Enabling technologies for ultra-long haul transmission systems
LEOS Summer Topical Meeting - - Trang MC1-MC1
Xiang-Dong Cao
Ultra-long haul optical transmission systems are very complex, and require tremendous amount system level optimization. The process of integrating different technologies is strongly limited by system level trade-offs. Performance is not the only figure of merit, to some extend especially to ULH systems, the robustness and tolerance are more important. In this work, we will briefly summarize the ke...... hiện toàn bộ

Sapphire substrate-bonded ultra-low threshold 850 nm VCSEL array
LEOS Summer Topical Meeting - - Trang MH1-MH1
J. Jiang Liu, B. Riely, P. Shen, N. Das, P. Newman, W. Chang, G. Simonis
Oxide-confined vertical-cavity surface-emitting laser (VCSEL) 8/spl times/8 arrays were fabricated and off set flip-chip bonded onto sapphire substrates. These devices were further wire bonded in pin-grid-array (PGA) packages as optical transmitters. Optical output of the top-emitting 850 nm VCSEL array was transmitted through the transparent sapphire substrate. Lasing threshold as low as 24 /spl ...... hiện toàn bộ

Transparent optical networking-an European operator view
LEOS Summer Topical Meeting - - Trang MG1-MG1
A. Gladisch
From a system-theory point of view a transparent optical path in optical networks is defined by a path, which only passes 1-R regenerators, fibres or optical systems that can be characterised by a linear optical transfer function. Theoretically a transparent optical path allows the transmission of optical signals independently from data rate and modulation format. Client layer protocol transparenc...... hiện toàn bộ

Polarization mode dispersion and its mitigation in optical networks
LEOS Summer Topical Meeting - - Trang TuN2-TuN2
K.B. Rochford, G.R. Gray, D.L. Veasey
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...... hiện toàn bộ

Monolithically integrated wavelength converter: Sagnac interferometer integrated with parallel-amplifier structure (SIPAS) and its application
LEOS Summer Topical Meeting - - Trang WB2-WB2
Y. Suzuki, T. Ito, Y. Shibata
A Sagnac interferometer monolithically integrated with parallel-amplifier structure (SIPAS) is described. Filter-free wavelength conversion and full bit-rate conversion from 10-Gb/s random WDM channels to a 40-Gb/s channel were demonstrated.

Vertical cavity surface emitting lasers laterally confined by 2-dimensional photonic crystals
LEOS Summer Topical Meeting - - Trang TuP2-TuP2
N. Yokouchi, A. Danner, K.D. Choquette
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.

A system perspective of all-optical digital logic gates
LEOS Summer Topical Meeting - - Trang ME2
H. Avramopoulos
This presentation will review results from the recently completed European Commission funded project DO/spl I.bar/ALL (digital optical logic modules) on digital all-optical logic processing. The purpose of the project was to identify and demonstrate the necessary modules required to perform all-optical signal processing and to combine them to show non-trivial logical functionality.
