Infrastructure

ComLab’s research capabilities are anchored by the EMU-AltaVe (Multi-User Equipment for Ultra-High-Speed Data Transmission) facility. This state-of-the-art laboratory was established through a strategic investment from FAPESP (São Paulo Research Foundation), making it one of the most advanced laboratories for optical communications and sensing in Latin America.

Key Technical Capabilities

The laboratory is equipped with world-class instrumentation designed for high-precision experiments:

• Ultra-Narrow Linewidth Lasers: The facility features specialized lasers with an ultra-narrow linewidth of < 100 Hz, a critical requirement for high-sensitivity interferometric sensing and phase-coherent detection.

• High-Bandwidth Instrumentation: Our setup includes high-end Arbitrary Waveform Generators (AWG) with 70 GHz bandwidth and Coherent Optical Receivers coupled with real-time oscilloscopes reaching 80 GHz bandwidth and 256 GSa/s sampling rates.

A unique feature of ComLab’s infrastructure is the direct access to a dedicated network of deployed underground fiber optics spanning the Unicamp campus. This field-testing capability allows researchers to move beyond laboratory simulations, validating Digital Signal Processing (DSP) algorithms and anomaly detection models under real-world environmental conditions, such as urban vibrations and soil temperature fluctuations.
