In this work the fabrication and characterization of As₂S₃ and erbium-doped As₂S₃ layers on Er:Ti:LiNbO₃ channel waveguide amplifiers are reported and compared with Er:Ti:LiNbO₃ channel amplifier for the first time to the author’s knowledge. We have first characterized a typical Er:Ti:LiNbO₃ waveguide amplifier of 2.6 cm length and measured a small signal net gain of 2.5 dB for TM mode under 1470 nm pumping. Further optical characterization of Er:Ti:LiNbO₃ case was also performed for two wavelengths of 1531 and 1550 nm in an Er:Ti:LiNbO₃ case of 3.5 cm length. Signal enhancement of 22.234 and 6.463 dB was obtained for two wavelengths respectively and showed a stability behavior for an incident pump power of about 144 mW. As₂S₃ layer and erbium doped As₂S₃ waveguide layer were deposited by thermal and co-sputtering respectively on two Er:Ti:LiNbO₃ channel waveguide amplifiers as hybrid waveguide amplifiers then absorption and amplification were characterized. Whilst net gain was not improved due to the presence of pump-induced up-converted green light and moisture diffused in overlay waveguides, this nonetheless represents a further step towards the realization of hybrid waveguide amplifiers with loss compensation in nonlinear photonics.

在这项工作中，报道了Er：Ti：LiNbO ₃通道波导放大器上的As ₂ S ₃和掺砷的As ₂ S ₃层的制造和表征，并首次将其与Er：Ti：LiNbO ₃通道放大器进行了比较。作者的知识。我们首先对典型的2.6 cm长的Er：Ti：LiNbO ₃波导放大器进行了表征，并在1470 nm泵浦下对TM模式测量了2.5 dB的小信号净增益。还对Er：Ti：LiNbO ₃中的两个波长分别为1531和1550 nm的Er：Ti：LiNbO ₃进行了进一步的光学表征长度为3.5厘米的情况。分别针对两个波长获得了22.234 dB和6.463 dB的信号增强，并显示了约144 mW的入射泵浦功率的稳定性。作为₂ š ₃层和铒掺杂为₂ š ₃波导层被沉积的热和共溅射分别在两个二：钛：铌酸锂_3个通道波导放大器作为混合波导放大器然后吸收和扩增进行了表征。尽管由于泵浦感应的上转换绿光和湿气在覆盖波导中扩散而没有改善净增益，但这仍然是朝着在非线性光子学中实现损耗补偿的混合波导放大器迈进的又一步。
