Variable Optical Attenuator with Integrated Control Based on Strongly Correlated Materials

IntroductionAccurate optical attenuation in optical network systems and optical devices is currently achieved through the use of expensive, complex and bulky external sensors in combination with a linear controller. Description of TechnologyThis technology is a variable optical attenuator that attenuates infrared wavelengths. This attenuator does not...

Voltage-controlled Resistor Device Based on Phase Transition Materials

IntroductionCircuit designers often require a resistor that consistently alters its resistance based upon an input control voltage. A voltage-controlled resistor (VCR) is a three-terminal device that varies the resistance between two terminals relative to voltage in the third terminal. VCRs are commonly used in the following electronics: variable gain...
