# EffectiveIndex2D.Mode Class

class EffectiveIndex2D.Mode

  Detailed information about the mode.

## Attributes

`loss` | Mode losses (1/cm).
`neff` | Mode effective index.
`power` | Total power emitted into the mode (mW).
`symmetry` | Mode symmetry ('positive', 'negative', or None).
`total_absorption` | Cumulated absorption for the mode (mW).

## Descriptions

### Attribute Details

EffectiveIndex2D.Mode.loss = <property object>

  Mode losses (1/cm).

EffectiveIndex2D.Mode.neff = <property object>

  Mode effective index.

EffectiveIndex2D.Mode.power = <property object>

  Total power emitted into the mode (mW).

EffectiveIndex2D.Mode.symmetry = <property object>

  Mode symmetry (‘positive’, ‘negative’, or None).

EffectiveIndex2D.Mode.total_absorption = <property object>

  Cumulated absorption for the mode (mW).

  This property combines gain in active region and absorption in the whole structure.
