<p>The amplifier has an active zone including a quantum dot structure with atoms possessing a ground state and an excited state, where the zone is arranged in a structured resonant cavity for resonating a wavelength corresponding to the ground state. A current generator controls the amplifier, and delivers a charge carrier current (I) that is constant and higher than saturation current (IS) of the ground state. An independent claim is also included for a semiconductor phase modulator for phase modulating a constant amplitude optical signal.</p> |
