摘要： An apparatus and method for synthesizing waveforms with arbitrary amplitude, frequency, and phase modulation. Pulses from a broadband (supercontinuum) optical source are filtered into a plurality of wavelength channels, and the intensity of each wavelength channel is adjusted to an appropriate level depending on the desired shape of the envelope of the output pulse. The envelope of the sampling wavelength channels can be stretched, compressed, or inverted in the time domain later using a dispersive medium. After time domain manipulation, the optical pulse train is observed with a combination of high-speed photodetectors and a radio frequency low-pass filter, a low-speed photodetector.

摘要： An apparatus and method for measuring Raman-type spectra using optical dispersion to convert an optical spectrum into a waveform which can be detected directly in the time domain without the use of a conventional spectrometer. In the example of stimulated Raman spectroscopy, the apparatus and method exposes a sample to a chirped, pulsed probe beam and a Raman pump beam and the resulting Raman spectra is detected by an optical detector in the time domain, and analyzed. Alternatively, the Raman spectra from the probe and pump beams is chirped with a dispersive element prior to detection and analysis. Each probe pulse provides a snapshot of the Raman spectrum that is sampled in time so that neither repetitive waveforms nor static samples are required. Therefore, high speed acquisitions and high throughput assays can be conducted. To facilitate detection, these spectral signals can also be amplified using distributed Raman amplification directly in the dispersive element.

摘要： A system and method to chromomodally generate dispersion in light waves. The system and method may be used to control dispersive effects of an optical element such as a single-mode fiber. A light beam from the optical element is first collimated and then directed on to a spatially diffractive element where it is spatially dispersed into various chromatic frequency components. This frequency-separated light is then imparted onto a dispersion slope equalizer, and then passed into a highly multimode waveguide, where it is further dispersed. The light is then collected and focused back into an outgoing fiber-optic or other optical device.

摘要： We describe methods and apparatus for high-speed high-contrast imaging one-, two- and three-dimensional imaging enabled by differential interference contrast time encoded amplified microscopy of transparent media without the need for chemical staining, that are suitable for a broad range of applications from semiconductor process monitoring to blood screening. Our methods and apparatus build on a unique combination of serial time-encoded amplified microscopy (STEAM) and differential interference contrast (DIC) microscopy. These methods and apparatus are ideally suited for identification of rare diseased cells in a large population of healthy cells and have the potential to revolutionize blood analysis and pathology including identification of cancer cells, such as Circulating Tumor Cells (CTC) in early stage disease.

摘要： A barcode reading apparatus and method in which the spectrum of a probe light is first Fourier-transformed into space, directed upon a barcode, and then Fourier-transformed converting the spectrally encoded barcode pattern to a time domain waveform. In one implementation, the Fourier transformation from the spectrum domain into a spatial domain is performed by a dispersive element, while the Fourier transformation from the spectrally encoded barcode pattern to a time domain waveform is performed by group-velocity dispersion (GVD). The temporally encoded barcode pattern is detected by a photodetector, digitized by a digitizer, and analyzed by a digital signal processor. The invention is applicable to a number of fields which involve the reading of one- and two-dimensional barcodes, displacement sensing, surface measurements, measurement of width and gap, flow cytometry, reading of optical media, presence or absence detection, and other related fields.

摘要： A time-stretched enhanced recording scope (TiSER) is described using time stretch analog-to-digital conversion in a real-time burst mode. A chirped optical signal is modulated in response to receiving segments of an input signal. The optical signal with its modulated input signal, is stretched through an optical medium and digitized to represent the waveform segment. TiSER provides ultra-fast real-time sampling within short segment bursts of the original input signal while providing an ability to detect non-repetitive events. Methods and apparatus are also described for providing real-time information about inter-symbol information (ISI), rapidly determining bit-error rates (BER), performing time-domain reflectometry (TDR), generating eye diagrams for serial data, facilitating digital correction of data, clock recovery, optical carrier phase recovery, and otherwise increasing the speed and/or accuracy of a diverse range of high-speed signal measurement and processing activities.

摘要： A silicon Raman laser that can be electrically switched or modulated and which demonstrates active mode-locking capabilities. The laser can be used with a more traditional glass fiber cavity, or can be fabricated on a single chip with a cavity, or a cascaded cavity, in which the chip fabrication is compatible with widely used silicon chip fabrication methods. The laser can be tuned by adjusting a source pump laser to product specific output and operates at room temperature. Output is present in the near- and mid-infrared frequency range, and the laser can simultaneously produce output at the Stokes and at the anti-Stokes wavelengths.
