Resonant microtaper leaky-mode computational spectropolarimetry with tens of femtometers spectral resolution and full Stokes measurement

on a sub-square-millimeter random medium. The proposed theoretical model clarifies the key factors governing the performance of computational measurement systems based on random media and may inspire the design of advanced computational measurement systems for optical field. The demonstrated RLM spectropolarimeter offers a potential approach for highly integrated, high-performance multi-dimensional optical field measurement.
