The article titled "Inverse Design of Photonic Systems" by Benjamin MacLellan and co-workers presents a framework for identifying optimal topologies and operational parameters for photonic systems. The method utilizes automatic differentiation and discrete topological changes to explore...
Millimeter-wave and terahertz integrated circuits and chips are expected to serve as the backbone for future wireless networks and high resolution sensing. However, design of these integrated circuits and chips can be quite complex, requiring years of hu
Most of the existing literature focuses on miniaturizing the optical detection; little attention is directed to on-chip optical excitation. In this work, we design a metasurface to create a planar integrated photonic source beam collimator for use in on-chip optofluidic sensing applications. We use...
Inverse design has revolutionized the field of photonics, enabling automated development of complex structures and geometries with unique functionalities unmatched by classical design. However, the use of inverse design in nonlinear photonics has been limited. In this work, we demonstrate quantum and clas...
Photonic surfaces designed with specific optical characteristics are becoming increasingly crucial for novel energy harvesting and storage systems. The design of these surfaces can be achieved by texturing materials using lasers. The optimal adjustment of laser fabrication parameters to achieve target surface...
Also, since the inverse-design framework is a system as well, the experience and knowledge of experts can hardly affect the intended design after the inverse-design system is constructed. Such an approach with inverse design has been studied for the discovery of new photonic devices (Jiang and ...

(2D) inverse-design method based on the effective index approximation with a low-index contrast constraint. This results in compact amorphous lens systems that are generally feed-forward and low-resonance. We designed and experimentally demonstrated a vector–matrix product for a 2 × 2 matrix...
Using photonic inverse design, reflector structures interfaced to a standard, single-mode rectangular wave- guide were designed to form a high-Q, dispersion- engineered FP cavity (see Fig. 1a and Inset 1); intensity and phase of the reflected mode determine Q-factor and group velocity ...
we use inverse design by topology optimization to devise a generic design framework for developing power splitters in any material platform, although we focus the present work on silicon photonics. We report on the design, fabrication, and characterization of silicon power splitters and explore varying...
