Exoplanet Detection Using Adaptive Quantum-Optimal Measurement
Hyunsoo Choi, Hyoung Won Baac, Zubin Jacob +1
Detecting terrestrial exoplanets in the habitable zones of nearby stars remains a critical challenge. Such planets can be \(10^8\) to \(10^{10}\) times fainter than their host star…
Nyquist-Sampled Time-Domain Adjoint FDTD for Memory-Efficient Broadband Nanophotonic Inverse Design
Mingyu Park, Owen D. Miller, Haejun Chung
Adjoint optimization is a cornerstone of broadband nanophotonic inverse design, but conventional time-domain implementations face a severe memory bottleneck because they retain for…
Design parameters of free-form color routers for subwavelength pixelated CMOS image sensors
Sanmun Kim, Chanhyung Park, Shinho Kim +2
Metasurface-based color routers are emerging as next-generation optical components for image sensors, replacing classical color filters and microlens arrays. In this work, we repor…
Inverse Design of High-NA Metalens for Maskless Lithography
Haejun Chung, Feng Zhang, Hao Li +2
We demonstrate an axisymmetric inverse-designed metalens to improve the performance of zone-plate-array lithography (ZPAL), one of the maskless lithography approaches, that offer a…
Tunable metasurface inverse design for 80% switching efficiencies and 144 angular steering
Haejun Chung, Owen D. Miller
Tunable metasurfaces have demonstrated the potential for dramatically enhanced functionality for applications including sensing, ranging and imaging. Liquid crystals (LCs) have fas…
High-NA Achromatic Metalenses by Inverse Design
Haejun Chung, Owen D. Miller
We use inverse design to discover metalens structures that exhibit broadband, achromatic focusing across low, moderate, and high numerical apertures. We show that standard unit-cel…
Maximal Free-Space Concentration of Electromagnetic Waves
Hyungki Shim, Haejun Chung, Owen D. Miller
We derive upper bounds to free-space concentration of electromagnetic waves, mapping out the limits to maximum intensity for any spot size and optical beam-shaping device. For sub-…
