Master’s student position
Machine learning with photonic neural networks
Artificial intelligence (AI) is the ability to perform tasks that are generally associated with intelligent beings. Recently, bio- and neuro-inspired (neuromorphic) algorithms have attracted considerable attention with their ability to extract structure and knowledge from huge unstructured data sets. To execute these new algorithms efficiently at the large scale required in datacenters or, for example, to interpret sensor data locally in embedded, very low-power devices, we need novel neuromorphic compute architectures and hardware.
At IBM Research – Zurich, the Neuromorphic Devices & Systems group is working on implementing a neural network based on integrated silicon photonic technology. We recently developed integrated, multi-level optical synaptic elements that will be embedded in an all-optical neural network (see image). Before we can do that, however, we need a better understanding of the electro-optic properties of these synaptic elements.
Scope of this Master’s thesis
We will adapt the focus of the thesis based on your interests. Possible topics include:
- Characterization of weighting elements: Measurement of device transmission. Set up and perform electro-optical measurements and analyze your measurement results.
- Design an interface between hardware and software to control multiple weighting elements in parallel. This involves programming of microcontrollers or FPGAs.
- Device and system simulations.
- High-speed electro-optical measurements.
We are seeking a candidate with a strong interest in integrated optics. Prior experience in microcontroller programming, object-oriented programming and/or optical characterization is a plus. You should be enrolled as a student at ETH Zurich. For this project you should be available for a period of at least 6 months starting in spring 2019.
