Nanophotonic polarization diversity demultiplexer chip

, 2009
We demonstrate a very compact multifunctional photonic-crystal demultiplexer on high index contrast InP-membrane for coarse WDM applications. Polarization diversity is implemented using 2D-grating couplers.

An ultra-compact dual-channel multimode wavelength demultiplexer based on inverse design

Results in Physics, 2021
An ultra-compact multimode wavelength demultiplexer (MWD) with a footprint of 3.6 × 2.4 μm2 was designed. Its size is approximately two orders of magnitude smaller than the size of the traditional waveguide-based device.

Real‐Time Multicolor Fluorescence Microscopy via Cross‐Channel Acquisition and Deep‐Learning‐Based Inference

Advanced Intelligent Discovery, EarlyView.
Sequential multicolor fluorescence imaging in dynamic microsystems is constrained by acquisition speed and excitation dose. This study introduces a real‐time framework to reconstruct spectrally separated channels from reduced cross‐channel acquisitions (frames containing mixed spectral contributions).
