Webstrong dependence of bandgap absorption on wavelength, the total absorption at 1.3 m is already much greater than that at 1.55 zm. Because of the fairly weak decrease of free car-rier absorption with wavelength (X2), at most a 3O% decrease in absorption coefficient is. expected at some intermediate wavelength between 1.3 and 1.55 1tzm.
