Nonlinear Compensation Algorithms with
Reduced Algorithmic Complexity, E. Ip,
NEC Laboratories America, Inc., Princeton, NJ,
USA
We review reduced-complexity nonlinear
compensation methods and find that filtered back
propagation and equivalent-span backpropagation
enable large complexity reduction for
dispersion managed and unmanaged systems.

Intra-Channel Nonlinear Compensation
for 112 Gb/s Dual Polarization 16QAM
Systems, Y. Gao, J. H. Ke, K. P. Zhong,
J. C. Cartledge and S. S.-H. H. Yam, Queen’s
University, Kingston, ON, Canada
The performance of the standard and low-pass
filter assisted digital back propagation algorithms
is investigated for a single 112 Gb/s dual polarization
16-ary quadrature amplitude modulation
(DP-16QAM) signal and a transmission distance
of 2400 km.

Digital Pre-Compensation of Inter-
Channel Crosstalk for Superchannel
System, J. Pan, C. Liu, T. F. Detwiler and
S. E. Ralph, Georgia Institute of Technology,
Atlanta, GA, USA
A digital inter-channel-crosstalk pre-compensator
for WDM “superchannel” systems is
proposed and demonstrated to outperform a
conventional ISI pre-compensator with 2dB
crosstalk suppression at the optimum optical
filter bandwidth and increase tolerance to net
filter bandwidth.

Ultrashort Pulse Generation in Diode
Laser Devices, I. H. White, P. Vasil’ev and
R. V. Penty, University of Cambridge, Cambridge,
UK
The generation of high-power femtosecond
pulses in visible and IR wavelength ranges by
superradiant emission in 3D, 2D and 0D semiconductor
laser structures is reviewed.
Advantages of this technique over mode locking
are discussed.

Direct RF Synchronization of a 22 GHz
Monolithic AlInGaAs Quantum Well Laser
with Sub-picosecond Pulse Generation,
E. Sarailou, A. Ardey and P. J. Delfyett, University
of Central Florida, Orlando, FL, USA
A 22 GHz AlInGaAs two-section mode-locked
laser is presented here. 860 fs optical pulses with
timing jitter of 280 fs (1 Hz-100 MHz) are generated
by direct RF modulation of the saturable
absorber.

Theoretical Demonstration of

Quantum Cascade Lasers with Quantum
Coherent Absorption, S. S. Shimu,
A. Docherty, M. A. Talukder and C. R. Menyuk,
University of Maryland Baltimore County,
Baltimore, MD, USA
We theoretically incorporate quantum coherent
absorption in an actively modelocked quantum
cascade laser. The laser self-starts from initial
quantum noise and produces a stable train of
modelocked pulses at high pump powers.

Platform, K. Nozaki, A. Shinya, S. Matsuo,
T. Sato, K. Takeda, C.-H. Chen, Y. Suzaki,
T. Segawa and M. Notomi, NTT Corporation,
Atsugi, Kanagawa, Japan
The on-chip integration of all-optical randomaccess
memories based on a photonic crystal
nanocavity was achieved. Their ultralow power
consumption, small footprint, and 40-Gb/s
optical signal capability might be beneficial for
future optical packet processing.

Quantum Light from CMOS-Compatible
Silicon Microresonators, S. Mookherjea,
University of California - San Diego, La Jolla,
CA, USA
Semiconductors with a high optical nonlinearity,
e.g., silicon, which can be lithographically
patterned into nanophotonic waveguides or
micro-resonators, may lead to on-chip roomtemperature
telecommunications-band quantum
light sources for complex and scalable systems.

Tunable Narrowband Filters Based on
SiN-on-SOI Platform, Q. Li, A. A. Eftekhar,
M. Sodagar, A. H. Atabaki and A. Adibi, Georgia
Institute of Technology, Atlanta, GA, USA
We propose a new scheme for tunable narrowband
filters using a silicon nitride on
silicon-on-insulator platform, which enables
reconfigurability, low propagation loss, and high
power handling capability. Preliminary results are
provided.

Room-Temperature Diamond,
I. A. Walmsley, University of Oxford, Oxford, UK
We demonstrate entanglement between the

Entangled photons are essential for scalable optical
quantum communication and processing. We
demonstrate electrical generation of entangled
light using a quantum dot within an LED, and
interactions between entangled photons by twophoton-interference.
