Artist’s view of a fully-integrated chip-scale OCT system.

Caption

The system integrates a III-V semiconductor light source, SiN-based interferometers, Si-Ge photodetectors (PDs), and an integrated ball-lens microprobe, thereby combining the distinct advantages of multiple photonic integration platforms. The insets illustrate complementary technologies that can be incorporated to realize a miniaturized, fully integrated OCT system. Abbreviations: ADC, analog-to-digital converter. Inset 1: Foundry-scalable embedded III-V lasers on silicon-on-insulator (SOI) wafers. Inset 2: Chip-based SiN tunable delay lines.
