GRAND BALLROOM F GRAND BALLROOM G HARBOUR ROOM A GRAND BALLROOM A<br />

MU1 1:30 PM - 1:45 PM<br />

CD Equalization with Non-maximally<br />

Decimated DFT Filter Bank, I. Slim,<br />

L. G. Baltar, A. Mezghani, J. A. Nossek, Technical<br />

University of Munich, Munich, Germany and<br />

F. N. Hauske, Huawei Technologies Duesseldorf<br />

GmbH, Germany<br />

We perform CD compensation in the frequency<br />

domain through non-maximally decimated DFT filter<br />

bank with one-tap per sub-channel equalizer. Larger<br />

CD values are tolerated at the cost of slightly increased<br />

complexity compared to overlap-and-discard method.<br />

MV1 1:30 PM - 2:00 PM (Invited)<br />

Optical Interconnects for Computing<br />

Applications, B.-J. Offrein, IBM Research,<br />

Rueschlikon, Switzerland<br />

Optical interconnects are now emerging in<br />

computing applications. A tight integration of<br />

electrical and optical functions and novel<br />

assembly techniques are required to meet anticipated<br />

bandwidth, efficiency and cost<br />

requirements.<br />

MW1 1:30 PM - 2:00 PM (Invited)<br />

Enhancing the Efficiency of Photovoltaic<br />

Solar Cells with Photonic<br />

Nanostructures, G. Veronis, C. Min,<br />

C. H. Granier and J. P. Dowling, Louisiana State<br />

University, Baton Rouge, LA, USA<br />

We demonstrate that periodic metallic gratings<br />

can greatly enhance the optical absorption efficiency<br />

of thin-film solar cells. We also introduce<br />

aperiodic multilayer structures with highly directional<br />

absorptivity for both polarizations for solar<br />

thermophotovoltaic systems.<br />

MX1 1:30 PM - 2:00 PM (Invited)<br />

Light Management for Sunlight and<br />

Thermal Emission, Z. Yu and S. Fan,<br />

Stanford University, Stanford, CA, USA<br />

Light management is critically important for solar<br />

conversion devices. Similarly, in the reverse<br />

process when other forms of energy are<br />

converted into thermal radiation, light<br />

management can also be applied to enhance<br />

thermal emission.<br />

MU2 1:45 PM - 2:00 PM<br />

A New Cycle Slip Compensation<br />

Technique for Ultra High Speed Coherent<br />

Optical Communications, M. A. Castrillon,<br />

D. A. Morero and M. R. Hueda, Universidad<br />

Nacional de Cordoba, Córdoba, Argentina<br />

We propose a novel cycle slip mitigation algorithm<br />

suitable for next generation OTNs.<br />

Simulation results of a 100 Gb/s DP-QPSK<br />

optical system show almost no degradation at a<br />

post-FEC BER of 10 -6 .<br />

MU3 2:00 PM - 2:15 PM<br />

Real-time Comparison of Blind Phase<br />

Search with Different Angle Resolutions<br />

for 16-QAM, A. Al-Bermani, University of<br />

Paderborn, Paderborn, Germany<br />

The influence of phase noise related to 16 and<br />

32 test carrier phase angles of BPS carrier<br />

recovery in a 16-QAM transmission system has<br />

been investigated in real-time with a data rate of<br />

2.5 Gb/s.<br />

MV2 2:00 PM - 2:30 PM (Invited)<br />

Hybrid III-V on Silicon Lasers, B. Ben<br />

Bakir, A. Descos, D. Bordel, Ph. Grosse,<br />

N. Olivier, J-M. Fédéli, C. Kopp and<br />

S. Menezo, Commissariat à l’Énergie<br />

Atomique, Grenoble, France<br />

We report on hybrid III–V on Silicon lasers<br />

with adiabatic coupling. Fabry-Pérot laser<br />

with 16mW output power, integrated racetrack<br />

laser and photodetector, as well as<br />

widely tunable laser with 45nm tuning range<br />

are presented.<br />

MW2 2:00 PM - 2:15 PM<br />

Inverse Electromagnetic Design for<br />

Subwavelength Light Trapping in Solar<br />

Cells, V. Ganapati, O. Miller and<br />

E. Yablonovitch, University of California -<br />

Berkeley, Berkeley, CA, USA<br />

In the subwavelength regime, the optimal surface<br />

texture for light trapping in solar cells remains to<br />

be found. We use computational inverse electromagnetic<br />

design to find the optimal nanoscale<br />

surface texture.<br />

MX2 2:00 PM - 2:15 PM<br />

Resonant Dielectric-Grating Polarizers<br />

for Normal Incidence Operation, K. J. Lee,<br />

J. Giese, I. L. Ajayi, R. Magnusson, University of<br />

Texas at Arlington, Arlington, TX, USA, and<br />

E. Johnson, Clemson University, Clemson, SC,<br />

USA<br />

Design, fabrication, and characterization of<br />

guided-mode resonance polarizers with single<br />

dielectric layer are presented. These Si3N4 and<br />

TiO2 polarizers show high transmittance for TM<br />

and low transmittance for TE polarization at<br />

wavelength 1550 nm.<br />

MU4 2:15 PM - 2:30 PM<br />

On the Performance of Timing<br />

Synchronization Techniques for<br />

Optical OFDM IMDD Transmission,<br />

T. A. Truong, H. Lin, B. Jahan, L. Anet Neto,<br />

Orange Labs, Rennes, France, Cesson<br />

Sevigne, France, M. Arzel and M. Jezequel,<br />

Telecom Bretagne, Brest, France<br />

We do a comparative study of different timing<br />

synchronization techniques for optical OFDM<br />

IMDD transmission in single-mode fiber<br />

channel. Some modifications of Park’s method<br />

are proposed in order to obtain a more robust<br />

timing estimator.<br />

MW3 2:15 PM - 2:45 PM (Invited)<br />

Cheap, P. M. Fauchet, Vanderbilt University,<br />

Nashville, TN, USA<br />

This presentation reviews the potential usefulness<br />

of nanoplamsmonic enhancement of the<br />

response of Si solar cells and discusses results<br />

obtained with inexpensive Ag nanoparticles.<br />

Contrast Grating Reflectivity, T. Sun,<br />

W. Yang, Y. Rao and C. J. Chang-Hasnain,<br />

University of California - Berkeley, Berkeley, CA,<br />

USA<br />

Reflectivity of high contrast subwavelength<br />

grating (HCG) is experimentally characterized<br />

with the HCG being top reflector in an all-passfilter<br />

cavity. Large fabrication tolerance of HCG is<br />

demonstrated. Good agreement is achieved<br />

between experiment and simulation.<br />

and PolMux-Optical OFDM, K. Puntsri,<br />

University of Paderborn, Paderborn, Germany<br />

Coherent optical OFDM frame synchronization<br />

over 2,000 km of optical fiber at a sampling rate<br />

of 28 Gs/s is presented. A short training<br />

sequence is applied, which slightly affects to the<br />

OFDM frame efficiency.<br />

Substrates, H. Jeong, J. Sulkin, R.-H. Kim,<br />

J. A. Rogers and K. D. Choquette, University of<br />

Illinois at Urbana-Champaign, Urbana, IL, USA<br />

GaAs VCSELs are transferred onto hybrid<br />

substrates using Van der Waals bonding. Arrays<br />

transferred onto Si show that transfer technique<br />

does not degrade laser characteristics and<br />

transfer onto PET demonstrate flexible VCSEL<br />

arrays.<br />

Contrast SOI Waveguides for Integrated<br />

Holographic Filters, M. Verbist, D. J. Van<br />

Thourhout and W. Bogaerts, Ghent University,<br />

Gent, Belgium<br />

We design integrated holographic filters with any<br />

transfer function by weakly modulating the top<br />

cladding of SOI waveguides. Our calculations are<br />

confirmed by full-vectorial simulations. Grating<br />

are fabricated with focused ion beam.<br />
