Abstract :
The two sections of the amplifier were separately pumped with pulse currents and the device was characterized with a tunable CW diode laser. The spectral response of the equalizer built from 30 μm selective area growth (SAG) stripe region is shown together with a theoretical simulation. By varying the magnitude of the current in the short-wavelength section a spectral equalization is obtained over more than 100 nm range
