Publication number: 20210242654Abstract: The present invention provides octave-spanning optical frequency combs. The octave-spanning optical frequency combs employ microresonators having improved stability using a smaller form factor. In some embodiments, the octave-spanning optical frequency combs are fabricated using aluminum nitride (AlN). AlN is a more robust Kerr material for generating octave-spanning soliton comb (e.g., 1.5 octaves or more).Type: ApplicationFiled: February 3, 2021Publication date: August 5, 2021Inventors: Hongxing Tang, Xianwen Liu, Joshua Surya

Patent number: 9341779Abstract: Devices which operate on gradient optical forces, in particular, nanoscale mechanical devices which are actuable by gradient optical forces. Such a device comprises a waveguide and a dielectric body, with at least a portion of the waveguide separated from the dielectric body at a distance which permits evanescent coupling of an optical mode within the waveguide to the dielectric body. This results in an optical force which acts on the waveguide and which can be exploited in a variety of devices on a nano scale, including all-optical switches, photonic transistors, tuneable couplers, optical attenuators and tuneable phase shifters.Type: GrantFiled: August 6, 2013Date of Patent: May 17, 2016Assignee: Yale UniversityInventors: Hongxing Tang, Mo Li, Wolfram Pernice, Chi Xiong

Patent number: 8827548Abstract: A microfluidic embedded nanoelectromechanical system (NEMs) force sensor provides an electrical readout. The force sensor contains a deformable member that is integrated with a strain sensor. The strain sensor converts a deformation of the deformable member into an electrical signal. A microfluidic channel encapsulates the force sensor, controls a fluidic environment around the force sensor, and improves the read out. In addition, a microfluidic embedded vacuum insulated biocalorimeter is provided. A calorimeter chamber contains a parylene membrane. Both sides of the chamber are under vacuum during measurement of a sample. A microfluidic cannel (built from parylene) is used to deliver a sample to the chamber. A thermopile, used as a thermometer is located between two layers of parylene.Type: GrantFiled: May 18, 2011Date of Patent: September 9, 2014Assignee: California Institute of TechnologyInventors: Michael L.

Publication number: 20140186648Abstract: The present invention relates to materials, methods and apparatuses for performing imprint lithography using amorphous metallic materials. The amorphous metallic materials can be employed as imprint media and thermoplastic forming processes are applied during the pattern transfer procedure to produce micron scale and nanoscale patterns in the amorphous metallic layer. The pattern transfer is in the form of direct mask embossing or through a serial nano-indentation process. A rewriting process is also disclosed, which involves an erasing mechanism that is accomplished by means of a second thermoplastic forming process. The amorphous metallic materials may also be used directly as an embossing mold in imprint lithography to allow high volume imprint nano-manufacturing. This invention also comprises of a method of smoothening surfaces under the action of the surface tension alone.Type: ApplicationFiled: January 21, 2014Publication date: July 3, 2014Applicant: Yale UniversityInventors: Jan Schroers, Golden Kumar, Hongxing Tang

Patent number: 7959873Abstract: A biosensor is comprised of a free and a biofunctionalized recognition self-sensing nanocantilever, a dock adjacent to the ends of the nanocantilevers, and a gap between the nanocantilevers and dock. The self-sensing cantilevers each include a semiconductor piezoresistor defined in a pair of legs about which the cantilevers flex. A bias power or current is applied to the piezoresistor. The sensitivity of the cantilevers is optimized for a given ambient temperature and geometry of the cantilevers and dock by minimizing the force spectral density, SF, of the cantilevers to determine the optimum bias power, Pin. A sub-aN/?Hz force sensitivity is obtained by scaling down the dimensions of the cantilevers and supplying an optimum bias power as a function of temperature and geometry.Type: GrantFiled: July 20, 2006Date of Patent: June 14, 2011Assignee: California Institute of TechnologyInventors: Michael Roukes, Hongxing Tang, Jessica Arlett, James Maloney, Benjamin Gudlewski
