Abstract
The present invention is directed to a process and product of a process in the field of optical directional coupler switches. The application of laser light to the input ports of a coupler switch at a power level approximately twice or greater the operational power level that has been discovered to cause optical damage produces a remedial effect of stabilizing the switching characteristics of the optical coupler switch. The resulting optical coupler switch has improved transmission characteristics when measured by a transfer function over that of an untreated coupler switch.
