This work presents an approach to multiple access for free-space laser communication (lasercom) called space-time division multiple access, which aggregates traffic from multiple users at the network edge. The objective is to share resources to lower

The performance of Nd3+-doped fiber amplifiers is limited by strong excited state absorption (ESA) of the signal, even for fluorozirconate glasses where ESA prevents the important region below 1320 nm from being used. To quantify this and explore alt

Excited-state absorption (ESA) cross sections were determined for the 800-nm band of Er-doped, Al/P-silica fibers. The oscillator strength of the ESA transition exceeds that of the 800 nm, ground-state absorption (GSA) transition by a factor of appro

Pr3+-doped fluorozirconate fiber amplifiers have been demonstrated to provide net-gains higher than 25 dB in a broad band centered on the 1300-nm communication window [1,2]. We have developed a quantitative numerical model and systematically analysed

Neodymium- and praseodymium-doped ZBLAN fluorozirconate glass are the most promising candidates for fiber amplifiers in the 1300-nm telecommunication window [1-3]. However, each suffers from serious problems that limit performance. We have examined t

The role of glass composition is examined theoretically and experimentally for fiber amplifiers. Simple analysis procedures can be used to set limits on performance and identify more favorable glass types for detailed investigation.

A comprehensive theoretical investigation of the 800-nm pump band for erbium-doped fiber amplifiers is presented. Both a silica and a fluorophosphate host are examined. To obtain the same amplification, the fluorophosphate requires 2–3 dB less pump

The performance of fiber amplifiers is extremely sensitive to the material-dependent properties of the pump band. High-power, reliable, low-cost diode lasers are currently only available at 800 nm, a poor pump band for Er3+ due to the low strength of

Despite the high level of activity in the area of Er-doped fiber lasers and amplifiers, questions still remain regarding the values of the absorption and stimulated-emission cross sections. The disagreement between experimental and calculated values

There has been a continuing interest in developing fiber amplifiers for the 1.3 μm window which is used for most optical communications traffic. Neodymium-doped fibers remain potential candidates for this function despite the problem of excited stat
