Semiconductor optical amplifiers (SOAs) leverage semiconductors as the gain medium to increase optical launch power, compensating for the loss of optical power in other optical devices. Primarily seen in telecommunication systems as Fiber-Pigtailed components, these components operate at signals with wavelengths between 0.85 and 1.6 micrometers (1 micrometer = 0.000001m). For compensating the loss, the […]
