Enabling the dynamic enablers: advanced optical performance monitors
- Trang TuJ4-TuJ4
We have shown that a tunable fiber grating-based optical monitor is an excellent
platform for advanced optical monitoring, and key to enabling the dynamic
enablers of next generation optical systems.

Hierarchical hybrid OTDM/WDM network
- Trang WF3-WF3
Hierarchical hybrid OTDM/WDM network is proposed for the future core-network. As
its enabling technologies, C- and L-wavelength-band generation, OTDM-WDM mutual
multiplexing format conversions, and ultrafast OTDM wavelength-band conversions
are reported.

Three dimensionally confined photon systems
- Trang TuL1-TuL1
The active region is given by a 5 nm In/sub 0.10/Ga/sub 0.90/As quantum well in
the center of the GaAs cavity. Microcavities with lateral sizes on the order a
few microns were fabricated by electron beam lithography and etching of the
layered structures, The use of cavities to enhance and suppress optical emission
rates by modifying the photon density of states has been a central interest of
resea...

Suppressing amplifier transients in lightwave systems
- Trang WE3-WE3
The implementation of the new features such as dynamic wavelength provisioning
and automated reconfiguration can lead to optical power transients in a
conventional gain-controlled EDFA, which is usually operated under saturation.
These signal transients can compromise the flexibility of network architecture
and impact overall system performance. Should a network be reconfigured or a
component fail...

Challenges for optical PMD compensation
- Trang TuN1-TuN1
This paper reviews the principle of optical polarisation mode dispersion (PMD)
compensation (OPMDC). It lays the emphasis on the challenges that OPMDC faces in
order to improve its implementation in a DWDM system.

Polarization mode dispersion and its mitigation in optical networks
- Trang TuN2-TuN2
PMD effects impose severe penalties on older fiber plants at 10Gb/s and on
virtually all plants at 40Gb/s. An optical compensator can mitigate these
penalties, allowing error-free performance without severely limiting the
regenerator distances. A repeatable, calibrated PMD emulator allows thorough
testing of a polarisation mode dispersion compensator (PMDC) and the calculation
of outage probabilit...

Polarization effects in ULH agile photonic networks
- Trang TuB1-TuB1
Error-free transmission under all polarization conditions in /spl ges/10 Gbit/s
ULH agile optical networks is achieved through dynamic control and through
margining for low-probability events. Simulation and experimental results are
presented that help to derive bounds on speed and magnitude of
polarization-induced impairments.

Tunable dispersion and dispersion slope compensators for 10 Gb/s using all-pass multicavity etalons
- Trang TuJ3-TuJ3
We propose and demonstrate a novel approach to multi-channel tunable dispersion
compensation based on multicavity etalons that can compensate all channels
throughout the C or L band with either 50 GHz or 100 GHz channel spacings for 10
Gb/s applications. We demonstrate very low group delay ripple, large tuning
range, as well as dispersion slope compensation for LEAF and TrueWave RS fiber
across th...

Vertical cavity surface emitting lasers laterally confined by 2-dimensional photonic crystals
- Trang TuP2-TuP2
Summary form only given. Recent increases in data traffic have motivated
research into vertical-cavity surface-emitting lasers (VCSELs) penetrating into
single mode regimes as well as multimode fiber links. For these applications, a
VCSEL with single mode operation has been demanded. We investigate a VCSEL
structure laterally confined by a 2D-photonic crystal using the effective index
model.
