In-silico clearing refractive index tomography.

The authors achieve ultrahigh resolution and depth volumetric imaging in complex media by recording a volumetric reflection matrix covering individual wavelengths and angles and developing reconstruction algorithms based on volumetric wave correlation.

Optical Ising machines provide a promising approach to solve complex optimization problems and hence are of broad interest in physics society. This paper constructs a nonlinear optical Ising machine with spatial light modulators to find distinct phase transitions, which demonstrates a platform for solving optimization problem in more efficient way.

The combination of optical phase conjugation and light amplification enables wavefront shaping with simultaneously optimized operational speed, number of control degrees of freedom and energy of the focused wavefront. Shaping with a 10 μs latency time over about 10⁶ control modes and energy gain approaching unity is demonstrated.
