Cavity.Calc( gain=True ) - calculate gain required for lasing #77

Open demisjohn opened 8 years ago

This would sweep the gain of the Active region, and find where the imaginary part of the guided mode = 0 (or eigenvalue = 1).

May require additional Materials parameter:

myMat = pf.Material( 3.45, active=True )

So Cavity.calc knows which layer's imaginary part to sweep. It's possible this could also be determined by just looking at the Eigenvalue's real part without sweeping it.

Losses are now calc'd in ea21b87d69224e19f5fae747812837b80859fc34.

Instead of sweeping gain, just calc losses, and user can plot the lowest-loss mode?
