摘要:
An electroabsorption vertical cavity surface emitting laser modulator and/or detector includes a lower reflector, an upper reflector, a middle reflector, a gain region, and an absorber region integrated into a semiconductor die. The middle reflector is disposed between the lower and upper reflectors. Together, the lower and middle reflectors define a first resonant cavity within the semiconductor die, while the upper and middle reflectors define a second resonant cavity within the semiconductor die. The first and second resonant cavities are optically coupled. The gain region is disposed within the first resonant cavity and is capable of generating an optical carrier wave. The absorber region is disposed within the second resonant cavity and is capable of modulating a signal on the optical carrier wave when subjected to a signal voltage.

The present invention provides a mechanism for adjusting the activity of an integrated digital circuit such as a processor to reduce voltage changes attributable to current changes triggered by clock gating. The processor includes one or more functional units and a current control circuit that monitors activity states of the processor's functional units to estimate the current consumed over n clock cycles. The current control circuit estimates the current change for a given clock cycle from the n activity states and compares the estimated current change with first and second thresholds. The processors activity is decreased if the estimated current change is greater than the first threshold, and the processor activity is decreased if the estimated current change is less than the second threshold.

Embodiments herein relate to a system, apparatus, and/or process for producing a spin orbit torque (SOT) electrode (102) that includes a first layer (102a) with a first side to couple with a free layer (110) of a magnetic tunnel junction (MTJ) (108) and a second layer (102b) coupled with a second side of the first layer opposite the first side, where a value of an electrical resistance in the first SOT layer is lower than a value of an electrical resistance in the second SOT layer and where a current applied to the SOT electrode is to cause current to preferentially flow in the first SOT layer to cause a magnetic polarization of the free layer to change directions. During production of the SOT electrode, the second layer may act as an etch stop.
