Abstract:
An in-line spectrometer/polarimeter device, the device comprising:an optical waveguide; wavelength manipulating optics capable of manipulating one or more wavelengths, the wavelength manipulating optics comprising one or more wavelength dispersive elements in the optical waveguide; and polarization manipulating optics capable of manipulating the polarization of the one or more wavelengths, wherein the one or more wavelength dispersive elements tap from the waveguide at least a portion of light propagating through the waveguide, such that the tapped light is directed to or through at least a portion of the polarization manipulating optics, wherein one or more of the wavelength dispersive elements optionally functions as a portion of the polarization manipulating optics, and wherein the device provides for monitoring of the one or more wavelengths present in the light propagating through the waveguide and for monitoring of the polarization characteristics of each of the one or more channels.
