Abstract: Metasurfaces comprise an array of pillars in a lattice. The dimensions of the pillars and the spacing are varied to obtain desired optical properties. The dispersionless metasurfaces can focus optical light over a broad wavelength range. Specific dispersion profiles for the metasurfaces can be designed. Gratings can be fabricated having similar properties as the array of pillars. Pillars in the metasurfaces can have different cross-section profiles.

Abstract: A solution containing a target molecule and a reference molecule is illuminated to obtain Raman signals. An optical metasurface is used as a diffractive optical element to split the Raman signal from the target molecule and the Raman signal from the reference molecule. The target and reference Raman signals can be detected at different locations with different photodetectors, and the target molecule concentration in the solution is determined by comparing the target and reference Raman signals.

Abstract: A retroreflector device is described, which includes a lens component operable for focusing radiation, which is incident thereto at an angle of incidence. The retroreflector also includes a mirror component operable for reflecting the radiation focused by the lens component back along the angle of incidence. The lens component and/or the mirror component includes a quasi-periodic array of elements, each of which comprises a dimension smaller than a wavelength of the radiation.

Abstract: Metasurfaces for polarimetric imaging are disclosed. The described devices are built to split and focus light to various pixels on an image sensor for different polarization bases. This allows for complete characterization of polarization by measuring the four Stokes parameters over the area of each superpixel, which corresponds to the area of the pixels on the image sensor.

Abstract: Compact optical devices such as spectrometers are realized with metasurfaces within a dielectric medium confined by reflective surfaces. The metasurfaces control the phase profiles of the reflected electromagnetic waves within the device. In a compact spectrometer, the metasurfaces within the device separate the electromagnetic waves in different wavelengths. The metasurfaces are designed according to their phase profile by varying the size of the array of scatterers.
