A single-mode lead silicate optical fiber has been fabricated to permit lower-power all-optical switching. The core glass has a nonlinear index of refraction eight times that of silica. The loss of the fiber is less than 2 dB/m. Over 177pi of phase s

We have generated pulses as short as 4 psec at 1530 nm from a mode-locked erbium-doped fiber laser. The mode locker is a wide-bandwidth, lithium niobate guided-wave modulator, and the fiber laser is completely integrated. We present evidence that sol

Diode lasers at 980 nm are a favored power source for Er-doped fiber amplifiers. Conditions of amplifier deployment require that the laser pumps be hermetically sealed and reliable for >105 hr. Many amplifier systems currently under design or test re

Excited-state-absorption and stimulated-emission cross-section spectra have been measured in the 1300-nm region for a wide variety of Nd3+-doped glass compositions. The results indicate that fluoroberyllates are the best choice for fiber amplifiers i

Distributed fiber amplifiers are being considered as an alternative to discrete fiber amplifiers.1 The gain in the distributed amplifier typically is envisioned to make up for the passive loss of the fiber, to form a lossless link. In this paper, the

Since nearly all optical fiber systems operate at 1300 nm, there has been a continuing effort to develop fiber amplifiers for this wavelength with performance approaching that of erbium amplifiers. Nd3+ is one of the most promising dopants for amplif

Increasing demand has caused substantial interest in high bit rate (> 5 Gbit/s) telephony systems, as reflected in emerging use of dispersion-shifted fibers for 1550 nm transmission in new system installations. However, the upgrading of existing stan

A strategy is presented for the dispersion-compensated, flexible upgrading of existing 1310 nm-optimised interoffice fibre networks by using an optical equaliser fibre for dispersion compensation, an erbium-doped fibre amplifier for loss compensation
