Abstract

fetched live from OpenAlex

We present a theoretical roadmap for three-dimensional optical waveguide networks in holographically defined, diamondlike photonic band gap (PBG) materials. A fully 3D waveguide network is demonstrated through broadband $(100--200\phantom{\rule{0.3em}{0ex}}\mathrm{nm})$, single-mode waveguiding in air, coupled with sharp bends in three dimensions with minimal backscattering. Optimal waveguides in the in-plane $x$ and $y$ directions are shown to exhibit nearly $250\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ of single-mode bandwidth for light of wavelengths near $1.5\phantom{\rule{0.3em}{0ex}}\ensuremath{\mu}\mathrm{m}$. Vertical waveguide channels are formed by introducing air defects in a zigzag pattern. Realization of these circuit designs may be achieved through the combination of direct laser writing of defects within the holographically defined photoresist and the subsequent replication of the microchip template with a high refractive index semiconductor such as silicon.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
