1Holographic planar lightwave circuit for on-chip spectroscopy显示文摘Computer-generated planar holograms are a powerful approach for designing planar lightwave circuits with unique properties.Digital planar holograms in particular can encode any optical transfer function with high customizability and is compatible with semiconductor lithography techniques and nanoimprint lithography.Here,we demonstrate that the integration of multiple holograms on a single device increases the overall spectral range of the spectrometer and offsets any performance decrement resulting from miniaturization.The validation of a high-resolution spectrometer-on-chip based on digital planar holograms shows performance comparable with that of a macrospectrometer.While maintaining the total device footprint below 2 cm2,the newly developed spectrometer achieved a spectral resolution of 0.15 nm in the red and near infrared range,over a 148 nm spectral range and 926 channels.This approach lays the groundwork for future on-chip spectroscopy and lab-on-chip sensing.Giuseppe Calafiore Alexander Koshelev Scott Dhuey Alexander Goltsov Pavel Sasorov Sergey Babin Vladimir Yankov Stefano Cabrini Christophe Peroz 2014Light(Science & Applications)2014,3,1:3
