    • The invention relates to a semiconductor optical amplifier, the construction of which is based on the production of semiconductor lasers and which is structured into multiple stages, comprising at least two active zones (1, 2) with gain which are separated by a passive zone (3) with controlled losses by means of a direct current (10) that is injected through the electrode (6). An electric modulation signal (5) with a first frequency (f1) is introduced through the first active zone (1), mixed with the optical signal (4) entering the device and amplified. The passive zone (3) attenuates the optical output signal from the first stage (11), such as to produce a second optical signal (12) which enters the second active zone (2) in order to be mixed with the electric signal (5) at a second frequency (f2). Finally, the optical output signal (13) is obtained with the frequencies added to each other (f1+f2), with the frequencies subtracted from each other (f1-f2) or with double each frequency (2f1, 2f2).
    • 半导体光放大器技术领域本发明涉及一种半导体光放大器,其结构基于半导体激光器的生产并且被构造成多级,包括至少两个增益被有源区(1,2)隔开的有源区(1,2) 3)通过经由电极(6)注入的直流电流(10)进行受控损失。 通过第一有源区(1)引入具有第一频率(f1)的电调制信号(5),与进入装置的光信号(4)混合并被放大。 无源区(3)衰减来自第一级(11)的光输出信号,以便产生进入第二有源区(2)的第二光信号(12),以便与电信号(5)混合 )以第二频率(f2)。 最后,通过彼此相加的频率(f1 + f2)获得光输出信号(13),其中频率彼此相减(f1-f2)或每个频率(2f1,2f2)加倍。
