Suppression of self-biased phototransistor effect in InP-based photonic modulators

The project relates to a key electro-optic component used in optical modems that route internet traffic between cities, countries, and continents. These high-bandwidth long-haul systems are also being evaluated to solve the problem of moving data between data centers and even within data centers for high-bandwidth applications such as cloud services and artificial intelligence. The transmitter in such systems must convert electrical signals from an application-specific integrated circuit (ASIC) to light signals which can be sent down an optical fibre. To increase the bandwidth of the electro-optic transmitter, a novel design has been proposed and patented by Ciena Canada. To ensure a path to commercialization, the new design must be explored both theoretically and experimentally with a depth and rigor not possible in an industrial environment. This project sets forth a set of research questions to answer, with simulation tools and sample devices provided by Ciena Canada.
