Thermo-optical phase shifters (TOPSs) have emerged as an important building block in
silicon photonics platforms due to their ability to dynamically control the optical phase of …

Spatially incoherent light sources, such as spontaneously emitting atoms, naively require
Maxwell's equations to be solved many times to obtain the total emission, which becomes …

As a sensing method with single molecule-level resolution in theory, surface-enhanced
Raman scattering (SERS) shows robust applications in wide fields. However, due to …

We present a general framework for inverse design of nanopatterned surfaces that maximize
spatially averaged surface-enhanced Raman (SERS) spectra from molecules distributed …

Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive and molecule-specific
