“…Therefore, SOAs have been widely used in optical communication systems, sensing systems and all-optical processing technologies, etc. [2] Many alloptical active components have been developed based on the nonlinear effect of SOAs, such as all-optical wavelength converters, [3] all-optical flip-flops, [4] alloptical logic, [5,6] all-optical clock recovery [7] and alloptical buffers. [8−11] However, the electro-optical conversion efficiency of SOAs is very low, and the E-O conversion efficiency of existing SOAs is lower than 15%, indicating that the energy consumption of SOAs is very high.…”

The internal optical loss in semiconductor optical amplifiers (SOAs) is investigated experimentally and theoretically over a wide injection current range. A new measurement method is proposed without noise figure spectra. Theoretically, considering the internal loss in an SOA, a modified formula of the input-output characteristics is deduced. Based on the practically measured input-output characteristic curves, the internal loss coefficient of an SOA is measured at different injection currents. The results demonstrate that the internal loss coefficient of SOAs decreases with increasing injection current.
