    Abstract: An apparatus for performing Raman spectral analysis of a sample is described, comprising a coherent light source, an first optical chain to direct the coherent light to impinge on the sample, a second optical chain to direct the scattered light onto a diffraction grating, and a third optical chain to direct the diffracted light onto detection array. The diffraction grating is a stairstep with a metalized surface, and a plurality of metalized stripes on a flat surface is disposed in a direction orthogonal to the long dimension of the stairsteps. The region between the flat surface and the stairstep is transparent. The zeroth-order fringe is selected by a slit and directed onto camera. The resultant interferogram is Fourier transformed to produce a representation of the Raman spectrum.

    Abstract: Disclosed is an interferometer comprising a light source, a reflective element, and a photodetector. The light source is configured to emit a light beam, and an angle is formed by inclusion between a direction to which the light beam travels and the reflective element, the photodetector is configured to be substantially perpendicular to the reflective element. The light beam is halved into a first light beam propagating by the included angle, and a second light beam reflected off the reflective element, the first light beam and the second light beam interfere each other to form an interferogram on the photodetector, which detects the interferogram. By benefit of above, the interferometer does not need to reposition its parts in order to make adjustment to interferogram, thereby simplifying optical element setup and minimizing physical volume of the interferomger. Also disclosed is a spectrometer including the same interferometer and a Fourier-transform-capable analyzer.

    Abstract: A transform spectrometer measurement apparatus and method for a planar waveguide circuit (PLC). The spectrometer typically includes an input optical signal waveguide carrying an input optical signal; a plurality of couplers, each connected to the input optical signal waveguide, and each including a coupler output for carrying a coupled optical signal related to the input optical signal; and an array of interleaved, waveguide Mach-Zehnder interferometers (MZI), each having at least one input MZI waveguide, each MZI input waveguide receiving a coupled optical signal from a respective coupler output. A phase shifting circuit is applied to at least one arm of the MZIs to induce an active phase shift on the arm to thereby measure phase error in the MZIs. Light output from the MZIs is measured under intrinsic phase error conditions and after an active phase shift by the phase shifting circuit.
