Patent number: 10317342Abstract: Novel and advantageous systems and methods for performing nanometer-scale microscopy using graphene plasmons (GPs) are provided. Sub-diffraction microscopy can be achieved, taking advantage of the extremely small plasmon wavelength and low dissipation of GPs. Nanometer-scale resolution can be obtained under very weak light intensity, which is especially important in the imaging of biological systems.Type: GrantFiled: July 1, 2016Date of Patent: June 11, 2019Assignees: The Texas A&M University System, The National Centre for Applied Physics, KACSTInventors: Muhammad Suhail Zubairy, Mohammad D. Al-Amri, Xiaodong Zeng

Patent number: 9182348Abstract: The resonance fluorescence spectrum of a number of two-level atoms is driven by a gradient coherent laser field. In the weak dipole-dipole interaction region (separation less than ?/50), a very strong laser field may be applied such that the Rabi frequency is much larger than the dipole-dipole interaction energy. From the spectrum, the positions of each atom may be determined by just a few measurements. This sub-wavelength microscopy scheme is entirely based on far-field technique and it does not require point-by-point scanning, which makes the method more time-efficient. When two atoms are very close to each other (less than ?/50), the position information for each atom may still be obtained with very high accuracy provided that they are not too close to other atoms. The method may be extended to an arbitrarily large region without requiring more peak laser power and only a few measurements are required.Type: GrantFiled: February 8, 2013Date of Patent: November 10, 2015Assignees: The Texas A&M University System, King Absulaziz City for Science and TechnologyInventors: Muhammad Suhail Zubairy, Zeyang Liao, Mohammad D.

Patent number: 8891767Abstract: It has long been assumed in physics that for information to travel in empty space between two parties (the Sender and the Receiver), “physically real” entities have to travel between the parties. The recently discovered technique of interaction-free measurement—wherein the presence of an object is inferred without the object directly interacting with the interrogating light—has caused this basic assumption to be questioned. This technique has found application in quantum key distribution in the form of counterfactual quantum key distribution—albeit with limited efficiency. In the present invention, using the “chained” quantum Zeno effect, this logic is taken to its natural conclusion and, in the ideal limit, information can be transferred between the Sender and the Receiver without any physical particles whatsoever traveling between them.Type: GrantFiled: December 21, 2012Date of Patent: November 18, 2014Assignee: Texas A&M University SystemInventors: Muhammad Suhail Zubairy, Zhenghong Li, Mohammad D.

Patent number: 8574824Abstract: A sub-wavelength photolithographic method includes exposing a photoresist material to a stimulating electromagnetic source prior to further exposing the photoresist material to a dissociating electromagnetic source. The stimulating electromagnetic source induces Rabi oscillations in the photoresist material between a first molecular state and an excited molecular state. The subsequent exposure of the photoresist material to the dissociating electromagnetic source dissociates only those molecules that are in the excited state, altering the properties of the photoresist material in zones of excited state molecules. The resulting patterns therefore depend on the spatial distribution of the zones of excited state molecules induced by the stimulating electromagnetic source. The properties of the stimulating electromagnetic source are controlled to achieve a desired spatial distribution of zones of excited state molecules of the photoresist material.Type: GrantFiled: May 7, 2013Date of Patent: November 5, 2013Assignees: The Texas A&M University System, King Abdulaziz City for Science and TechnoloyInventors: Muhammad Suhail Zubairy, Zeyang Liao, Mohammad D.
