Semiconductor Plasmonic Waveguide Confinement Factor Calculator
Integrate actual caller physically appropriate dispersive modal energy density over observed cell volumes/region flags, not simple geometric volume fraction or naive ε|E|² in metals.
Description
Modal confinement is an energy-weighted regional fraction rather than a geometric volume fraction.
Modal confinement is an energy-weighted regional fraction rather than a geometric volume fraction.1
In a dispersive plasmonic system the energy-density definition must be established independently.
When to use Semiconductor Plasmonic Waveguide Confinement Factor Calculator
Use this tool when you need to reproduce the stated calculation from measured records or independently selected model inputs. Prepare measured device or specimen records under independently matched branch, temperature, frame, and unit conventions.
How to use Semiconductor Plasmonic Waveguide Confinement Factor Calculator and understand its results
- Prepare measured device or specimen records under independently matched branch, temperature, frame, and unit conventions.
- Enter observedRegionEnergyDensity, observedCellVolumesM3, callerPlasmonActiveRegionFlags, following the field table and rules below, then run the tool.
- Read energyWeightedPlasmonConfinementFraction. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedRegionEnergyDensity | Observed region energy density | list of number | Required |
| observedCellVolumesM3 | Observed cell volumes m3 | list of number | Required |
| callerPlasmonActiveRegionFlags | Caller plasmon active region flags | list of number | Required |
Use aligned nonempty nonnegative energy densities, positive cell volumes in cubic metres, and binary active-region flags. Multiply density by volume; require positive total energy; divide flagged energy sum by total. The tool does not derive a dispersive energy density from fields.
confinement=Σ(flag_i×density_i×volume_i)/Σ(density_i×volume_i) Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| energyWeightedPlasmonConfinementFraction | Energy weighted plasmon confinement fraction | number |

}Limitations and assumptions
Matched measurement branch, material state, calibration, and conventions must be independently established. Results do not certify device performance or operating conditions.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected. Evidence arrays must be dense, with no missing cells. Numeric observation lists allow at most 10,000 entries, subject to any smaller bounds stated above.
Alternative or Complementary methods
For a related review, use Semiconductor Plasmonic Propagation Length Vs Confinement Calculator: Confinement and propagation length can be compared as paired observations under two explicit criteria. Reporting qualifying samples and products keeps the evidence separate from a universal tradeoff law. For a complementary step, use Semiconductor Plasmonic Propagation Length Calculator: An intensity decay fit defines a plasmonic propagation length at the 1/e intensity level. Using intensity rather than field amplitude fixes the factor-of-two convention.
