Abstract

Abstract

Chromatic aberrations in lenses are challenging to correct over large bandwidth. We show that dispersion-tailored and polarization-insensitive metasurfaces comprising counterintuitive anisotropic nanofins can correct the chromatic aberrations simple singlet lenses to sophisticated microscope objectives with unprecedented compactness.

Abstract

Abstract

This work reports a normal incident high speed photodiode operating at two-micron wavelength with InGaAs/GaAsSb type-II multiple quantum wells absorber. A 3dB bandwidth of 25 GHz can be achieved, which is, in our knowledge, the fastest photodiode at 2-micron wavelength.
