The main hindrance to optical imaging at elevated depths is the scattering of light exhibited by biological tissues. Consequently, various wavefront shaping techniques have been developed in order to achieve focusing in scattering media. In our scattering compensation experiments, the spatial light modulator is replaced by a novel integrated photonics-based wavefront shaper. We work on focusing through a static scatterer using near-infrared light. The photonic integrated circuit (PIC) used in this research consists of a 1D array of optical emitters with independently controlled phases. This PIC-based wavefront shaper was fabricated on a CMOS-compatible platform offering the prospect of large-scale fabrication.
