A metasurface is defined by an array of scattering elements having a U shape, where the geometrical dimensions determining the U shape are determined according to the different phase profiles that the metasurface is meant to generate in response to an incident electromagnetic wave. The metasurface, therefore, generates different phase shifts as a function of the incident electromagnetic wave.

Methods for attaching barcodes to polypeptides are provided. Methods for detecting molecular interactions at the single molecule level are provided. Embodiments of the invention are directed to a ONA barcoded protein array technology for parallel protein interaction profiling on a single molecule basis. DNA barcodes are attached to proteins collectively via ribosome display or individually via enzymatic conjugation. Novel methods are described herein that measure protein interactions based on the statistical analysis of co-localized polonies arising from barcoding DNAs of interacting proteins.
Plasmonic gratings, along with methods of creating devices using width-graded plasmonic gratings are described. Plasmonic gratings may be transmission-type or closed-ended plasmonic gratings, and may be disposed on detectors to enhance the spectral range detection of the detectors or in further device architectures.

Techniques and circuitry for wavelength monitor and control are disclosed herein. The disclosed wavelength monitor and control circuitry and techniques are designed to realize a multi-channel DWDM optical link by using a photonic receiver that dynamically adjusts resonant wavelengths of the microring drop filter (MDF), as needed. The wavelength monitor and control circuitry can monitor and control the resonant wavelengths of multiple MDFs for a DWDM silicon photonics receiver with minimum power and area overhead. In an embodiment, circuitry for an optical receiver comprises an MDF having resonant wavelength for multiple DWDM channels, and circuitry to control and monitor the resonant wavelength of the MDF in real-time and in manner that compensates for deviation between actual resonant wavelength of the MDF and the incident optical wavelength of the MDF.

Unleashing the power of quantum technologies at scale will depend heavily on the realization of quantum networks that can connect many hybrid quantum devices and platforms, exploiting each of their respective advantages. Entangled-photon sources and the subsequent manipulations required to link multiple nodes are critical to optimize the connectivity of optical quantum networks.
