| Summary:
Cosmic neutrinos are unique probes of the high energy universe. IceCube has
discovered a diffuse astrophysical neutrino flux since 2013, but their origin
remains elusive. The potential sources could include, for example, active
galactic nuclei, gamma-ray bursts and star burst galaxies. To resolve those
scenarios, higher statistics and better angular resolution of astrophysical
neutrinos are needed. An optical module with larger photon collection area and
more precise timing resolution in a next generation neutrino telescope could
help. Silicon photon multipliers (SiPMs), with high quantum efficiency and fast
responding time, combining with traditional PMTs, could boost photon detection
efficiency and pointing capability. We will present a study on exploring the
benefits of combining multiple PMTs and SiPMs in an optical module.
