The optical manifold has multiple cores that each generates an outgoing LIDAR signal that carries one or more channels. Scanning heads are located apart from the manifold. Each scanning head is associated with one of the cores and is configured such that each scanning head receives an outgoing LIDAR signal from the associated core. The scanning heads are each configured to transmit one or more LIDAR output signals that each carries light from a different one of the channels and such that the different LIDAR output signals each travels away from the scanning head in a different direction. Each of the cores is associated with different core electronics. The core electronics are configured to tune a property of one of the outgoing LIDAR signals such that the tuning of the property causes a change to the direction that the one or more LIDAR output signals travel away from the scanning head associated with the core electronics.

An architecture for an optoelectronic oscillator uses Stimulated Brillouin Scattering (SBS) to seed, filter and amplify the oscillation signal in an overlapped oscillator loop for both a RF modulated optical sideband and a SBS signal. By phase matching the RF modulated optical sideband generated by SBS with the SBS signal, the feedback will collapse the bandwidth of the SBS signal and in turn the bandwidth of the Brillouin frequency signal, which also serves as a filter to filter out multiple undesired OEO loop modes. The embodiments herein result in reduced phase noise and increased stability.
