Periodically poled lithium niobate waveguides are an excellent source of photon pairs via spontaneous parametric down-conversion (SPDC) with applications in quantum computing, communication and sensing. For scalable quantum computing, one photon is detected to herald the presence of the partner photon. It is critical the quantum state of the heralded photon is pure without the need for spectral filtering. Standard periodically poled waveguides prepare photons that are highly correlated and are unsuitable for quantum computing. This project will develop Python software for simulating lithium niobate waveguides to predict the spectral properties of the generated photons, including optimizers and graphical interfaces. The goal is to design lithium niobate waveguides that can prepare pure heralded photons based on SPDC. This project will take place in the Optical Nanomaterial Group at ETH Zurich. - Optical Physics

Lithium niobate on insulator is a new photonics platform with excellent linear and nonlinear optical properties for quantum information applications. Quantum walks, based on arrays of coupled waveguides, enable the study of multi-modal quantum systems and are a platform for quantum simulation. Nonlinear optics, such as three-wave and four-wave mixing could add a new dimension to quantum walks enabling the study of richer physics. This project will focus on the simulation and design of waveguide array for linear optical applications, such as implementation of quantum gates, and then with nonlinear capabilities. A software package will be developed in Python to simulate linear and nonlinear quantum walks, and chip designs will be generated for fabrication. This project will take place in the Optical Nanomaterial Group at ETH Zurich. - Optical Physics

Endovascular stents (endografts) are used to repair aortic aneurisms within the blood vessel without open surgery. Self expanding endografts are composed of a Nitinol frame covered with a woven polyester material that is similar to the standard surgical grafts. For deployment, the grafts are loaded in so called catheters.

Smart sensors for real-time detecting gas phase substances are essential for a lot of potential application such as wearable electronics, intelligent diagnosis, environmental monitoring, etc. at the coming era of internet of things (IoTs). Flexible, transparent sensing devices will enable easier and more comfortable integration with other consumer electronics in our daily life. Ionic liquid, as an emerging sensing material, exhibits potentials with thier high sensitivity, excellent transparency, and intrinsic flexibility. Yet their poor selectivity towards various components hinders the wide application of those devices, where, therefore, research focus is desired. - Sensor (Chemical and Bio-) Technology

Wireless empowered micro/-nanorobotic systems enable novel and innovative medical therapeutics and diagnostics such as minimal-invasive surgery, targeted drug delivery, or enhanced imaging of diseased tissue. Immense research is conducted using various different external field-driven robot actuation methods, including magnetic, pneumatic, optical, and electric fields. Each technique brings its advantages and limitations that are matched for addressing one specific medical task. At the Acoustic Robotics and Systems Lab (ARSL), we focus on acoustically based robotic systems for life sciences and healthcare applications. Activation by ultrasound is attractive because ultrasound is safe to most biological systems, non-invasive, penetrates deep into the body of an animal model, and is widely spread in clinical institutions. - Biology, Engineering and Technology, Physics
