Carrier lifetime and linewidth-enhancement-factor measurements for semiconductor optical amplifier using four-wave mixing effect

Not Accessible

Your library or personal account may give you access


We propose a new technique for measuring the carrier lifetime (τ) and the linewidth enhancement factor (α-parameler) in a traveling-wave semiconductor optical amplifier (TW-SOA) under cw conditions. Experimental results verify that the method enables us to evaluate τ and α as a function of wavelength and injection current to the TW-SOA.
