Paper Abstract

Efficient InAsP/GaInP multiple-quantum-well electroabsorption waveguide modulators have been developed at 1.3 micrometers wavelength. The modulators exhibit a typical fiber-to-fiber optical insertion loss of 7 dB, a slope efficiency of 1.0 V-1, and an optical saturation intensity in excess of 10 mW. The 3 dB electrical bandwidth is dictated by the device capacitance and a 13 GHz bandwidth has been measured for a 3 micrometers wide 180 micrometers long modulator. In a microwave photonic link without amplification, a RF link gain as high as -31 dB is achieved at 0.9 mA photodetector current and 1 GHz subcarrier modulation frequency.
