Abstract

We review an on-chip approach for spontaneous Raman spectroscopy and
surface-enhanced Raman spectroscopy based on evanescent excitation of the
analyte aswell as evanescent collection of the Raman signal using complementary
metal oxide semiconductor compatible single mode waveguides. The
signal is either directly collected from the analyte molecules or via plasmonic
nanoantennas integrated on top of thewaveguides. Flexibility in the design of
the geometry of thewaveguide, and/or the geometry of the antennas, enables
optimization of the collection efficiency. Furthermore, the sensor can be integrated
with additional functionality (sources, detectors, spectrometers) on
the same chip. In this paper, the basic theoretical concepts are introduced to
identify the key design parameters and some proof-of-concept experimental
results are reviewed.
