. Fakharzadeh Jahromi, O. Ramahi, S. Chaudhuri, A. Safavi-Naeini, University of Waterloo, Waterloo, Canada
we introduce a novel structure which produces the longest delay, lowest transmission loss and least crosstalk noise in comparison with classical delay lines. The delay generated by this b structure is almost uniform over a wide range of wavelengths. We demonstrate that by introducing coupled defects in the Reflective Spiral structure, the delay increases by a factor of five, corresponds to propagation of lightwave 63 times slower than free space

A Novel Class E Analog Fiber Optic Link with RF Power Gain and High DC-RF Conversion Efficiency
W. D. Jemison*, A. Paolella**, *Lafayette College, Easton, USA, **Artisan Laboratories, Inc., New Britain, USA
A novel analog fiber optic link is described that incorporates class E switching amplifier techniques in the link architecture to provide RF power gain with high post-detector dc-RF conversion efficiency. The proof-of-concept link was designed to operate at a nominal design frequency of 70 MHz and has an RF gain of 30 dB and a post-detector power amplifier dc-RF conversion efficiency of 78%.
TU1A-05
Adaptive Electronic Linearization of a Coherent Heterodyne Optical Receiver
J. Basak, B. Jalali, University of California, Los Angeles, Los Angeles, USA
We demonstrate the electronic linearization of a coherent heterodyne receiver in a phase modulated optical link. Third order nonlinearity suppression of 7.2 dB and spurious free dynamic range (SFDR3) improvement of 2.4 dB is obtained with an adaptive CMOS linearizer circuit.
TU1A-06
Gigabit Transmission in 60-GHz-Band Using Optical Frequency Up-Conversion by Semiconductor Optical Amplifier and Photodiode Configuration
J. Seo, W. Choi, Yonsei University, Seoul, Korea
We demonstrate error-free 1.244-Gbit/s ASK data transmission based on remote frequency up-conversion technique in 60-GHz-band radio-on-fiber systems. For frequency up-conversion, 63-GHz optical heterodyne LO signals are cross-gain modulated by another optical baseband signal in SOA, and up-converted signals are generated after photodetection. The dependence of BER characteristics on the power and wavelength of optical baseband signals and the power of optical LO signals is also investigated.
TU1A-07
Full-duplex DOCSIS/wirelessDOCSIS Small-Scale Field Trial Employing Hybrid Fibre Radio Systems
H. Pfrommer, M. Piqueras, V. Polo, J. Marti, Universidad Politecnica de Valencia, Valencia, Spain
The simultaneous wireline and wireless full-duplex operation of DOCSIS signals in an small-scale field trial is reported. The deployed network consists of a 4.2 km fiber link, a 370 m radio link and an indoor cable distribution network. At the CS, the DOCSIS wireless replica is generated by means of an optical harmonic mixing technique based on a DD-MZM. The optical signal is fed to a BS where a packaged AFPM acts simultaneously as a photodetector and modulator.
