Abstract :
This paper reports the first observation of chromatic and intensity optical bistability (OB) in a commercial, active, phosphate glass (Schott IOG-2) microsphere driven by thermal avalanche at room temperature. This is, to the best of our knowledge, the first report of simultaneous intensity OB (at multiple wavelengths) and chromatic OB in a single material.
