We present a basic configuration of an unique integrated-optic arrayed-waveguide grating
(AWG) multiplexer with loop-back optical paths and demonstrate an add-drop multiplexer …

We analyze the transmission of many wavelength-division-multiplexed (WDM) channels
through a cascade of erbium-doped fiber amplifiers (EDFA) in both long-distance links and …

This device includes optical add-drop multiplexers (M1 to M2) each having a band-pass
filter. An optical switch (C1) has outputs connected to the multiplexers. An optical coupling …

We propose a reconfigurable optical add/drop multiplexer-demultiplexer based on arrayed
waveguide grating with fold-back technique in AWG. The design with 8 channels …

Optical component adapted to monitor a multiwavelength link for use as an add-drop
multiplexer in optical networks. The optical component includes an input fiber (68) for …

A method and system for the transmission of signals over a large capacity local access
network which provides users a dedicated two-way link to a central office The network is …

According to the invention, a first band-pass multidielectric filter (F1) receives optical signals,
transmits at least one of them and reflects the untransmitted signals. An adding means (F2) …

A simple method for optimization of individual amplifier performance parameters for multiple
wavelength operation is presented. The method determines the erbium fiber length required …

The first part of this paper reviews the spectrally resolved erbium-doped fiber model by
Saleh, Jopson et al.(1990, IEEE Photon Technol. Lett. 2, 714; 1991, Fiber Laser Sources …

We analyze the critical parameters in an optically-amplified WDM ring network. We find that
a ring can accommodate 27 nodes when incorporating an EDFA and a channel-dropping …
