Consider an InGaAsP semiconductor optical amplifier that has the following parameter values:
If a 100-mA bias current is applied, find ( a ) the pumping rate R p ( b ) the maximum (zero- signal) gain, ( c ) the saturation photon density, ( d ) the photon density if a l- W signal at 1310 nm enters the amplifier. Compare the results of ( c ) and ( d ).

Explanation
(a) From Eq. (11.2), the pumpi...
