Abstract :
Semiconductor optical amplifiers (SOAs) are often used in fiber-optic systems in which device gain must be adjusted precisely without disturbing the surrounding system. We have developed an unobtrusive technique for measuring SOA gain based on the peak wavelength of the device´s amplified spontaneous emission spectrum. This methodology also expedites gain measurements for systems in which an SOA dynamically switches on and off. We further confirm the reliability and robustness of this methodology
