Abstract
We introduce into optical systems, susceptible to be interrupted or damaged from laser, novel passive solid-state threshold-triggered Wideband Protection Filter (WPF) that blocks the transmission only if the power exceeds a certain threshold. We present new protection capabilities of our latest filter composed of improved technology. The WPF can be readily used for protection of detectors, cameras, or eye safety.
