v_g_from_n_g(→ float)

Calculate the Group Velocity (v₉) from the Group Index (n_g).

n_g_from_v_g(→ float)

Calculate the Group Index (n_g) from the Group Velocity (v₉).

v_g_from_n_g(n_g: float) → float[source]#

Calculate the Group Velocity (v₉) from the Group Index (n_g).

The relationship between group velocity and group index is given by the equation:

[ v_g =

rac{c}{n_g}

]

where:

  • ( v_g ) is the group velocity (m/s),

  • ( n_g ) is the group index (dimensionless),

  • ( c ) is the speed of light in vacuum (m/s).

Parameters:
n_g (float):

The group index, representing the factor by which the group velocity is reduced relative to the speed of light in vacuum.

Returns:
float:

The calculated group velocity in meters per second (m/s).

n_g_from_v_g(v_g: float) → float[source]#

Calculate the Group Index (n_g) from the Group Velocity (v₉).

The relationship between group velocity and group index is given by the equation:

[ n_g =

rac{c}{v_g}

]

where:

  • ( n_g ) is the group index (dimensionless),

  • ( v_g ) is the group velocity (m/s),

  • ( c ) is the speed of light in vacuum (m/s).

Parameters:
v_g (float):

The group velocity in meters per second (m/s).

Returns:
float:

The calculated group index (dimensionless).
