Abstract
A spectrometer on a chip system includes a plasmonic chip configured to have first plural grooves and second plural grooves, formed at a non-zero angle relative to the first plural grooves, wherein the first and second plural grooves generate plasmon resonance patterns when illuminated with an incident light beam, a light detector configured to receive a transmitted light beam or a reflected light beam, and to transform the transmitted light beam or the reflected light beam into an electronic reflected image, RI, and a processor that hosts a deep learning application configured to receive the electronic reflected image RI and generate a spectrum of the reflected light.
Claims20
A spectrometer on a chip system comprising:
- a plasmonic chip configured to have first plural grooves and second plural grooves, formed at a non-zero angle relative to the first plural grooves, wherein the first and second plural grooves generate plasmon resonance patterns when illuminated with an incident light beam;
- a light detector configured to receive a transmitted light beam or a reflected light beam, and to transform the transmitted light beam or the reflected light beam into an electronic reflected image, RI;
- and
- a processor that hosts a deep learning application configured to receive the electronic reflected image RI and generate a spectrum of the reflected light.
A plasmonic chip comprising:
- a layer of metal having,
- first plural grooves, and
- second plural grooves, formed at a non-zero angle relative to the first plural grooves,
- wherein the first and second plural grooves generate plasmon resonance patterns when illuminated with an incident light beam.
A method for determining a spectrum and polarization of a light, the method comprising:
- receiving an incident light beam at a plasmonic chip, which is configured to have first plural grooves and second plural grooves, which are formed at a non-zero angle relative to the first plural grooves, wherein the first and second plural grooves generate plasmon resonance patterns when illuminated with the incident light beam;
- generating a transmitted light beam or a reflected light beam that includes the plasmon resonance patterns;
- receiving the transmitted light beam or the reflected light beam at a light detector, which is configured to transform the transmitted light beam or the reflected light beam into an electronic reflected image, RI;
- and
- processing, with a processor that hosts a deep learning application, the electronic reflected image RI and simultaneously generating a spectrum of the reflected light beam and associated polarization.
