Optics

Scientists at EPFL, ETH Zurich and Harvard Medical School/Boston Children’s Hospital have developed an implantable technology that enabled the discovery of an interaction between sensory neurons and immune cells.

EPFL physicists propose a new path to detect infrared radiation with outstanding sensitivity, allowing detection of signals as low as that of a single quantum of light.

Researchers from EPFL's Photonics Systems Lab have come up with a way of reconfiguring microwave photonic filters without the need for an external device. This paves the way for more compact, environmentally friendly filters that will be more practical and cheaper to use. Potential applications include detection and communications systems. The researchers' findings have recently been published in Nature Communications.

In a promising breakthrough for the future of communications, EPFL researchers have developed a technology that can amplify light in the latest hollow-core optical fibers.

EPFL researchers have invented a way of automatically working out what data needs to be put into a complex system – such as a fiber optic network – in order to get the desired result. Their solution could prove especially useful in robotics, medicine and image projection.

Summer Series: Science as a vocation. Christophe Galland, the head of EPFL’s Laboratory of Quantum and Nano-Optics, believes that teaching and research are inextricably linked. Let’s find out more about this physicist who’s eager to share his passion.
