摘要：
We present a design for a temperature insensitive Mach-Zehnder interferometer in which temperaturecompensating 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/degrees K is predicted for 100nm bandwidth around 1550nm.
