Title: Generation of a frequency comb and applications thereof

Abstract

Apparatus for generating a microwave frequency comb (MFC) in the DC tunneling current of a scanning tunneling microscope (STM) by fast optical rectification, cause by nonlinearity of the DC current vs. voltage curve for the tunneling junction, of regularly-spaced, short pulses of optical radiation from a focused mode-locked, ultrafast laser, directed onto the tunneling junction, is described. Application of the MFC to high resolution dopant profiling in semiconductors is simulated. Application of the MFC to other measurements is described.

Light beam frequency comb generator

Patent Priatko, Gordon J [Cupertino, CA]; Kaskey, Jeffrey A [Livermore, CA]

A light beam frequency comb generator uses an acousto-optic modulator to generate a plurality of light beams with frequencies which are uniformly separated and possess common noise and drift characteristics. A well collimated monochromatic input light beam is passed through this modulator to produce a set of both frequency shifted and unshifted optical beams. An optical system directs one or more frequency shifted beams along a path which is parallel to the path of the input light beam such that the frequency shifted beams are made incident on the modulator proximate to but separated from the point of incidence ofmore » « less

Device and method for generating a beam of acoustic energy from a borehole, and applications thereof

Patent Vu, Cung Khac; Sinha, Dipen N.; Pantea, Cristian; ...

In some aspects of the invention, a method of generating a beam of acoustic energy in a borehole is disclosed. The method includes generating a first acoustic wave at a first frequency; generating a second acoustic wave at a second frequency different than the first frequency, wherein the first acoustic wave and second acoustic wave are generated by at least one transducer carried by a tool located within the borehole; transmitting the first and the second acoustic waves into an acoustically non-linear medium, wherein the composition of the non-linear medium produces a collimated beam by a non-linear mixing of themore » « less

Methods of generation of pores in sheets of hexagonal boron nitride and applications thereof

Patent Zettl, Alexander K.; Dunn, Gabriel P.; Gilbert, Stephen M.

This disclosure provides systems, methods, and apparatus related to few-layer and monolayer hexagonal boron nitride having a pore therein. In one aspect, a method comprises providing a sheet of hexagonal boron nitride (h-BN). A defect is created in the sheet of h-BN. The sheet of h-BN is heated to a temperature above about 500° C. The defect in the sheet of h-BN is irradiated with charged particles to enlarge the defect to a hexagonal-shaped pore or a parallelogram-shaped pore in the sheet of h-BN.
