Applications
BICs: bound states in the continuum (BICs) are special localized states that do not couple to the radiation spectrum. Very narrow angular 'splitting' can be observed in photonic bands, requiring direct, fine angle-resolved spectral characterization. PCSEL: after pumping a photonic crystal surface-emitting laser (Photonic Crystal Surface Emitting Laser, PCSEL), photonic bands emit fluorescence; above threshold, laser emission exits vertically at Γ. Fine angle-resolved spectral characterization of the fluorescence modes and laser emission is therefore required. Strong light-matter coupling: produces hybrid states with Rabi splitting. Their dispersion is key to such studies and requires microscopic angle-resolved spectral characterization.
Key Features
Based on FT-ARS technology: obtains microscopic angle-resolved spectra and accurately calibrates angular metrology using diffraction results from traceable standard gratings, achieving angular resolution as fine as 0.1°. Micrometer-scale sample-signal collection: a microscopic imaging architecture and spatial selection aperture support five-dimensional adjustment including detection-region scaling, translation and rotation. Vis-Nir broadband detection: band-specific aberration correction and dual optical paths with aberration elimination enable microscopic angle-resolved spectroscopy over 400~1650nm. Multiple angle-resolved measurement modes: combined illumination and collection conditions support 9 modes including transmission, reflection, emission and scattering. Millisecond transient spectral acquisition: FT-ARS with an imaging CCD captures hyperspectral angle-resolved spectra photographically, reducing acquisition time to milliseconds (~ms). Fully automated optical-path switching: motorized modules automatically switch full-angle, fixed-angle, transmission and reflection modes as well as the Vis and Nir channels. ARMS also reserves external-source input and signal-output interfaces for external light-source and microscopic spectral-output modules, supporting angle-resolved spectroscopy at low temperatures.
