All-Optical Inverter Operating up to 850°C in an Erbium-Doped Phosphate Glass

The dependence of an all-optical inverter on both sample temperature and modulation frequency was investigated in an erbium-doped phosphate glass using a 809.5 nm laser diode. The reversed-phase waveforms were observed in the transmitted waveform in a temperature range of -220 to 875°C. The glass tr...

Summary:The dependence of an all-optical inverter on both sample temperature and modulation frequency was investigated in an erbium-doped phosphate glass using a 809.5 nm laser diode. The reversed-phase waveforms were observed in the transmitted waveform in a temperature range of -220 to 875°C. The glass transition temperature was measured to be 697°C by differential thermal analysis and the glass was in the form of supercooled liquid between 700 and 930°C. An all-optical inverter which had a negative input-output characteristic was demonstrated in a temperature range of -200 to 850°C.
