Fiber-Optic Pulse Delay Using Composite Zone Plates for Very Fast Optoelectronics : Waves, Optics and Quantum Electronics

Optical pulse delay technique is important in such fields as time-resolved spectroscopy, optical sampling and very high speed time division multiplexing of digital data. This paper reports a proposal to assemble an optical pulse delay unit with a reduced number of components by using a composite zone plate and its successful implementation with a dynamic range of 300 ps delay of 40 ps diode laser pulses.
