摘要： A serpentine integrated grating spectrometer includes a serpentine delay line and a plurality of grating couplers. The serpentine delay line includes a plurality of parallel waveguide segments that are coplanar in a delay-line plane. The serpentine delay line serially connects each of the plurality of grating couplers. Each of the plurality of grating couplers (i) is located at a respective one of the plurality of parallel waveguide segments, and (ii) direct light propagating in the serpentine delay line out of the delay-line plane. The plurality of waveguide segments is M in number and impart a total group delay time ry on light propagating therethrough. Each of the plurality of grating couplers impart a grating coupler delay tx on light propagating therethrough that exceeds (ty/M), the time delay for a single segment of the M parallel segments.
