Optical radiation from coated microsphere with active core
GN Burlak - Physics Letters A, 2002 - Elsevier
We studied numerically the regimes of optical radiation from a coated microsphere with
active core. We found that the reflection coefficient can exceed unit in the band of gain. The
Q factor of eigenfrequencies inside of gain area becomes negative when number of layers in
the stack is large enough.
