Several classes of indexprofiles can be used. Applications includenew transmission systems, sensors, andcomponents.

OWB1 • 8:00 a.m.Impact of Fiber Nonlinearities on Ad-vanced Modulation Formats Using Elec-tronic Pre-Distortion, Rene-JeanEssiambre, Peter J. Winzer; Lucent Tech-nologies, Inc., USA. We analyze nonlineartransmission of intensity-encoded andphase-encoded modulation formats usingelectronic pre-distortion. We show thatSPM similarly distorts all studied formats,and that XPM-induced burst errors re-main strong for phase-encoded signals.

OWD2 • 8:15 a.m.OSNR Enhancement Using a NovelPump-Wavelength Detuning Scheme forForward-Pumped Distributed RamanAmplification in a 40 Gb/s-Based WDMIn-Line Amplifier Transmission System,Takashi Kotanigawa1, Hiroji Masuda2,Toshiya Matsuda1, Shinji Matsuoka1; 1NTTNetwork Service Systems Labs, Japan, 2NTTNetwork Innovations Labs, Japan. OSNRenhancement by using a novel pump-wavelength detuning scheme for forward-pumped distributed Raman amplificationin a 40 Gb/s-based L-band WDM in-lineamplifier transmission system is experi-mentally verified for the first time.

OWB2 • 8:15 a.m.Chromatic Dispersion Tolerance of Co-herent Optical Communications Systemswith Electrical Equalization, BernhardSpinnler, Peter M. Krummrich, Ernst-DieterSchmidt; Siemens AG, Germany. Coherentdemodulation provides linear transfer ofdistortions from the optical into the elec-trical domain. We show by use of Monte-Carlo simulations which equalizer struc-tures available today are best suited toequalize chromatic dispersion after coher-ent demodulation.

Polymer Waveguides: The Future is Now,Garo Khanarian1, Robert Norwood2; 1Rohm& Haas, USA, 2Univ. Arizona, USA. Poly-mer waveguides have begun to be com-mercialized for applications such as pas-sive splitters, active switches and routingsignals on backplanes. We will present thekey attributes of polymer waveguides andnew emerging applications.

Garo Khanarian is Program Manager forOptical Packaging and DistinguishedScientist at Rohm and Haas. His currentresearch interests include encapsulants,photoresists, waveguides and packaging.He has a Ph.D. from the University ofSydney in Physical Chemistry and hasworked previously at Bell Labs, the Uni-versity of Massachusetts, Corning, andHoechst Celanese.

OWG1 • 8:00 a.m.Low-Biased Microwave-Photonic LinkUsing Optical Frequency or Phase Modu-lation and Fiber-Bragg-Grating Dis-criminator, Jinye Zhang, Thomas E.Darcie; Univ. of Victoria, Canada. A linearmicrowave-photonic link is presented inwhich a fiber Bragg grating converts phasemodulation into intensity modulation.DC-bias-related noise is reduced using agrating response that provides linear in-tensity modulation with low DC bias.

OWH1 • 8:00 a.m.Monolithic Vertical Integration of Metal-Oxide-Semiconductor Transistor withSubterranean Photonics in Silicon,Tejaswi K. Indukuri, Prakash V. Koonath,Bahram Jalali; Univ. of California at LosAngeles, USA. Monolithic integration ofphotonics and electronics has beenachieved in silicon by vertically integratingMetal-Oxide-Semiconductor Field-EffectTransistors and waveguide-coupledmicrodisk resonators in a double-layersilicon-on-insulator wafer, thus paving theway towards dense three-dimensionaloptoelectronic integration.

OWH2 • 8:15 a.m.An Optically Pumped Silicon EvanescentLaser Operating Continuous Wave at 60ºC, Hyundai Park1, Alexander W. Fang1,John E. Bowers1, Richard Jones2, Mario J.Paniccia2, Oded Cohen3; 1Univ. of Califor-nia at Santa Barbara, USA, 2Intel, USA,3Intel, Israel. We demonstrate a siliconevanescent laser operating CW up to60ºC. The laser operates at 1568nm with amaximum fiber-coupled output power of4.5mW. Devices are fabricated with siliconwaveguides bonded to AlGaInAs quantumwells.

OWG2 • 8:15 a.m.Radio over Fiber Distribution Systemwith OEO Repeater for 3G Cellular Sys-tems, Kaoru Imai, Yukio Horiuchi, NoboruEdagawa; KDDI R&D Labs, Japan. Wehave proposed a new radio-over-fiber(ROF) distribution system for 3G cellularsystems, which can concentrate ROF sig-nals from distributed cells on one opticalfiber deployed on existing optical accesssystems, and have successfully demon-strated sufficient reverse-link communica-tions.

pp) and very compact

InP-based n-i-n Mach-Zehnder modula-tor module. The module has a built-indriver IC. 43 Gbit/s single-drive push-pulloperation is demonstrated using this com-pact module.

OWD3 • 8:30 a.m.A New High-Power and Low-RIN RamanPump Laser for Improved Performancein Long-Span Unrepeated WDM Trans-mission Systems, Gabriele Bolognini1,Stefano Faralli1, Giovanni Sacchi2, ClaudiaCantini1, Fabrizio Di Pasquale1; 1ScuolaSuperiore Sant’Anna, Italy, 2Photonic Net-works Natl. Lab, CNIT, Italy. We propose ahigh-power and low-noise laser for effec-tive first- and higher-order co-pumping indistributed Raman amplifiers. Experi-ments at 10 Gb/s, also confirmed by simu-lations, point out RIN-penalty free trans-mission up to 25 dB of co-propagatingON-OFF Raman gain.

Labs, NECCorp., Japan, 2Jisso and Production Tech-nologies Res. Labs, NEC Corp., Japan, 3Sys-tem Platforms Res. Labs, NEC Corp., Japan.We have successfully demonstrated error-free transmission of 43-Gbit/s NRZ WDMsignals over a 405-km SMF having a maxi-mum of 15.6-ps DGD with our newly-developed equalizer. The equalizer re-moves fatal BER-degradations from rap-idly time-variant waveform distortions.

OWA3 • 8:45 a.m.New Details of Spun Fibers Measuredwith an OFDR, Tommy Geisler, PoulKristensen, Ole Knop; OFS Denmark, Den-mark.
