Estimating the term…
A known electro-optic has a semiconductor laser, a temperature sensor for controlling an electrically operated cooler, and an optical fiber end portion anchored close to the laser to receive light from it. Usually the fiber is anchored by a mass of cured epoxy. This invention proposes anchoring the fiber in a mass of fusible alloy which is melted and solidified using a Peltier effect device which is driven with one polarity current to function as a heater and with a reverse polarity current to function as a cooler. Once the package is complete and the laser is operating, the temperature sensor together with the Peltier effect device functioning as a cooler are used to cool the laser.
An electro-optic package comprising:
A method of operating a thermoelectric device functioning as a heater when a voltage of a first polarity is applied thereto and functioning as a cooler when a voltage of reverse polarity is applied thereto, said thermoelectric device housed within an electro-optic package which also houses a light emitting device, the light emitting device being mounted in thermally conducting relationship to the thermoelectric device, the method comprising:
