摘要： An optical amplifier has two amplifying sections formed in a semiconductor structure. The two amplifying sections have different ratios of gain for two polarization states (e.g., TE and TM). Thus the amplifier as a whole has a gain ratio determined by the gains of the two amplifying sections. The two amplifying sections are separately electronically controllable so as to control the gains of the two amplifying sections and thus the gain ratio of the amplifier as a whole. Such an amplifier can be made by quantum well intermixing.
