Abstract
We propose a rotatory-dispersion based wavemeter, aiming to reduce the cost and complexity, and retain sufficient measurement accuracy. We have built the wavemeter in-house around very low-cost components, and the no-scanning nature leads to a compact and robust instrument. We give a description of the construction and operating principle, and provide experimental proof in two communication interesting windows. Testing experiments indicate that an absolute measurement accuracy of ±6 pm is believed to be achievable. Besides, this design allows a customizable operating waveband over visible
and most of the near-infrared spectrum..
