Abstract
Current and wavelength characteristics for 1.55-μm semiconductor optical amplifiers (SOAs) containing bulk active layers with various tensile strains were investigated. The strain dependence of the gain-difference between TE-mode and TM-mode (ΔG TE-TM) was almost linear having the waveguide-width over 0.8-1.5 μm. A -0.12% tensile-strained bulk SOA had very low ΔG TE-TM of less than 0.8 dB ranging the driving current from 0 to 120 mA. The low-polarization-sensitive condition of SOA with a strained-bulk active layer was shown to have very wide range in driving current and wavelength for the network device application.
