Proposal and demonstration of a symmetrical npipn electroabsorption modulator

We propose a new type of electroabsorption modulator based on a npipn diode structure. Its transmission curve versus applied bias should be symmetrical with respect to zero bias. A npipn InGaAs-InAlAs multiple-quantum-well (MQW) modulator has been fabricated to experimentally demonstrate two applications for optical fiber transmission systems: pulse generation with adjustable duty cycle for optical time division multiplexing and harmonic generation up to 40 GHz for millimeter radiowave transport on optical fiber.<
