Pupil Plane Multiplexing for Vectorial Fourier Ptychography

Laser &Photonics Reviews, EarlyView.
This study proposes a cost‐effective, modality‐adaptive multichannel microscopy framework using pupil‐plane multiplexing. A custom pupil aperture at the Fourier plane encodes channel‐specific transfer functions with spectral or polarization filters, and model‐based reconstruction with channel‐dependent priors decodes them.

General‐Purpose Hexagonal Programmable Photonic Integrated Circuit with a >30 GHz Free Spectral Range

Laser &Photonics Reviews, EarlyView.
A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Coherence‐Gated Mirau Interferometry for Single‐Shot Quantitative Phase Imaging and Motion Sensing

Laser &Photonics Reviews, EarlyView.
This paper presents a compact add‐on module converting a Mirau or other on‐axis interferometer into a single‐shot quantitative phase imaging system using coherence gating and precise optical path matching. Demonstrations include time‐resolved imaging of human cells and streaming red blood cells, visualization of evaporation dynamics in liquid mixtures,
