Clock recovery circuit for optical packets
IEEE Photonics Technology Letters - Tập 14 Số 9 - Trang 1363-1365 - 2002

We demonstrate an all-optical clock recovery circuit for operation with short data packets of 10-Gb/s rate. The circuit uses a Fabry-Perot etalon and a nonlinear UNI gate and is capable of acquiring the clock signal within a few bits.

Long-haul DWDM/SCM transmission of 64- and 256-QAM using electroabsorption modulated laser transmitters
IEEE Photonics Technology Letters - Tập 14 Số 8 - Trang 1184-1186 - 2002
G.C. Wilson, J.-M. Delavaux, A. Srivastava, C. Hullin, C. McIntosh, C.G. Bethea, C. Wolf
We report the first eight-wavelength hybrid dense wavelength-division multiplexing/subcarrier multiplexing (DWDM/SCM) transmission over 800 km (ten spans) of standard single-mode fiber, with 1.04-Gb/s payload on each wavelength in 35 6-MHz 64-quadrature amplitude modulated (QAM) channels, without dispersion compensation. Forward error-correction coding (FEC) was used to achieve error-free performa...... hiện toàn bộ

Tunable sampled-grating DBR lasers using quantum-well intermixing
IEEE Photonics Technology Letters - Tập 14 Số 9 - Trang 1243-1245 - 2002
E.J. Skogen, J.S. Barton, S.P. DenBaars, L.A. Coldren
Widely tunable lasers are key components for wavelength division multiplexing fiber optic networks. They reduce cost in sparing, enable dynamic networking applications, and present opportunities for future monolithically integrated wavelength division multiplexing components. The sampled-grating distributed Bragg reflector (SGDBR) laser is ideal for these purposes. The authors present a centered q...... hiện toàn bộ

Vertically coupled InP microdisk switching devices with electroabsorptive active regions
IEEE Photonics Technology Letters - Tập 14 Số 8 - Trang 1115-1117 - 2002
K. Djordjev, Seung-June Choi, Sang-Jun Choi, P.D. Dapkus
InP vertically coupled microdisk resonator/waveguide switching devices with an electroabsorptive (EA) active region are demonstrated for the first time. The devices exhibit single-mode operation, large free spectral range of 10.5 nm and a high quality factor of 5700. The EA effect provides a way of loss-trimming the resonant characteristics. Active switches, routers, and fast modulators based on t...... hiện toàn bộ

All-optical logic NOR gate using two-cascaded semiconductor optical amplifiers
IEEE Photonics Technology Letters - - 2002
A. Hamie, A. Sharaiha, M. Guegan, B. Pucel
The authors present a novel all-optical logic NOR gate using two-cascaded semiconductor optical. amplifiers (SOAs) in a counterpropagating feedback configuration. This configuration accentuates the gain nonlinearity due to the mutual gain modulation of the two SOAs. The all-optical NOR gate feasibility has been demonstrated delivering an extinction ratio higher than 12 dB over a wide range of wave...... hiện toàn bộ

A unified Fourier transform theory for photonic crystal and FBG filters in the strong coupling regime
IEEE Photonics Technology Letters - Tập 14 Số 9 - Trang 1321-1323 - 2002
M.C. Parker, S.D. Walker
The authors present a new Fourier transform theory which provides analytic results for both strongly coupled fiber Bragg grating and photonic crystal filter structures. Trigonometric and hyperbolic descriptions of these important passive optical devices are well known for the regular grating case. However, the unified approach presented here, which is based upon a modified Debye-Waller approach to...... hiện toàn bộ

A study on the relationship between DWDM transmission performance and chromatic dispersion
IEEE Photonics Technology Letters - Tập 14 Số 9 - Trang 1276-1278 - 2002
K. Nakajima, M. Ohashi
In this letter, we numerically study the relationship between 40-Gb/s-based dense wavelength-division-multiplexing (DWDM) transmission performance and chromatic dispersion in two different transmission lines. We show that the optimum chromatic dispersion region for improving the DWDM transmission performance varies with the type of transmission line. We also show that a hybrid transmission line ha...... hiện toàn bộ
