Optoelectronics

Prof. Dr. Valerio Pruneri

    Activities:

In the Optoelectronics group at the Institute of Photonic Sciences (ICFO), we study and develop new advanced materials and devices for the photonics industry. These include ultrathin materials, such as metals, graphene and phase change compounds for transparent electrode and optical switching, nano-structured glass surfaces for antifingerprint, antimicrobial and microfluidic applications, and low cost integrated optical sensors for cell counting, sorting, and DNA sequencing. The group aims at bridging the academic and industrial worlds by pursuing fundamental ideas with great potential for revolutionizing future photonic products. It thus works closely with local and international industrial organizations to make sure that the society at large benefits from its research effort in the future.
