The NRAO CDL photonics technology development program began during the ALMA development phase (see ALMA Support-Photonic Reference).  Microwave photonics technologies provided wide tuning bandwidths, which together with flexible fiber optic distribution, allowed for remotely located, low-phase-noise photonic local oscillators sourced needed for ALMA.
