WE4 9:15 AM - 9:30 AM<br />

Frequency Domain Training-Aided<br />

Channel Estimation and Equalization in<br />

Time-Varying Optical Transmission<br />

We propose a non-weighted feed-forward equalization<br />

method with filter update by averaging<br />

channel estimations based on short CAZAC<br />

sequences. Three averaging methods are<br />

presented and tested by simulations in a timevarying<br />

2×2 MIMO optical system.<br />

Single Mode Photonic Crystal Vertical<br />

Cavity Surface Emitting Lasers with<br />

Modulation Bandwidth > 13 GHz at Low<br />

Single mode photonic crystal vertical cavity<br />

surface emitting lasers with a modulation bandwidth<br />

exceeding 13 GHz are achieved at current<br />

density as low as 3.7 kA/cm 2 by separating the<br />

current and lasing apertures.<br />

WG3 9:30 AM - 9:45 AM<br />

Linear-Optics Realization of the Qubit<br />

Amplitude-Damping Channel using<br />

Phase Modulation, J. Capmany, Universidad<br />

Politécnica de Valencia, Valencia, Spain and<br />

C. R. Fernández-Pousa, Miguel Hernández<br />

Universidad of Miguel Hernandez, Elche,<br />

Alicante, Spain<br />

A conditional realization of the single-qubit<br />

amplitude damping channel is proposed. Kraus<br />

operators are probabilistically realized in dual-rail<br />

frequency basis by use of phase modulation and<br />

a fiber Bragg grating, resulting in success probabilities<br />

>31.5%.<br />

WH4 9:15 AM - 9:30 AM<br />

Design of Three-Dimensional Photonic<br />

Crystals for Large-Area Membrane<br />

Stacking, L. Lu, L. L. Cheong, H. I. Smith,<br />

S. G. Johnson, J. D. Joannopoulos and<br />

M. Soljacic, Massachusetts Institute of<br />

Technology, Cambridge, MA, USA<br />

We designed “Mesh-Stack” three-dimensional<br />

photonic crystals of 14% bandgap, that is fully<br />

compatible with the fabrication method to align<br />

and stack large-area single-crystal membranes<br />

containing engineered defects. A single-mode<br />

waveguide and disorder effects are presented.<br />

WE5 9:30 AM - 9:45 AM<br />

Real Time 1.55 µm VCSEL-based<br />

Coherent Detection Link, R. Rodes,<br />

This paper presents an experimental demonstration<br />

of VCSEL-based PON with simplified<br />

real-time coherent receiver at 2.5 Gbps. Receiver<br />

sensitivity of -37 dBm is achieved proving splitting<br />

ratio up to 2048 after 17 km fiber<br />

transmission.<br />

WF4 9:30 AM - 9:45 AM<br />

Coupled Semiconductor Ring Lasers,<br />

Brussels, Brussels, Belgium, G. Mezosi,<br />

M. Sorel, University of Glasgow, Glasgow,<br />

Scotland, UK, G. Verschaffelt and J. Danckaert,<br />

Vrije University Brussels, Brussels, Belgium<br />

We experimentally and theoretically study<br />

coupled semiconductor ring lasers. We report on<br />

the destabilization of unidirectional operation for<br />

large coupling strengths and the appearance of a<br />

coupling-induced bidirectional state, both undesirable<br />

for optical memory operation.<br />

Fabrication Technique of Highly Dense<br />

Aligned Semiconducting Single-Walled<br />

Carbon Nanotubes Devices, A. Elkadi,<br />

E. Decrossas and S. El-Ghazaly, University of<br />

Arkansas, Fayetteville, AR, USA<br />

A fabrication technique using dielectrophoresis<br />

is demonstrated to align semiconducting singlewalled<br />

carbon nanotubes (s-SWCNTs) and<br />

improve electronic devices performance. The<br />

proposed method produces highly dense<br />

aligned nanotubes (>40 s-SWCNTs/µm) and<br />

low sheet resistance (
