Experimental Realization of a Handedness-Preserving Chiral Photonic Crystal Mirror
Bibliographic record
Abstract
Selective reflection and transmission of the different spin states of light have been a long-explored area in nanophotonics and quantum optics [1]. Applications are diverse and encompass many areas such as quantum information processing, engineering of light-matter interactions and novel types of lasers. Particularly, cold atoms interact more strongly with circularly polarized lights. One can envision making cavities in which only one spin state of light is trapped-but such cavities cannot be implemented with conventional, metallic or dielectric-stack mirrors as such mirrors flip the photon spin and, e.g., left-hand circularly polarized (LHCP) light becomes right-hand circularly polarized (RHCP) upon reflection. Here, we report on the first experimental observation of intrinsic chira-optical response with near perfect extinction in an ultrathin planar structure. The selective reflection is achieved via guided mode resonance (GMR) in a SiN photonic crystal membrane with a chiral pattern of the perforating holes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
