Local temperature control of photonic crystal devices via micron-scale electrical heaters

Posted by Caltech

Kavli Affiliate: Andrei Faraon | First 5 Authors: Andrei Faraon, Jelena Vuckovic, , , | Summary: We demonstrate a method to locally control the temperature of photonic crystal devices via micron-scale electrical heaters. The method is used to control the resonant frequency of InAs quantum dots strongly coupled to GaAs photonic crystal resonators. This technique […]

Effect of resistance feedback on spin torque-induced switching of nanomagnets

Posted by Chicago

Kavli Affiliate: Thomas M. Crawford | First 5 Authors: Samir Garzon, Richard A. Webb, Mark Covington, Shehzaad Kaka, Thomas M. Crawford | Summary: In large magnetoresistance devices spin torque-induced changes in resistance can produce GHz current and voltage oscillations which can affect magnetization reversal. In addition, capacitive shunting in large resistance devices can further reduce […]
