Resolving power of gratings in planar multimode waveguides

Contributed Papers


A multimode planar grating spectrograph focuses, into the same point, all modes with equal propagation constants. Guided waves with equal propagation constants may have different free-space wavelengths within a bandwidth determined by the numerical aperture of this structure. The consequences for the spectral resolution of a multimode planar grating are quantitatively discussed.
