"The organic material used in this study, Lightwave Logic’s Perkinamine chromophore37, has also been investigated for its stability and over-time degradation. A recent study shows that the electro-optic materials offer a high glass-transition temperature (>170?°C) and a decomposition temperature of >225?°C (ref. 44). These temperatures are far above the device’s operating temperatures and enable constant performance over a long time. The material has been tested for reliability in modulators for >5,000?h at 85?°C (ref. 44). In addition to these data, in this work, we demonstrate high-temperature operation for 330?min at a device temperature of 85?°C with RT 1 to observe any burn-in effects of the organic electro-optic material. Performance degradation of organic electro-optic materials at higher temperatures is typically observed to be the strongest at the beginning of temperature exposure and saturates over time45,46. With the 330?min operation test, we take a sample of the most critical period of high-temperature operation lifetime of organic electro-optic modulators. The device was operated with a 100?GBd NRZ signal source and was tested for the transmitted eye quality (Extended Data Fig. 6a). Within the first 60?min, the expected burn-in is observed (Extended Data Fig. 6b). Afterwards, the transmitted eye quality stabilized at around a bit error rate (BER) of 10–5. Even though the chip temperature fluctuated slightly and the laser wavelength is constant, clear and open eye diagrams were observed during the whole measurement time "
