Monolithically Integrated EPICs incorporating HBT Driver/Electroabsorption Modulator Arrays with Linearized Output and Wide Bandwidth

In this project Infinera will create a true Electronic-Photonic-Integrated-Circuit (EPIC) platform by including the necessary epitaxial growth and fabrication steps to incorporate a high-performance Heterojunction-Bipolar-Transistor (HBT) technology, together with a high-speed interconnect technology, to the current Photonic-Integrated-Circuit (PIC) process, without sacrificing the performance of current PIC devices. This EPIC platform will produce devices with performance beyond that capable from the hybrid integration of separate, high-performance, discrete electronic and photonic devices. The EPIC platform will also be developed with high yield and manufacturability in mind, sharing common epitaxial layers and processing steps between HBT fabrication and the standard PIC process, when possible, without reducing device performance. Infinera will research and develop the EPIC platform and utilize it to create a linearized, high-bandwidth transmitter. The project will include the development of a number of circuit ideas for linearizing the transmitter that capitalize upon the unique capabilities of monolithically integrated driver and transmitter.
