摘要:
A novel single mode optical fiber tapped delay line that uses silicon V‐groove substrates to align an array of directional coupler taps has been demonstrated as a transversal filter. The device was used to generate and correlate 4‐bit, 400‐Mb/s coded sequences. The generated codes exhibited an amplitude uniformity of ±0.04 dB. The electrical correlation output was linear over a range of 25 dB and was limited by electronic components external to the fiber filter itself. Extension of the fabrication technique to include hundreds of taps at intervals as short as several picoseconds may be possible.
