Abstract

The present invention provides a temperature-insensitive Mach-Zehnder interferometer, including: a first mode converter; a second mode converter, located on one side of the first mode converter and with a distance from the first mode converter; and a connecting arm, located between the first mode converter and the second mode converter, one end of the connecting arm is connected with the first mode converter, and the other end is connected with the second mode converter. The connecting arm includes a straight waveguide connecting arm. The temperature-insensitive Mach-Zehnder interferometer of the present invention can be configured to be insensitive to temperature by adjusting parameters such as the width and thickness of the connecting arm.
