Wafer-level packaging of three-dimensional MOEMS device with lens diaphragm
Bibliographic record
Abstract
This paper presents wafer level packaging of a miniature MOEMS monochromator for biomedical spectroscopy. Optical microlens and piezoelectrically-actuated diffraction grating are fabricated, and packaged at a wafer level into a complete, integrated monochromator with a fiber input. The packaged monochromator is an optical and mechanical system derived from a macroscale Czerny Turner monochromator. It integrates an angled mirror for folding and directing the input light path. A lithographically-defined reflective diffraction grating accepts and spectrally separates the input light from a fiber that is inserted into the built-in groove. The diffracted light is then collected through a diaphragmsuspended microlens and spatially separated on its path towards the output of the system. The packaging, done via encapsulated silicon cavities, provides batch processing and finishing of the complete device. The MLD is characterized with a Gaussian beam propagation model and the SSC packaged device is measured by its resolution and stray light through profiling with a CCD array.

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.
