In a recent breakthrough published in Nature Photonics, a high-efficiency, high-bandwidth spatial light modulator (SLM) has been developed. The work, led by Chris Panuski and prof. Dirk Englund at the Massachusetts Institute of Technology, demonstrates a proof-of-principle device based on an array of photonic crystal microcavities with all-optical control of the resonance frequencies of each individual cavity. A key innovation was the cavity design, which was optimized simultaneously for high spatial confinement, high quality factor and high directionality of the...

(Approximate reading time: 5mins) Imagine we would like to simulate the flow of air around the wing of an airplane in order to calculate forces such as drag and lift, which are necessary for design purposes. Typically, we would use CFD (computational fluid dynamics) which uses an imported mesh, along with other inputs such as freestream velocity and angle of attack to simulate the flow around the wing. Then, the results are postprocessed to calculate the forces of interest. This...
