Abstract
A single‐mode optical fiber tapped delay line which utilizes microbend taps has been constructed. The taps are obtained simply and repeatably and are uniform to ±1 dB. A device with 19 taps and a 1‐ns delay between taps was constructed. The average tap strength was 1.5%. The frequency response for the device has been measured and simple programmability has also been demonstrated. Extension of the procedure to devices with 102–103 taps and 100‐ps time delays is possible.Keywords
