This article discusses a new invention by NIST related to superconducting opto-electronic transmitter circuits. These circuits allow superconducting elements to drive light sources more effectively by generating an amplified current or voltage pulse when the superconducting element is driven above a certain threshold. After generating light, the circuit resets to its resting state, preventing issues like latching that occur in previous designs. This improvement allows for better control and reliability in opto-electronic systems.
The new circuits are particularly useful for highly spatially multiplexed communication systems and could be integrated with AI hardware. The article also notes that CMOS technology has an advantage in this area due to the availability of accurate models and modeling techniques. This development represents progress in combining superconducting electronics with optoelectronics, potentially leading to more efficient and powerful communication technologies.
