ABSTRACT
We have developed a super compact optical
fluorescence spectrometer. Our innovative design combines
advantages of guided wave planar optics and free-space
microoptics. This innovation allows for miniaturization that
is not achievable with pure planar or pure free-space optics.
A prototype device has volume of its optical part below
1cm3
. The spectrometer covers 450nm-650nm spectral
range, and provides spectral resolution of 0.5nm. Next
generation prototype, currently under development, will
have volume below 10mm3
, cover the entire visible range
from 400-700nm, provide spectral resolution of at least
2nm, and work simultaneously with up to 35 independent
optical inputs. The key component of the micro-
