Patent number: 11841274Abstract: The invention offers high resolution and accuracy for nanoscale device characterization from ultraviolet through microwave wavelengths. Instead of collecting light after emission in near-field that decays to far-field, the present invention directly couples the near-field waves to a polaritonic-coated probe. The polaritonic coating can be formed on an wavelength tuned optical fiber to receive the coupled emission and form polaritons, including plasmons, phonons, and magnons, using the polaritonic material. The polaritons propagate along the probe decay back into the fiber core without substantial losses to far-field and are transmitted to a detector, such as a spectroscope. The coupling of the near-field energy to emission detected through the tip apex of fiber can be expressed as emission spectra. Through mapping with other spatial points, multi-dimensional displays and other information can be provided. The resolution can be less than 100 nanometers, including an order of magnitude less than 100 nanometers.Type: GrantFiled: October 11, 2021Date of Patent: December 12, 2023Assignee: BAYLOR UNIVERSITYInventors: Zhenrong Zhang, Blake Birmingham, Khant Minn

Publication number: 20220011172Abstract: The invention offers high resolution and accuracy for nanoscale temperature mapping. Instead of collecting light after emission in near-field that decays to far-field, the present invention directly couples the near-field waves to a polaritonic-coated infrared probe. The polaritonic coating can be formed on an IR-tuned optical fiber to receive the coupled IR radiation and form polaritons, including plasmons or phonons, using the IR polaritonic material. The IR polaritons propagate along the probe decay back into the fiber core without substantial losses to far-field and are transmitted to a detector, such as a spectroscope. The coupling of the near-field energy to emission detected through the tip apex of fiber can be expressed as emission spectra. Through mapping with other spatial points, multi-dimensional displays and other information can be provided. The resolution can be less than 100 nanometers, such as at least an order of magnitude less than 100 nanometers.Type: ApplicationFiled: September 28, 2021Publication date: January 13, 2022Applicant: BAYLOR UNIVERSITYInventors: Zhenrong ZHANG, Blake BIRMINGHAM, Khant MINN

Patent number: 10145799Abstract: The present disclosure provides a system and method for a fiber-coupled, metal-tip chemical imaging spectroscopy. The system couples the electromagnetic radiation (EMR), such as laser light, through an optical fiber to a conductive tip for both EMR excitation to the sample through the conductive tip and EMR signal collection from the sample through the conductive tip. The system and method effectively eliminates the need for an optical alignment between the EMR source and the tip, and still offers the customary spatial resolution of a non-coupled system.Type: GrantFiled: February 22, 2018Date of Patent: December 4, 2018Assignee: Baylor UniversityInventors: Zhenrong Zhang, Blake Birmingham, Ho Wai Howard Lee
