用于飞秒laser写入光子集成电路的热移相器
Thermal phase shifters for femtosecond laser written photonic integrated circuits
摘要：
光子集成电路（PIC）是当今公认的一种有效的解决方案，以满足许多实际应用中的经典和量子光学的苛刻要求。集成在光子电路中的移相器提供了动态重新配置其属性的可能性，以便微调其操作或产生自适应电路，从而大大扩展了这些器件的质量和适用性。在本文中，我们提供了一个彻底的讨论，一个可以遇到的主要问题时，使用热移位器重新配置光子电路。然后，我们将展示如何通过仔细设计热移位器并选择最合适的方式来驱动它们来解决所有这些问题。这种性能的改善是通过在飞秒激光写入PIC（FLW-PIC）中制造热移相器，并详细描述其操作来证明的。在功耗、小型化和稳定性方面取得了前所未有的成果，使可重构FLW-PIC的可扩展实施成为可能，这些可重构FLW-PIC可以在应用中轻松校准和开发。
英文摘要：
Photonic integrated circuits (PICs) are today acknowledged as an effective solution to fulfill the demanding requirements of many practical applications in both classical and quantum optics. Phase shifters integrated in the photonic circuit offer the possibility to dynamically reconfigure its properties in order to fine tune its operation or to produce adaptive circuits, thus greatly extending the quality and the applicability of these devices. In this paper, we provide a thorough discussion of the main problems that one can encounter when using thermal shifters to reconfigure photonic circuits. We then show how all these issues can be solved by a careful design of the thermal shifters and by choosing the most appropriate way to drive them. Such performance improvement is demonstrated by manufacturing thermal phase shifters in femtosecond laser written PICs (FLW-PICs), and by characterizing their operation in detail. The unprecedented results in terms of power dissipation, miniaturization and stability, enable the scalable implementation of reconfigurable FLW-PICs that can be easily calibrated and exploited in the applications.
