Latest Patents
One of Derbyshire's key patents is titled "Retrofit heater for erbium fiber in an erbium-doped fiber amplifier." This invention describes a heater system designed to maintain optimal temperatures in an erbium-doped fiber amplifier (EDFA). The system includes a pump laser that provides optical power to the erbium fiber, which is crucial for the operation of fiber optic communication systems. The pump laser is equipped with a thermoelectric cooler (TEC) that activates when a predetermined maximum temperature is reached, ensuring the laser operates below this threshold. A temperature sensor monitors the laser's temperature and communicates with a control circuit to generate necessary control signals. The heater unit, thermally connected to the erbium fiber, is activated when the sensed temperature falls below a predetermined minimum value, thus maintaining the fiber's temperature above this critical level. A switch facilitates the automatic direction of current to either the heater or the TEC based on the temperature readings.
