Multidimensional Optimum Signal<br />
Constellation Design for Few-Mode Fiber<br />
based High-Speed Optical Transport,<br />
T. Liu, University of Arizona, Tucson, AZ, USA<br />
We propose an algorithm to determine the N-<br />
dimensional optimum signal constellation<br />
design (ND-OSCD), in MMSE sense, for channel<br />
capacity achieving source distribution. The<br />
simulation results indicate that the proposed ND-<br />
OSCD outperforms QAM and sphere packing.<br />
Passive Polarization Mode Convertor<br />

Semiconductor Laser, M. A. Naeem,<br />

Glasgow, Scotland, UK<br />
A passive polarization mode convertor monolithically<br />
integrated within the cavity of a<br />
semiconductor laser is reported. A TE-to-TM<br />
conversion efficiency of more than 90% is<br />
obtained using back-to-back sub-wavelength air<br />
trenches.<br />
TuO2 11:00 AM - 11:30 AM (Invited)<br />
Interference Between Nanophotonic<br />
Resonances, S. Fan, Stanford University,<br />
Stanford, CA, USA<br />
We discuss some of the effects when strong<br />
interference occurs between nanophotonic resonances<br />
and the applications of such interference<br />
including dynamic control.<br />

Wide-Bandwidth Sub-100 µm Si Photonic<br />
Crystal MZI Optical Modulators at 10<br />
Gb/s, H. C. Nguyen, M. Shinkawa, N. Ishikura<br />
and T. Baba, Yokohama National University,<br />
Yokohama, Kanagawa, Japan<br />
We demonstrate the first sub-100 µm, 10 Gb/s<br />
Si MZI optical modulator. Slow-light photonic<br />
crystal waveguides enable carrier-depletion,<br />
near-error-free modulation in a 90 µm device by<br />
a 4.3 Vpp drive signal, with 17 nm bandwidth.<br />

BER Calculation of a Single Channel<br />
Nonlinear Fiber Optic Transmission<br />
System Based on QPSK, S. Naderi Shahi<br />
and S. Kumar, McMaster University, Hamilton,<br />
ON, Canada<br />
An analytical expression for the PSD of the<br />
nonlinear distortions is derived which significantly<br />
reduces the computational time of the BER<br />
estimation.<br />
TuN3 11:15 AM - 11:30 AM<br />
Monolithic Tunable Laser based on<br />
Selectively Intermixed GaAs/AlGaAs QW<br />
Structure, A. Zakariya and P. LiKamWa,<br />
University of Central Florida, Orlando, FL, USA<br />
We demonstrate a monolithic 10nm tunable<br />
integrated laser on a QW structure. Wavelength<br />
switching is achieved by steering an optical gain<br />
media laterally over two adjacent quantum well<br />
regions selectively intermixed to varying extents.<br />

Larger-Area Single-Mode Photonic<br />
Crystal Surface-Emitting Lasers Enabled<br />
by the Accidental Dirac-Point, S.-L. Chua,<br />
L. Lu and M. Soljacic, Massachusetts Institute of<br />
Technology, Cambridge, MA, USA<br />
We propose to obtain larger-area single-mode<br />
photonic crystal surface-emitting lasers by<br />
increasing the mode-spacing at the bandedge<br />
where the dispersions form an accidental Diracpoint<br />
at the center of the Brillouin zone.<br />

Crosstalk Using Coherent Optical<br />
Detection, M. A. Reimer, A. Borowiec, X. Tang,<br />
C. Laperle and M. S. O’Sullivan, Ciena<br />
Corporation, Ottawa, ON, Canada<br />
We present a direct measurement of the interchannel<br />
Kerr effect on the optical field of a<br />
continuous-wave probe affected by an on-offkeyed<br />
10 Gb/s pump. Measurements are used to<br />
verify predictions of the Manakov-PMD equation.<br />
Single-Mode Narrow-Linewidth and<br />
Tunable Two-Electrode Corrugated-Ridge<br />
Waveguide DFB Lasers, K. Dridi,<br />
A. Benhsaien, University of Ottawa, Ottawa, ON,<br />
Canada, J. Zhang, CMC Microsystem, Ottawa,<br />
ON, Canada and T. J. Hall, University of Ottawa,<br />
Ottawa, ON, Canada<br />
A single-mode and narrow linewidth two-electrode<br />
corrugated-ridge waveguide DFB laser has<br />
been fabricated. The preliminary characterization<br />
shows side-mode suppression ratios over 50 dB,<br />
a tuning range over 3.2 nm, and a linewidth of<br />
205 kHz.<br />
TuN5 11:45 AM - 12:00 PM<br />
Influence of Facet Phases on Adiabatic<br />
Chirp Behavior of Index-Coupled<br />
Distributed-Feedback Lasers, K. Kechaou,<br />
B. Thedrez, F. Grillot, Telecom ParisTech, Paris,<br />
France, G. Aubin, Laboratoire de Photonique et<br />
de Nanostructures, Marcoussis, France,<br />
C. Kazmierski, Alcatel Thales III-V Lab,<br />
Marcoussis, France and D. Erasme, Telecom<br />
ParisTech, Paris, France<br />
The adiabatic chirp for antireflection/high-reflection<br />
DFB laser is mostly dependent on<br />
high-reflection facet phase independently of the<br />
antireflection quality while very low reflectivity<br />
allows chirp predicting from the laser emission<br />
spectrum.<br />

Beating the Diffraction Limit with Perfect<br />
Confinement Inside a Right-Handed<br />
Cavity, V. Ginis, Vrije University Brussels,<br />

University Brussels, Brussels, Belgium,<br />
C. Soukoulis, Iowa State University, Ames, IA,<br />
USA and I. Veretennicoff, Vrije University<br />
Brussels, Brussels, Belgium<br />
We develop a novel approach to create optical<br />
resonators by applying the geometrical technique<br />
of transformation optics and we show that the<br />
fundamental diffraction limit can be overcome<br />
inside metamaterials with right-handed material<br />
parameters.<br />

Quality Factor for High Contrast Grating<br />
Resonators, L. Zhu, W. Yang and<br />
C. J. Chang-Hasnain, University of California -<br />
Berkeley, Berkeley, CA, USA<br />
The quality (Q) factor values of the high contrast<br />
subwavelength grating (HCG) resonator with<br />
different numbers of grating periods are studied.<br />
Q-factor >400 is achieved with only 2-period<br />
HCG having very small 0.58 λ 3 volume.<br />

Three-Dimensional Light Guiding in<br />
Photonic Crystals, K. Ishizaki, M. Koumura,<br />

University, Kyoto, Japan<br />
A new design of vertical waveguide is investigated<br />
for on-demand three-dimensional light<br />
guiding in three-dimensional photonic crystals.<br />
Optical characterization successfully demonstrates<br />
that the wide-band vertical guiding is<br />
realized in a fabricated photonic crystal.<br />

with other photonic components. It achieves a<br />
very high coupling efficiency of 59% with a 3dB<br />
bandwidth of 60 nm.<br />
