Claim:
1. A resonator-enhanced Raman spectrometer, comprising: at least one laser light source, wherein said at least one laser light source is a tunable pump laser source and configured to generate a light with a frequency and a polarization state; a polarization controller in series with each of said at least one laser light source; at least one of an optical waveguide and free-space optics in series with each of said polarization controller for delivery of optical excitation sources; at least one resonator coupled to said optical excitation sources, wherein said at least one resonator has a resonant mode; a photodetector operably connected to said at least one resonator; a spectragraph for analysis of information from said at least one resonator; and an imaging device in cooperation with said spectragraph, wherein the tunable pump laser source and the polarization controller are configured to selectively excite a resonant transverse magnetic mode or a resonant transverse electric mode of said at least one resonator.
