Abstract
A gain-tunable semiconductor optical amplifier (10) includes an amplifying section (38) for amplifying an optical signal (422). A first tunable reflector section (51) and a second tunable reflector section (52) are integrated on opposed sides of the amplifying section (38) to reflect the optical signal at a clamping wavelength and to change an internal gain level to cause a stimulated emission at the clamping wavelength above the internal gain level.
