Microresonator array for wavelength sensing

Abstract

The device described above is easy to manufacture, it is very small, and it is insensitive to vibrations. It has no movable parts and is well suited to determine the wavelength of pulsed signals. The spectral resolution of the array investigated is limited by the uncertainty in the wavelength reading of the laser. The dynamic range can be varied and adjusted to the specific demand by selecting the appropriate resonator sizes. A larger number should also increase the accuracy of the setup.
