Beating bandwidth limits for large aperture broadband nano-optics
Johannes E. Fröch, Praneeth K. Chakravarthula, Jipeng Sun +10
Flat optics have been proposed as an attractive approach for the implementation of new imaging and sensing modalities to replace and augment refractive optics. However, chromatic a…
Non-volatile Phase-only Transmissive Spatial Light Modulators
Zhuoran Fang, Rui Chen, Johannes E. Fröch +14
Free-space modulation of light is crucial for many applications, from light detection and ranging to virtual or augmented reality. Traditional means of modulating free-space light…
Large FOV short-wave infrared meta-lens for scanning fiber endoscopy
Ningzhi Xie, Matthew D. Carson, Johannes E. Fröch +3
The scanning fiber endoscope (SFE), an ultra-small optical imaging device with a large field-of-view (FOV) for having a clear forward view into the interior of blood vessels, has g…
Foveated Thermal Computational Imaging in the Wild Using All-Silicon Meta-Optics
Vishwanath Saragadam, Zheyi Han, Vivek Boominathan +7
Foveated imaging provides a better tradeoff between situational awareness (field of view) and resolution and is critical in long-wavelength infrared regimes because of the size, we…
