  • Patent number: 9170203
    Abstract: Raman emissions from a sample may be enhanced by using a microsphere to confine the impinging radiation into a photonic nanojet and thereby increase the intensity of the radiation that is striking the sample. The amount of enhancement may be improved by configuring the diameter and refractive index of the microspheres in conjunction with the dispersion and the wavelength of the radiation to increase the intensity of the beam of radiation in the photonic nanojet.
    Type: Grant
    Filed: May 16, 2012
    Date of Patent: October 27, 2015
    Assignee: Indian Institute of Technology Madras
    Inventors: Prem Ballabh Bisht, Venkata Ramanaiah Dantham, Raman Namboodiri
