Characterization of a multifunctional active demultiplexer for optical frequency combs [PDF]
, 2020 We report on a multifunctional active demultiplexer for optical frequency combs. The proposed technique, based on injection locking, combines the functionality of a tunable demultiplexer, gain equalizer and an optical amplifer, all in one device ...

Spatiotemporal Thermal Modulation and Patterning using a Programmable 1024 Element Microheater Array
Advanced Science, EarlyView.Programmable microheater arrays are essential for a variety of applications. However, large arrays have thus far not been realized. We introduce a programmable 32×$\times$32 microheater array consisting of heating elements – each smaller than 300 μm$\umu{\rm m}$.

Single‐Step Analog In‐Memory Matrix Computation in Three‐Dimensional Circuits
Advanced Intelligent Systems, EarlyView.A wooden model illustrates a 3D memristive array designed for single‐step kernel convolutions. It shows how two‐dimensional input data are mapped into the 3D array and convolved in parallel with stored kernels. Color‐coded connection points represent programmed memory‐element values, with each color corresponding to a specific kernel weight.
