OPTICAL LIMITER

摘要

An optical power limiter comprises an input optical transmission element, an output optical transmission element, and a power-limiting element disposed between the input and output elements for transmitting optical signals from the inpu t element to the output element. The power-limiting element comprises an optical- limiting solid mixture containing particles of at least one material that produces reversib le thermal changes in response to light above a predetermined optical power level, thereby changing the optical transmission properties of the power-limiting element.< /SDOAB>
