LESSON PACKET / SA-KNOW-PHOTONICS-001

Follow the photon before claiming a device.
Device / Photonics

Photon energy, emission, detection, resonant transfer, and phase modulation belong to one causal chain, but each step needs a different material, solver, coupling, and measurement contract. This packet keeps the equations useful and the missing evidence visible.

EVIDENCE SEQUENCE

What the learner should inspect first.

This surface connects the daily-scan source signal to an original SemiAgora simulation object without copying source text, code, figures, PDK files, or process recipes.

01

Convert vacuum wavelength to photon energy with exact NIST SI constants, then declare the semiconductor material evidence that is still missing.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
02

Separate an LED ceiling proxy from the symbolic laser-threshold condition; neither is a calibrated emitter-performance prediction.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
03

Read ideal one-electron responsivity as a conversion relation, not proof of absorption, collection, dark current, bandwidth, solar efficiency, or calibration.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
04

Use the scalar all-pass ring response to see coupling and phase sensitivity, then name dispersion, mode, bend-loss, backscatter, and measurement replacement evidence.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
05

Use assumed delta-n to move MZI phase and normalized output while keeping the carrier model, junction, voltage, loss, bandwidth, and energy calculation blocked.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

METHODS

Precomputed model contract.

The goal is useful study scaffolding and paper-planning discipline, not calibrated production evidence.

method

Deterministic 4 x 3 x 2 x 3 x 3 x 21 sweep over spectral context, assumed external QE, emitter evidence state, ring coupling, assumed delta-n, and wavelength.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

Exact h, c, and e are cited from NIST; every device-like value is labeled as an original illustrative input rather than an external performance value.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

Official courses, documentation, laboratory publications, and primary-paper metadata are linked without mirroring source text, figures, tables, charts, or course files.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

LIMITS

Useful, but deliberately bounded.

No account, upload, payment, comment, newsletter, live solver, facility workflow, or product-release surface is enabled.

non-claim

No semiconductor absorption or gain, recombination, laser threshold current, solar detailed balance, dark current, noise, thermal, lifetime, or calibrated detector/emitter model.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

No Meep, FDTD, mode solver, carrier model, TCAD, SPICE, optimizer, upload parser, or live server execution.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

No ring Q or insertion-loss claim, modulator Vpi, bandwidth, energy-per-bit, foundry process, fabrication recipe, device ranking, product recommendation, or qualification claim.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

SOURCE ANCHOR

Link-only public source spine.

SemiAgora uses the source as a signal and citation anchor, then writes original summaries and original toy data with explicit limitations.
