Abstract :
Summary form only given. We have demonstrated a new device concept; by introducing a resonant tunnelling diode (RTD) to an optical waveguide, an InAlGaAs-InP electroabsorption modulator can be integrated with a high bandwidth electrical amplifier. The results are an early indication that the device does have a large bandwidth-to-drive-voltage ratio due to the electrical gain and a large modulation bandwidth.
