    FIGURE 1. The SWIFTS principle is compared with grating spectrometers and Michelson (Fourier-transform) spectrometers. (a) A Fourier-transform spectrometer is shown in a Michelson configuration. (b) A SWIFTS spectrometer is like a simplified Michelson interferometer in which the scanning mirror and the detector are replaced by the nanodetectors. (c) A grating spectrometer is an interferometric system that creates an optical path difference (OPD) equal to L x (sinα+sinβ) between the rays reaching the two sides of the grating. For a given grating width L, the resolving power of the grating is maximum for two angles that correspond to the SWIFTS configuration (incident and diffracted light are aligned).
    SWIFTS is a new principle of spectroscopy that can be implemented in an integrated chip, delivering picometer resolution over a spectral range of several hundred nanometers.
    Resolution Spectra Systems ZOOM Spectra spectrometer
    The ZOOM Spectra spectrometer can be used over the entire 630–1070 nm range without hardware modifications.
    A SWIFTS spectrometer characterizes an 852 nm DFB laser at its nominal operating temperature of 15º to 40ºC between 851.200 and 853.180 nm, showing its characteristic singlemode profile. Further analysis at a 100 Hz measurement rate at the out-of-recommended temperature range of 5º to 15ºC shows dual-mode behavior, while measurements at a higher rate of >1000 kHz show that neither mode exists at the same time, indicating mode-hopping behavior for the laser.
    In many spectrometer designs, there is often a tradeoff between miniaturization and high performance.
