Yes. For instance, by using CFBG. You can google paper below:

Hope this help.

The simplest way is a setup sometimes called "an optical trombone." It's illustrated in the attached image.

Basically the bottom two mirrors are mounted on a translation stage. As the stage is displaced by x, total pathlength added to the beam is 2x.

it is not possible to realize the tunable delay line component in simulation. instead of this  you can directly use delay line or time delay component with sweep values.
