ABSTRACT:
Particular embodiments of the present invention relate generally to connecting structures comprising heated flexures for aligning a first component with a second component. According to one embodiment of the present invention, an optical package includes a laser, a wavelength conversion device, a mirror and a connecting structure. The mirror reflects a laser beam such that the laser beam is incident upon the wavelength conversion device. The connecting structure includes a structure base and three bipod flexures. Each of the bipod flexures includes first and second bipod legs extending from the structure base to the mirror. A heating element is thermally coupled to the first and second bipod legs. The bipod flexures are arranged in a tripod configuration such that changes in the length of the bipod legs alter the reflection of the laser beam from the mirror.
