Tidy3D helps MIT researchers design a highly efficient spatial light modulator

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...
