Description: This object specifies the current min propagation time difference between eigenmodes X and Y for the interface in 1/100 ps.

What is coiOptCurrentDifferentialGroupDelayMin?

Reports the lowest (minimum) differential group delay -- the propagation time difference between the X and Y polarization eigenmodes -- for the interface during the current interval, in hundredths of a picosecond.

Examples
