  We discuss here new, enabling technologies for future photon-based neutrino
detectors. These technologies touch nearly every aspect of such detectors: new
scintillating materials, new methods of loading isotopes, new photon sensors
and collectors, new approaches to simulation and analysis, and new front-end
electronics and DAQ ideas. Of particular interest are technologies that enable
broad physics programs in hybrid Cherenkov/scintillation detectors, such as
slow fluors, water-based liquid scintillator, and spectral sorting of photons.
Several new large-scale detector ideas are also discussed, including hybrid
detectors like Theia, ArTEMIS, and generic slow-fluor detectors, as well as the
very different SLIPs and LiquidO approaches to instrumenting photon-based
detectors. A program of demonstrators for future detectors, including ANNIE,
Eos, and NuDOT are also discussed.
