In recent years, various developments have advanced the field of optical sensors based on single-photon avalanche diodes. In this contribution we present two sensors that were designed in 0.35μm CMOS technology. A silicon photomultiplier achieves a fill factor of 68 % at 50 μm pixel pitch and allows improved functionality by cointegration of application-specific readout electronics. A time-gated line sensor with gating times down to 1.5ns and serial digital output was designed based on optimized pixel geometry suitable for spectroscopy applications. Planned further improvements of sensors based on single-photon avalanche diode technology, including on-chip temperature compensation, are presented
