Photonics chip allows light amplification
Scientists at EPFL have developed photonic integrated circuits that demonstrated a new principle of light amplification on a silicon chip. It can be employed for optical signals like those used in Lidar, trans-oceanic fiber amplifiers or in data center telecommunications.
Urban planning helps mitigate extreme weather effects in Haut-Valais
Olivier Lalancette, an EPFL Master’s student in architecture, has come up with some development proposals for the Brig-Visp-Naters conurbation. His suggestions, relatively modest in scope, could help these cities better withstand the droughts and heavy rainfall that are expected to intensify by 2050. Lalancette hopes his study will start a conversation about the region’s future.
