METHOD OF ANCHORING OPTICAL FIBER IN THE HERMETIC LASER PACKAGE Abstract of the Disclosure An electro-optic package incorporating a semiconductor laser requires a temperature sensor for controlling an electrically operated cooler. An optical fiber end portion is anchored close to the laser to receive light from it. Usually the fiber is anchored by a mass of cured epoxy. This invention proposes using a mass of fusible alloy which is melted and solidified using a cooler in which the polarity of drive current is reversed to convert the cooler into a heater. The temperature sensor is used to maintain the temperature in the package below the alloy melting point while the fiber is positioned. - i -
