Abstract

We introduce a novel Cr:YAG waveguide, fabricated using the sol-gel technique, as a potential game-changer in high-speed optical communication. This waveguide, a strong candidate for a broadband fiber amplifier covering the interval from 1.3 μm to 1.6 μm, is fabricated on a coat-etched microchannel quartz substrate. The waveguide's fluorescence spectrum is centered at 1550 nm, boasting a gain measurement of 1.2 dB. These waveguide chips, with their exciting potential for integration into silicon photonic chips, are positioned to bring about significant advancements in high-speed optical communication applications.

摘要

我们介绍了一种采用溶胶-凝胶技术制造的新型Cr:YAG波导，它有望成为高速光通信领域的变革者。这种波导是覆盖1.3μm至1.6μm波长范围的宽带光纤放大器的有力候选者，它被制造在涂层蚀刻微通道石英衬底上。该波导的荧光光谱中心位于1550nm，增益测量值为1.2dB。这些波导芯片具有集成到硅光子芯片中的巨大潜力，有望在高速光通信应用中带来重大进展。
