Strong optical asymmetry of an interference wedge with unequal-reflectivity mirrors and its use in unidirectional
Optics Letters
|October 27, 2009
Abstract:
On the basis of theory and experiment we discuss the strong optical asymmetry in reflection exhibited by an interference wedge when it is constructed of unequal-reflectivity mirrors and show how this feature can be used to develop attractive unidirectional ring lasers. In the proposed ring cavity schemes a single interference wedge is employed simultaneously as a tuning element, as an element introducing asymmetry, and as a laser output coupler.
