efficiencies of 1.5, 2.0, and 3.8 pJ/b are achieved<br />
at 22.5, 25, and 28.5 Gb/s, respectively.<br />
MM3 11:15 AM - 11:30 AM<br />
All-Optical Modulation Format<br />
Conversion from 4-channels NRZ-OOK to<br />
RZ-16QAM using SOA-MZI Wavelength<br />
Converters, D. Hisano, A. Maruta and<br />
K.-I. Kitayama, Osaka University, Suita, Osaka,<br />
Japan<br />
We propose an all-optical modulation format<br />
converter in which 4-channels NRZ-OOK signals<br />
can be converted to RZ-16QAM. The converter<br />
consists of two SOA-MZI based OOK to 4ASK<br />
converters and a single SOA for offset compensation.<br />

Ultra-Compact Intra-Cavity Contacts for<br />
Multi-Terminal VCSEL Power<br />
Enhancement, C.-H. Lin, B. Thibeault,<br />
Y. Zheng, J. S. Parker, M. J. W. Rodwell and<br />
L. A. Coldren, University of California - Santa<br />
Barbara, Santa Barbara, CA, USA<br />
We demonstrate ultra-compact intra-cavity<br />
contacts fabricated with an embedded Al 2O 3 etchstop,<br />
which effectively shorten the cavity length<br />
and enhance the output power of a multi-terminal<br />
VCSEL.<br />
MO3 11:15 AM - 11:45 AM (Invited)<br />
Light Trapping and Solar Energy<br />
Harvesting with 3D Photonic Crystals,<br />
S. John, University of Toronto, Toronto, ON,<br />
Canada<br />
We describe designs of 3D photonic crystal<br />
silicon-based solar cells using architectures<br />
consisting of less than 1 micron of silicon,<br />
absorbing roughly 75% of all sunlight, with<br />
power efficiencies in the 15-20% range.<br />
MP3 11:15 AM - 11:30 AM<br />
P-Type D-Doping of Highly-Strained<br />
VCSELs for 25 Gbps Operation, A. V. Barve<br />
and Y. Zheng, University of California - Santa<br />
Barbara, Santa Barbara, CA, USA<br />
We present the utilization of d-doping to mitigate<br />
the rise in nonlinear gain compression in highlystrained<br />
InGaAs VCSELs and compare it with<br />
unstrained and undoped active region designs.<br />
High-speed 25 Gbps operation is also<br />
demonstrated.<br />
MM4 11:30 AM - 11:45 AM<br />
All-Optical 2R Regeneration of a 160-<br />
Gbit/s RZ- OOK Serial Data Signal Using<br />
a FOPA, J. Wang, H. Ji, H. Hu,<br />

Tianjin, China and L. K. Oxenløwe, Technical<br />
University of Denmark, Lyngby, Denmark<br />
All-optical 2R regeneration of a 160-Gbit/s RZ-<br />
OOK signal is demonstrated in a fiber optical<br />
parametric amplifier using a highly nonlinear<br />
fiber with the data as pump. Bit error rate bathtub<br />
curves validate the regeneration performance.<br />

Measurement of Optical Loss in Oxide-<br />
Confined VCSELs, S. T. M. Fryslie,<br />
D. F. Siriani and K. D. Choquette, University of<br />
Illinois at Urbana-Champaign, Urbana, IL, USA<br />
Cold-cavity spectral characteristics are used to<br />
extract the size dependent optical loss for small<br />
diameter oxide-confined VCSELs. For aperture<br />
diameters < 2 µm, the oxide scattering loss can<br />
be as large as 10 cm -1 .<br />

D. S. Wiersma, University of Florence, Sesto<br />
Fiorentino (Florence), Italy<br />
The addition of a tiny amount of Aluminum<br />
nanoparticles in dye solutions is shown to yield<br />
a significant enhancement of the down conversion<br />
of ultraviolet light while maintaining a high<br />
transparency at visible wavelengths.<br />

Novel Si-wire optical MUX/DeMUX employing<br />
microring resonator assisted delayed Mach-<br />
Zehnder interferometers is experimentally<br />
demonstrated. The fabricated device shows<br />
