A compact, low power, optically controlled, electroabsorption modulator (EAM) performing unconstrained wavelength conversion up to 2.5 Gbit/s was demonstrated. The compact size, low optical and electrical power requirements and electrical reconfigurability allowed for single chip implementation of two-dimensional arrays of multichannel wavelength converters. By appropriately presetting its dc bias points the EAM was designed to efficiently modulate wavelengths over the C band. The results show that through appropriate optimization of the electroabsorption properties of the EAM multple-quantum wells and reduction in size of the on-chip resistors, photodetector and EAM capacitances high-speed operation of these devices at 10 Gbit/s was possible.
