Intensity

The Intensity detector produces four related views: Intensity, Angular Spectrum, Normalized Spectrum, and Normalized Angular Distribution. Together they describe the far-field emission intensity of the emissive structure across the spectral dimension, the angular dimension, and their normalized counterparts.

The Intensity detector is driven by in-layer emitters (EML) and is not affected by Incident Light, Incident Angle, P-Ratio, Cone Angle, or Incident Spectrum settings.

Spectrum

When Wavelength Mode is set to Sweep, the Intensity page shows far-field emission intensity (a.u.) vs. wavelength (nm) for each polarization channel.

Polarization: switch between TE / TM / Total using the polarization SelectButton. All three curves can be shown simultaneously, or a single curve selected via the legend.

Chart type: when only the wavelength dimension is present (Angle Mode = Single or Weighted Average), the default is a line chart. When an angle sweep is also active (Angle Mode = Sweep), the chart can be toggled between line and heatmap, and the x-axis can be switched between Wavelength and Angle.

Single-value mode (angle = Single and wavelength = Single or WA): the chart area is hidden and the page switches to table-only mode.

Angular distribution

When Angle Mode is set to Sweep, the chart shows far-field emission intensity (a.u.) vs. angle (deg) for each polarization channel. This view is equivalent to the Angular Spectrum sub-view (the sidebar entry Angular Spectrum is a sub-view within Intensity, not a standalone page).

Polar view: in line-chart mode, enable the Polar Toggle to switch to a polar plot. The polar chart uses 360° mirror symmetry, startAngle = 90, and normalizes the radial axis to the series maximum.

Values: raw far-field intensity, without normalization. To compare shape across angles with normalization applied, use Normalized Angular Distribution.

Normalized views

Normalized Spectrum

Normalization definition: each (angle, polarization) series is scaled so its peak = 1 across wavelengths. TE / TM / Total are normalized independently.

The x-axis is locked to Wavelength (nm); the y-axis is Normalized Intensity. There is no x-axis selector and no chart-type toggle — line chart only.

This view uses the same underlying data as Angular Spectrum, but normalization removes the absolute intensity difference between angles, making it suitable for directly comparing emission spectral shapes across different emission angles.

Normalized Angular Distribution

Normalization definition: each (wavelength, polarization) series is scaled so its peak = 1 across angles. TE / TM / Total are normalized independently.

The x-axis is locked to Angle (deg); the y-axis is Normalized Intensity. Line chart is the default; in line mode the Polar Toggle is available.

This view uses the same underlying data as Angular Spectrum, but normalization removes the absolute intensity difference between wavelengths, making it suitable for comparing the shape of emission lobes across different wavelengths.
