Fiber-optic Delay Lines

Optically driven recirculating delay lines, often used in fiber-optic signal processors, convert the source phase noise to spectrally structured intensity noise at the loop output. This spectrum is characterized by deep notches at zero frequency as well as at other multiples of l/(loop delay). An expression is derived for the power spectral density of the output noise. The formulae obtained, ar...

Fiber Optic Delay Line Systems

The 5017 delay lines system, incorporates a high-speed lasers and photodiodes to provide exceptionally high performance. The unit provides high bandwidth and sensitivity to operate with large delays, plus wide dynamic range for operation over a variety of loss budgets.

Rf and Microwave Fiber Optic Delay Line Techniques

Other delay line techniques include energy transfer methods such as crystal or glass substrates that generate acoustic waves. Here, electrical energy is converted to mechanical energy using a transducer. The energy moves through a medium at a speed related to properties of the material used to construct the delay line. Specific geometries of crystal or glass result in longer delays due to inter...
