Abstract
A power efficient assembly is provided for applying a temperature gradient to a Fiber Bragg grating. The assembly includes inner and outer enclosures, the outer enclosure defining an insulation chamber around the inner enclosure. The respective ends of the inner and outer enclosures are in thermal contact. A heat exchange system, such as coiled resistive wires or thermo-electric coolers, applies different temperatures to the opposite ends of the outer enclosure.
