Variable Ultra-Short Optical Time Delay Line
0 to 22ps range with 4 bit resolutionThe SSTD Series Photonic Time Delay selectively routes optic signal through N delay segments whose delay time increase successively by a power of 2. Since each switching element allows the signal to either connect or bypass a delay segment, a delay T may be inserted that can take any value, in increments of DT, up to the maximum value T. This is achieved using patent pending non-mechanical configurations and activated via an electrical control signal. Latching operation preserves the selected optical path after the drive signal has been removed. All solid-state configurations eliminates the need for mechanical movement and organic materials. The device is designed to meet the most demanding switching requirements of ultra-high reliability and fast response time.
