摘要： Systems and methods for converting wideband signals in the optical domain are provided. A device for obtaining a digital representation of a received signal may include a spatially dispersive element that may be configured to spatially disperse frequencies in an optical-domain representation of the received signal; a spatial light modulator that may be configured to mix the dispersed optical frequencies by imposing a mixing matrix on an optical intensity of the dispersed optical frequencies; an optical sensor that may be configured to obtain an electrical representation of the mixed dispersed optical frequencies; and a signal recovery processor that may be configured to obtain a digital representation of the received signal based on the electrical representation and the mixing matrix. The signal recovery processor may be further configured to determine a modulation format of the digital representation and may demodulate the digital representation based on the modulation format.

摘要： A planar spectrograph for demultiplexing optical wavelength signals includes a monolithic substrate. The substrate has a diffraction grating etched therein. The diffraction grating is integrally formed in the substrate to be in operative relationship with input light to diffract and reflect the input light to a detector. A recess is formed in the substrate to accommodate a separate slab waveguide. A slab waveguide is dimensioned and configured to fit within the recess, and the waveguide guides input light to and from the diffraction grating. A silicon-on-insulator spectrographs is also described, as well as, fabrication processes for manufacturing these spectrographs.

摘要： Various embodiments are directed to a photonic impulse generator comprising a periodically chirped photonic source a single-frequency photonic source, a photodetector, an optical coupler, and a filter. The optical coupler may be positioned to couple an output of the single-frequency photonic source to an output of the periodically chirped photonic source, resulting in a combined photonic signal. The photodetector may be positioned to receive the combined photonic signal and generate a combined electrical signal. The filter may be in electrical communication with an output of the photodetector to receive the combined electrical signal.
