Agiltron Optical Time Delays

Integrated Solid State Variable Photonic Time Delay

The 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 ∆T, 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.

MEMS Variable Photonic Time Delay

The MEMS Series Photonic Time Delay digitally varies the delay time inside a fibre with exceptionally large range (maximum delay) and precision (bit). It selectively routes optical signals through N fibre loops whose lengths increase successively by a power of 2. Since each switching element allows the signal to either pass or bypass a fibre loop, 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 MEMS configuration and activated via an electrical control signal. Latching operation preserves the selected optical path after the drive signal has been removed. The device is designed to meet the most demanding switching requirements of ultra-high reliability, vibration insensitivity, and low power consumption. It is a completed module with built-in driver.

Motorised Variable Optical Time Delay

The Motor Driven Variable Optical Time Delay features fast speed and high accuracy. It consists two collimators and a movable reflector controlled by a precision step motor. Light from an input fibre collimator projects into free space and is collected by an output fibre collimator. The distance the light travels in free space is varied by the movable reflector. The device is conveniently controlled by a computer via a USB cable interface. A graphic control software is provided.

N Bit Lossless Variable Photonic Time Delay Module

This N-bit (N ≥ 10) Photonic Time Delay Module selectively routes optical signals through N fibre segments with the different lengths. Each fibre segment is defined to have the delay as

ΔT_i = 2^(i-1)ẟT , i = 1,2,...N

Where ẟT is the increment of time delay.
Therefore, the module provides N-bit of digitally variable time delay, having the total time delay as

ΔT_Total = (2^N - 1) ẟT

N and ẟT can be defined by customer.

The EDFAs is used in the module to compensate the optical loss through optic fibre segments and switches. The optical loss between the optic fibre segment and the bypassing path is balanced internally to get the excellent uniformity of optical power between different time delays in long time delay ranges.

NanoSpeed Single Mode Variable Photonic Time Delay

The NSTD Series Photonic Time Delay generates variable time delay by selectively routing optical signals through N (<=8) fibre segments whose lengths increase successively by a power of 2 to form a N bit digital delay line. The NSTD allows customers to splice each fibre loop, creating increments of DT, up to the maximum value T. The switching between each loop is achieved using a patented non-mechanical configuration. 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.
