Abstract
An optical wave guide coupler with an integral signal modifying element that passively compensates for temperature variations by automatically tilting the element and thereby changing its operating characteristics with changes in temperature. The element is also rotatably, yet firmly, supported by the coupler and is retained at a predetermined angle relative to the axis of the coupler so that the operating characteristics of the element may be selectively varied by rotation of the element holder of the coupler.
