A thermal compensator, for use in connection with arrayed waveguide grating (AWG) modules which are, in turn, utilized in conjunction with wavelength multiplexing and de-multiplexing within optical networks, is disclosed. The thermal compensator comprises a bow-shaped frame member and a central bar member. The bow-shaped frame member is characterized by a higher coefficient of thermal expansion than that of the central bar member such that the bow-shaped frame member can expand and contract at variable rates compared to that of the central bar member under certain temperature conditions. The bow-shaped frame member is adapted to be attached to a movable section of an athermal arrayed waveguide grating (AAWG) module such that the expansion and contraction movements of the bow-shaped member influence the movement of a movable section of the AAWG module in order to maintain the proper focus of the AAWG module across disparate temperature conditions.
