Response Time

Definition

Response time refers to the duration it takes for a system, such as an optical detector or an optical logic gate, to react to an input signal and produce an output. This is a crucial metric in evaluating the performance of optical systems, as it directly impacts the speed at which information can be processed and transmitted. Faster response times generally lead to more efficient data handling and improved overall system performance.
