A novel planar waveguide wavelength demultiplexer design for integrated optical triplexer transceiver
Bibliographic record
Abstract
A novel wavelength demultiplexer design is proposed for the development of integrated optical triplexer transceiver in fiber-to-the-home (FTTH) applications. Still taking the slab waveguide as the beam confining element along the vertical direction but following a different approach from the arrayed waveguide grating, we use planar lenses to convert the phase front and planar diffraction grating to split the collimated beams in different wavelengths. The planar lenses and grating are realized through the effective refractive index difference arising from the difference on the cladding layer thickness of the slab waveguide. In applications such as optical triplexer transceivers where relatively large wavelength spacing is required among signal channels over a broad wavelength range, this design seems more appealing on simulated performance and fabrication cost in comparison with various existing integrated structures. Preliminary simulation results have shown that this component, once integrated with laser diode and photodetectors, has the potential to reach the required specifications as the optical triplexer transceiver in optical network unit for FTTH applications.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
