A team including researchers from the Department of Physics at ETH Zurich found a method for creating electrically defined quantum dots with the potential for long-sought tunability and scalability.

We spoke with Jonathan Home, our current Head of the Department, on becoming a Fellow of the American Physical Society (APS) and about his career, motivations and goals.

Using a random walk generated by modulating a ring quantum cascade laser, researchers from the Institute for Quantum Electronics at ETH Zurich have realised a new type of frequency comb.

The two researchers, who are members of the Institute for Quantum Electronics, were both awarded SNSF Starting Grants.

In a feat of optical waveguide engineering, researchers from the Institute for Quantum Electronics at ETH Zurich have successfully observed terahertz solitons in a ring quantum cascade laser.

Thanks to a collaboration between the Department of Physics at ETH Zurich and Technorama, visitors to the Science Centre can see with their naked eye very small objects that behave according to the unfamiliar laws of quantum mechanics – single atoms.

Absorption of light adds energy to a material. The electrons inside the material can react collectively or independently to that energy. Here, the dominant reaction pattern should not depend on perspective. However, in compound semiconductors, surprisingly, divergent responses are obtained depending on which atomic constituent is consulted. Knowledge of both perspectives is necessary to optimize new materials for applications in electronics and optoelectronics.

The ETH physicist has received an SNSF Consolidator Grant worth CHF 1.75 million.

EPFL researchers have collaborated with colleagues at ETH Zurich and Harvard University on a new thin-film circuit which, when connected to a laser beam, produces finely tailorable terahertz-frequency waves. The device opens up a world of potential applications in optics and telecommunications.
