Abstract

An all-optical inverter, which operates over a temperature range of -200 to 750 degree(s)C, was demonstrated in erbium- doped borate glass. The dependence of negative nonlinear absorption effect on sample temperature and modulation degree was investigated, using an 810.0 nm laser diode. Reversed-phase waveforms were observed in the transmitted waveform in the temperature range. The glass transition temperature was measured to be 708 degree(s)C by differential thermal analysis. With a decreasing modulation degree, the reversed-phase waveform was obtained. The effect has a characteristic which is almost independent of the sample temperature because it is formed by optical transitions of the inner shell of the erbium ion.
