Abstract: A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.

Abstract: Devices and systems which include on-chip waveguides with flattened dispersion are described. In one aspect, silicon nitride slot waveguides that exhibit four zero-dispersion wavelengths with a flattened dispersion over a wavelength range of 500 nm are obtained. The disclosed silicon nitride slot waveguides are used to generate a two-octave supercontinuum from 630 nm to 2650 nm, enabling (a) on-chip generation of 5 fs optical pulses as short as 1.3 cycles, and (b) sensitive single-shot measurements of the absolute carrier-envelope phase using a single integrated waveguide. In another aspect, silicon slot waveguides that exhibits four zero-dispersion wavelengths with a flattened dispersion over a wavelength range of 670-nm are obtained. An octave-spanning supercontinuum is generated in the disclosed silicon slot waveguide, over a wavelength range from 1217 nm to 2451 nm, approximately from bandgap wavelength to half-bandgap wavelength. Input pulses longer that 100 fs can be compressed to 10 fs using the disclosed silicon slot waveguide.
