Integrated standing-wave transform spectrometer for near infrared optical analysis

We have presented an integrated standing-wave spectrometer operating in the near a mirror flexure uniformity allows for increased mirror scan length without tip-tilt problems, which improves spectral resolution. The GaAs detector provides excellent near IR responsivity. The integrated design allows the mirror to move within a few gm of the detector. The simple operation of this compact device, with a low power continuous-scan mirror, permanent alignment, and only three contacts, should enable implementation in a wide variety of miniaturized sensing systems.
