Abstract
An optical system includes an assembly comprising mechanical mount, a heating element coupled to the mechanical mount, and a base plate coupled to the heating element. The base plate comprises a longitudinal groove. The optical assembly also includes a fiber including a fiber Bragg grating (FBG) passing through the assembly. The fiber is disposed in the longitudinal groove of the base plate and is configured to move freely in a longitudinal direction and the FBG of the fiber is disposed in the longitudinal groove of the base plate. The optical assembly further includes a first attachment element mechanically coupled to a first end of the fiber and a second attachment element mechanically coupled to a second end of the fiber.
