SOA, what kind of optical amplifier is a semiconductor optical amplifier?
Historically, these great men started the flying mode of optical communication.
1. In 1960, Maiman invented the first ruby laser (T253 T261V2.0)
2. In 1962, Lebedev of the Soviet Union and four American units all developed a homojunction laser
3. In 1966, Kao Kun's paper proposed that low-loss glass fiber can be used for optical communication (T304)
4. In 1966, Bell Labs was still working on homojunction lasers
5. In 1970, R.Maurer, D.Keck and P.Schultz of CORING realized the low-loss fiber; in the same year, the research on the heterojunction laser at Bell Labs was completed
Then, the semiconductor optical amplifier also shines on the stage. The fox-li model of Li Dingyi's resonant cavity model has laid the foundation for FP laser and FP-SOA, and has made outstanding contributions.
In 1983, SOA semiconductor optical amplifier was born, classified as Fabry-Perot semiconductor optical amplifier (FP-SOA) and traveling wave semiconductor optical amplifier (TW-SOA).
Let's take a look at the difference between FP-SOA and TW-SOA:
FP-SOA
TW-SOA
Please look forward to more industry science!
