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 />

Linear-Optics Realization of the Qubit<br />
Amplitude-Damping Channel using<br />
Phase Modulation, J. Capmany, Universidad<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 />

Design of Three-Dimensional Photonic<br />
Crystals for Large-Area Membrane<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 />

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 />

Coupled Semiconductor Ring Lasers,<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 (
