TuE1 8:30 AM - 9:00 AM (Invited)<br />
Comparison of ISI-Mitigation Techniques<br />
for 128 Gb/s PDM QPSK Channels in<br />
Ultra-Dense Coherent Systems,<br />
J. Renaudier, P. Tran, H. Mardoyan, M. Salsi,<br />
F. Vacondio, G. Charlet and S. Bigo, Alcatel-<br />
Lucent, Nozay, Ile de France, France<br />
We investigate the possibility of packing<br />
100Gb/s PDM-QPSK channels with 28% overhead<br />
into a 33GHz-grid. We compare different<br />
inter-symbol mitigation techniques and show<br />
moderate penalties compared to a standard<br />
50GHz-grid.<br />

Beam Steering Modulation with Phased<br />
Vertical Cavity Laser Arrays, M. Johnson,<br />
University of Illinois at Urbana-Champaign,<br />
Urbana, IL, USA, D. F. Siriani, MIT Lincoln<br />
Laboratories, Lexington, MA, USA, and<br />
K. D. Choquette, University of Illinois at Urbana-<br />
Champaign, Urbana, IL, USA<br />
Beam steering with phased vertical cavity laser<br />
arrays is demonstrated at equipment-limited<br />
rates up to 100 MHz. The dominant phaseshifting<br />
mechanism is found to shift from<br />
thermal to carrier-induced effects with increasing<br />
modulation speed.<br />
TuG1 8:30 AM - 8:45 AM<br />
Determination of Waveguide Core and<br />
Cladding Refractive Indices using Single<br />
Wavelength Microring Reflectors,<br />
A. Arbabi and L. L. Goddard, University of Illinois<br />
at Urbana-Champaign, Urbana, IL, USA<br />
We present a method for accurate determination<br />
of refractive indices of waveguide core and<br />
cladding layers using reflective microrings. The<br />
resonant mode azimuthal order ambiguity is<br />
resolved by introducing a grating on the<br />
microrings.<br />
TuH1 8:30 AM - 9:00 AM (Invited)<br />
Multifunctional Fiber Sensors Based on<br />
Photonic Crystals, O. Solgaard, Stanford<br />
University, Stanford, CA, USA<br />
Optical interactions in 2D and 3D nanostructures<br />
enable multifunctional sensors. This talk<br />
describes the concepts, designs, fabrication, and<br />
system integration of sensors for a variety of<br />
measurands, including temperature, refractive<br />
index, force, and pressure.<br />
TuF2 8:45 AM - 9:00 AM<br />

Waveguide Laterally Integrated with<br />
VCSEL, T. Shimada, A. Matsutani and<br />
F. Koyama, Tokyo Institute of Technology,<br />
Yokohama, Kanagawa, Japan<br />
We demonstrate on-chip beam steering based on<br />
a slow-light Bragg reflector waveguide laterally<br />
integrated with VCSEL. Electro-thermal tuning of<br />
the slow-light waveguide enables continuous<br />
beam steering over 9° with a diffraction-limited<br />
divergence angle of 2.2°<br />
TuG2 8:45 AM - 9:00 AM<br />

Institute of Semiconductors, Chinese Academy of<br />
Sciences, Beijing, China<br />
We present a compact silicon microring modulator<br />
with record modulation speed. A novel<br />
zigzag PN junction is designed for high efficiency<br />
and high bandwidth. 44 Gbit/s NRZ modulation<br />
is demonstrated with 3 dB extinction ratio.<br />
TuE2 9:00 AM - 9:15 AM<br />

Telecom Orange Labs, Lannion, France,<br />
C. Gosset, Y. Jaouen and P. Ciblat, Telecom<br />
ParisTech, Paris, France<br />
We experimentally compare over 1000 km of<br />
G.652 fiber the performance of coherent DP-<br />
QPSK for 100 Gbps long-haul WDM<br />
transmission over DCF-free and legacy infrastructure<br />
supporting a 10 Gbps WDM system.<br />
TuF3 9:00 AM - 9:15 AM<br />

Emitting Lasers with Electrical Injection,<br />
A. V. Barve, Y. Zheng, L. A. Johansson and<br />
L. A. Coldren, University of California - Santa<br />
Barbara, Santa Barbara, CA, USA<br />
We report on the polarization dynamics in<br />
VCSELs with a small frequency modulation. The<br />
polarization state of a VCSEL is shown to be<br />
controlled by only changing the frequency of the<br />
modulation to electrical injection.<br />
TuG3 9:00 AM - 9:15 AM<br />
Electro-Mechanically Induced GHz Rate<br />
Optical Frequency Modulation in Silicon,<br />
S. Tallur and S. A. Bhave, Cornell University,<br />
Ithaca, NY, USA<br />
We present a monolithic silicon acousto-optic<br />
frequency modulator (AOFM) operating at<br />
1.09GHz. Employing mechanical levers to<br />
enhance displacement of the optical resonator<br />
enables an optical frequency modulation index of<br />
0.067.<br />
TuH2 9:00 AM - 9:15 AM<br />
Wideband Tunable Photonic Crystal<br />
Cavity with Electrostatic Actuation,<br />
M. Miri and M. Sodagar, Georgia Institute of<br />
Technology, Atlanta, GA, USA<br />
We present a wideband tunable optical cavity<br />
based on electrostatic actuation. Over 60nm shift<br />
in wavelength is achieved by applying less than<br />
1 Volt corresponds to a mechanical displacement<br />
of 30nm.<br />
TuE3 9:15 AM - 9:30 AM<br />

Keying Technology with Direct<br />
Modulation of Conventional DFB Laser<br />
and Digital Coherent Detection,<br />
N. Yasuhiko, NTT Corporation, Atsugi-city,<br />
Japan<br />
We propose an optical quaternary minimum<br />
shift keying technology with direct modulation<br />
for the first time. Error-free operation is obtained<br />
by using a digital coherent demodulator<br />
employing 1-bit delay detection and an adaptive<br />
FIR filter.<br />
TuF4 9:15 AM - 9:30 AM<br />

Yokohama, Kanagawa, Japan<br />
We demonstrate the athermal operation and the<br />
wavelength tuning of 850nm-GaAs-VCSELs<br />
using thermally actuated MEMS structure at the<br />
same time. A small temperature dependence of -<br />
0.011 nm/K and wavelength tuning of 4 nm was<br />
obtained.<br />

of 57% and quality factor of 4.5*10 6 composed<br />
of an on-chip microtoroid side coupled to two<br />
fiber tapers and investigate the thermal tunability<br />
and robustness of it.<br />

Electromagnetic Modes Localized at the<br />
Edges of a Three-Dimensional Photonic<br />
Crystal, L. Lu, J. D. Joannopoulos and<br />
M. Soljacic, Massachusetts Institute of<br />
Technology, Cambridge, MA, USA<br />
We find electromagnetic waves can be guided at<br />
the edge of a three-dimensional photonic crystal<br />
in air. A cell-counting approach describes its<br />
periodic evolution with interesting interplays<br />
among edge, surface and bulk states.<br />
