Welcome to ComLab (Communications Laboratory), a leading research hub within the Department of Communications at the School of Electrical and Computer Engineering (FEEC) of the University of Campinas (Unicamp). Our laboratory is dedicated to cutting-edge research in communication systems and networking, with a strong emphasis on digital signal processing, optical communications, and enabling technologies for the 6G era. With a solid history of collaboration with industrial partners and prestigious international institutions, ComLab is at the forefront of developing solutions for ultra-high-speed data transmission, machine learning, distributed optical sensing, and quantum technologies.
Our research infrastructure is anchored by the EMU-AltaVe laboratory, a state-of-the-art facility funded by FAPESP, providing advanced instrumentation that is unique in Latin America. The lab is equipped with high-bandwidth oscilloscopes (80 GHz), arbitrary waveform generators (70 GHz), and ultra-narrow linewidth lasers (< 100 Hz). This technical base enables complex experimental setups with coherent reception and the validation of algorithms in real-world scenarios using the deployed underground fiber network across the Unicamp campus. ComLab’s global prominence is reflected in its high-impact publications and leadership in global forums.
