16-bit MEMS Latching Type Photonic Time Delay

SKU: METD

The MEMS Series N-bit (up to 16-bit) Photonic Time Delay digitally varies the delay time inside a fiber with an exceptionally large range (maximum delay) and precision (bit). It selectively routes optical signals through N fiber loops whose lengths increase successively by a power of 2. Since each switching element allows the signal to either pass or bypass a fiber loop, a delay T may be inserted, which can take any value (in increments of DT) up to the maximum value T.

This is achieved using a patent-pending MEMS configuration and activated via an electrical control signal. Latching operation preserves the selected optical path after the drive signal has been removed. The unit is a completed module with a built-in driver.
