Broadband achromatic metalens focuses light regardless of polarization

Broadband achromatic metalens focuses light regardless of polarization

In this work, we show that anisotropic nanofins can be used as a building block to realize achromatic as well as polarization-insensitive metalenses. These metalenses …

 

Meta-surface corrects for chromatic aberrations across all kinds of lenses

Meta-surface corrects for chromatic aberrations across all kinds of lenses

In a new work, we show that dispersion engineering of metalenses can be used to correct the aberrations of traditional optical elements, including complex objective …

 

Nano-optic endoscope for high-resolution optical coherence tomography

Nano-optic endoscope for high-resolution optical coherence tomography

In recent published work, we have shown that a metalens may be directly integrated with an endoscope to improve the resolution of optical coherence tomography …

 

Ultrasensitive 3D force spectroscopy detects unambiguously exotic force on a particle in an evanescent field

Ultrasensitive 3D force spectroscopy detects unambiguously exotic force on a particle in an evanescent field

It was predicted in recent years that a non-chiral particle in an evanescent optical field (such as one generated by total internal reflection) is able …
