Abstract
We present a detailed analysis of three-dimensional photonic band-gap materials consisting of lattices of slanted pores with n = 2 , 3, and 4 pores per unit cell. These slanted pores emanate from one or two masks consisting of a two-dimensional square or triangular lattice of holes placed on the top surface of the crystal. We also consider the case in which the top surface is "polished" at an angle after the first set of slanted pores is generated from the first mask. A second set of slanted pores is then generated from a second mask placed on the new angled surface. Using these architectures, we demonstrate photonic band gaps of up to 25% of the gap center frequency when the crystal is made from materials with a dielectric constant ratio of 11.9:1 (silicon with air pores). The proposed structures are amenable to microfabrication using established techniques such as x-ray lithography or two-photon direct writing in a polymer template, followed by inversion and replication of the template with polycrystalline silicon. They can also be microfabricated by direct plasma etching in single crystal semiconductors. An alternative fabrication protocol consists of photoelectrochemical etching of deep pores in a single crystal semiconductor followed by focused ion beam or reactive ion etching of the second lattice of directed pores.

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; both teacher heads agree on what is shown here.
