Design of efficient high-order immersed metagratings using an evolutionary algorithm
Dhwanil Patel, Jacob de Nobel, Anna V. Kononova +2
Immersed reflection gratings improve spectral resolving power by enabling diffraction within a high refractive index medium. This principle has been widely adopted to make grating…

Theoretical performance limitations and filter selection based on Fisher information of a computational photonic crystal spectrometer for trace-gas retrieval
Marijn Siemons, Ralf Kohlhaas
As global climate change severely impacts our world, there is an increasing demand to monitor trace gases with a high spatial resolution and accuracy. At the same time, these instr…
