摘要

我们提出了一种温度不敏感马赫-曾德尔干涉仪的设计，其中温度补偿部分是通过定制的亚波长光栅实现的。通过设计热响应和该段的相对长度，预测在1550nm左右的100nm带宽下，总体温度不灵敏度低于±4pm/°K。

Temperature Insensitive Waveguide Interferometer based on Subwavelength Gratings

We present a design for a temperature insensitive Mach-Zehnder interferometer in which temperature-compensating segment is achieved through tailored subwavelength gratings. By engineering the thermal response and the relative length of this segment, an overall temperature insensitivity below ±4pm/°K is predicted for 100nm bandwidth around 1550nm.
