Abstract

Integrated-optic, astronomical, two-beam and three-beam, interferometric combiners have been designed and fabricated for operation in the L band (3 microm--4 microm) for the first time. The devices have been realized in titanium-indiffused, x-cut lithium niobate substrates, and on-chip electro-optic fringe scanning has been demonstrated. White light fringes were produced in the laboratory using the two-beam combiner integrated with an on-chip Y-splitter.

摘要

集成光学、天文、双光束和三光束干涉合成器首次被设计并制造出来，用于在L波段（3微米至4微米）运行。这些器件是在钛扩散的x切铌酸锂衬底上实现的，并且已经演示了片上电光条纹扫描。在实验室中，使用与片上Y型分离器集成的双光束合成器产生了白光条纹。
