Among the new semiconductor materials for telecom devices, the GaInNAs-GaAs structure presents interesting properties for low-cost applications, like high differential gain and high T/sub 0/. Another key aspect of the performance is the behavior of the GaInNAs-GaAs based lasers under high bit rate direct modulation. Here, we demonstrate the dynamic ...

IMPACT OF PUMP OSNR ON NOISE FIGURE FOR FIBER-OPTICAL PARAMETRIC AMPLIFIERS

  • Bayart D.
  • Durecu-Legrand A.
  • Simmonneau C

Electrical measurements of the noise figure of a fiber-optical parametric amplifier are presented and compared with optical measurements. The transfer of pump noise by four-wave mixing was clearly demonstrated. A numerical model was developed to simulate the transfer of pump noise and validated by these measurements. Using this model, we ...

DISCUSSION ON RIN IMPROVEMENT USING A STANDARD COUPLER

  • Dross F.
  • Marceaux A.
  • Thibon C
  • Vodjdani N.

It is possible to increase the signal-to-noise ratio (SNR) of radio-frequency optical links by a factor of N by combining the light of N individual lasers. The individual relative intensity noises (RINs) are then averaged, and the equivalent noise is lowered. However in some cases, while using a standard 3-dB ...

SERVICE CONVERGENCE USING MPLS MULTISERVICE NETWORKS

  • Aissaoui M.
  • Bocci M.
  • Watkinson D

Enterprises are increasingly using virtual private networks to interconnect remote sites. Traditionally, service providers have used ATM core networks to deliver layer 2 services such as frame relay, ATM, or TDM private lines, which enterprise customers have then used to build their corporate network infrastructure. Such services account for the ...

SIP-BASED VERTICAL HANDOFF BETWEEN WWANS AND WLANS

  • Wu W.

Future-generation wireless networks have been envisioned as the integration of various wireless access networks, including both wireless wide area networks and wireless local area networks. In such a heterogeneous network environment, seamless mobility support is the basis of providing uninterrupted wireless services to mobile users roaming between various wireless access ...

ROBUST SOURCE DECODING OF VARIABLE-LENGTH ENCODED VIDEO DATA TAKING INTO ACCOUNT SOURCE CONSTRAINTS

  • Nguyen H.

We first provide an analysis of available redundancy remaining in compressed video data. This residual redundancy has two origins: the variable-length code (VLC) syntax and the source constraints. We compute the two in terms of equivalent redundancy bits. Then, a VLC decoding algorithm able to exploit both VLC syntax and ...

MULTILAYER TRAFFIC ENGINEERING FOR GMPLS-ENABLED NETWORKS

  • Berde B.
  • Vigoureux M.

In recent years, significant work has been completed on traffic engineering enhancements to the generalized multiprotocol label switching protocol suite (E. Mannie Oct 2004) (D. Katz et al., Sept. 2003) (K. Kompella et al., Oct 2003). As a next step, reproducing the current trend of switching layers' integration happening in ...

FABRICATION OF THICK SIO2 BLOCK WITH DRY-RELEASED UNDERNEATH CAVITY IN SILICON FOR RF MEMS

  • Puech M.

A so-called SiDeox new technology to fabricate a thick silicon oxide layer with an underneath cavity for applications in RF MEMS devices is presented. Photolithography was performed on the silicon substrate with 1.8 /spl mu/m patterns. Deep reactive ion etching (DRIE) using Alcatel A601E ICP etcher was performed to form ...

SINGLE CHIP 58 GHZ RADIO RELAY FRONT END

  • Gouessant P
  • Marchand P.

This paper describes a solution for a low cost front end to be used in point to point radio relays operating in the uncoordinated 57.5 to 59 GHz frequency band. The main characteristics of the equipment operating in this band in Europe have recently been agreed in draft by the ...
