Salvador Poveda-Hospital, Nicolás Quesada, Yves-Alain Peter

AI总结:

该研究系统表征PIN-PMN-PT晶体的湿法、反应离子和离子束刻蚀特性,并据此制备薄膜、单模脊形波导及集成电光相位调制器,获得19.2 V·cm的$V_πL$。

摘要:

我们研究了PIN-PMN-PT晶体的刻蚀特性,探索了多种湿法刻蚀溶液、反应离子刻蚀气体以及离子束刻蚀。系统测量了每种方法的刻蚀速率和表面粗糙度。描述并实施了一种用于获得PIN-PMN-PT薄膜的工艺流程,以便后续构建单模脊形波导。通过在波导两侧沉积电极,制备了一种集成电光相位调制器。我们的相位调制器所涉及的电光系数为$r_{51}/r_{42}$。对性能进行了测试,实现了19.2 V·cm的$V_πL$。

英文摘要:

We investigate the etching characteristics of PIN-PMN-PT crystals, exploring various wet etching solutions, reactive ion etching gases, and ion beam etching. The etch rate and surface roughness are systematically measured for each method. A process flow to obtain PIN-PMN-PT thin films is described and performed to later build a single mode rib waveguide. An integrated electro-optic phase modulator is fabricated by depositing electrodes on the sides of the waveguides. The electro-optic coefficient implied in our phase modulators is the $r_{51}/r_{42}$. The performances are tested achieving a $V_πL$ of 19.2 V$\cdot$cm.
