In this paper we report on a new silicon photomultiplier (SPM) architecture with additional signal output. This additional output has very fast single photo electron response (∼2 ns FWTM). This new device can be easily integrated into legacy systems by providing the ability to operate as a normal SPM with Anode readout or in new designs with an additional fast output. As result the rise time of timing signal for LYSO scintillator coupled to this new fast SPM is about 2ns, compared with typical 20-40ns for SPM's anode signal. This enables coincidence-timing performance improvements for SPM devices, from 300 ps (Coincidence Resolved Time - CRT - FWHM) to better than 250ps (CRT FWHM) coincidence timing resolution for SM series devices. Furthermore, use of the fast terminal allows for a wide range of leading thresholds without large degradation of CRT as compared with standard terminal. In this paper we will demonstrate that providing ability to detect first photon events provides significantly better CRT, comparable to large PDE improvement.
