摘要： The present invention generally relates to the operation of optical network equipment such as optical amplifiers. In one aspect, a method of operating an optical amplifier is provided such that output of the optical amplifier avoids the effects of operating an optical gain medium in a non-linear (kink) region of an L-I curve. The method generally includes operating an optical gain medium in a fully off state or fully on state above the kink region with a PWM signal. In another aspect, the effects of the kink region may be compensated for by utilizing a lookup table. A sample of the optical power of an amplified optical signal may be used to select an entry in the lookup table that compensates for non-linearities in the kink region. In yet a further aspect, a lookup table may be used to control a pulse modulator to compensate for non-linearites in the kink region of the L-I curve.

摘要： The present invention generally relates to dynamic thermal management of a device. In one aspect, a method for thermally controlling a device is provided. The method includes setting a value of a set point in a thermoelectric cooler, wherein the set point corresponds to a first operating state. The method also includes monitoring a condition of the device to determine if the device is in the first operating state or a second operating state. Additionally, the method includes dynamically altering the value of the set point according to an algorithm upon determination that the device is in the second operating state. In another aspect, a method for dynamically controlling a device having a thermoelectric cooler is provided. In yet a further aspect, a system for dynamic thermal management of a device is provided.
