Ultrasmall Silicon LED Enables High-Resolution Integrated Imaging
SINGAPORE, May 22, 2023 — Researchers at the Singapore-MIT Alliance for Research and Technology (SMART) developed a CMOS-based silicon LED that, though smaller than a wavelength, emits light at an intensity comparable to much larger silicon LEDs. In a separate study, the researchers used their LED as the illumination source in an in-line, lensless, centimeter-scale, all-silicon, holographic microscope. They also developed an untrained deep neural network to perform holographic image reconstruction. They then used
