Solid State Variable PM Photonic Time Delay
The SSTD PM Series Photonic Time Delay selectively routes optical signals
through N fiber segments whose lengths increase successively by a power
of 2. Since each switching element allows the signal to either connect or
bypass a fiber segment, a delay T may be inserted, which can take any
value (in increments of ∆T) up to the maximum value T. This is achieved
using a patent pending non-mechanical configuration and activated via an
electrical control signal. Latching operation preserves the selected
optical path after the drive signal has been removed. The solid-state
configuration 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.
