Abstract :
A 1.5 ¿m InGaAsP buried-heterostructure laser amplifier having small optical-mode confinement was fabricated with a Fabry-Perot cavity configuration. Its signal gain, saturation output power and noise characteristics were studied and found to be superior to those for AlGaAs amplifiers, as a result of small optical-mode confinement.
