Example 6. Increase a source’s wavelength accuracy

This example program uses the Agilent 86120C to increase the abso- lute wavelength accuracy of Agilent 8167A, 8168B, and 8168C Tunable Laser Sources. Essentially, the Agilent 86120C’s accuracy is transferred to the tunable laser source. The absolute accuracy of the tunable laser source is increased from <±0.1 nm to <±0.003 nm which is the Agilent 86120C’s absolute accuracy (at 1550 nm).

In order to run this program, the tunable laser source’s firmware must support the automatic alignment command, WAVEACT.

The program uses the following measurement algorithm:

Identify and initialize the Agilent 86120C and tunable laser source Ask user for desired wavelength

Set wavelength of tunable laser source Turn tunable laser source’s output on Enter loop

Measure wavelength

Compare wavelength to desired wavelength

Realign tunable laser source’s wavelength

Check if wavelength changed from last pass

Repeat until (delta wavelength < 0.0015 nm or wavelength is stable)
