| 121 | ALL OPTICAL SAMPLING BY SLANTED LIGHT INTERROGATION FOR CROSS-CORRELATED ENCODED RECORDING (SLICER) | US15593256 | 2017-05-11 | US20180329272A1 | 2018-11-15 | Ryan D. Muir; John E. Heebner |
| Single-shot transient optical signals are recorded in a time regime of picoseconds to nanosecond. An auxiliary pump beam is crossed through the signal to sample a diagonal ‘slice’ of space-time, analogous to a rolling shutter. The slice is then imaged onto an ordinary camera, where the recorded spatial trace is a direct representation of the time content of the signal. The pump samples the signal by optically exciting carriers that modify the refractive index in a conventional semiconductor wafer. Through use of birefringent retarders surrounding the wafer, the integrating response of the rapidly excited but persistent carriers is differentiated by probing with two polarization-encoded time-staggered signal replicas that are recombined to interfere destructively. | ||||||

| 124 | Low-loss high-repetition-rate pulsed laser modulator | US15001244 | 2016-01-20 | US09720176B2 | 2017-08-01 | Wei Shi; Zhenhua Yu; Xinzheng Dong |
| The present invention provides a low-loss high-repetition-rate pulsed laser modulator comprising: a 2*2, 1:1 coupler; a light delay module; a 1*2, 1:1 coupler. The present invention can modulate a low-repetition-rate pulsed laser to be a high-repetition-rate pulsed laser. The basic principle is: one beam of low-repetition-rate pulsed laser can be divided into two beams with the same light intensity by a 1*2, 1:1 coupler; control the two beams of light to have an optical path difference so that when they are coupled into a 2*2, 1:1 coupler, a double pulse repetition rate can be obtained; In the same way, when the two beams of light from former 2*2, 1:1 coupler, with another different optical path difference are coupled into the next 2*2, 1:1 coupler, a double pulse repetition rate can be obtained again; when we obtain the repetition rate we need, a 1*2, 1:1 coupler instead is connected to couple the two beams of light into one beam with a double repetition rate. | ||||||

| 128 | Uncooled Operation of Microresonator Devices | US14217663 | 2014-03-18 | US20160161676A1 | 2016-06-09 | Paul A. Morton; Jacob Khurgin |
| This invention removes the need to provide temperature control for an optical time delay chip, which is usually provided by a thermo-electric-cooler, in order to significantly reduce the power dissipation of the device and allow ‘uncooled’ operation. Uncooled operation is achieved by monitoring the temperature of the chip, and changing the tuning of each microresonator within the device in order to continue providing the required time delay as the temperature is varied. This invention takes advantage of the fact that microresonators provide a series of resonant wavelengths over a wide wavelength range, so that the closest resonance wavelength below the operating wavelength can always be tuned up to that wavelength. When the device temperature changes, this is accounted for by both the choice of resonance wavelengths and the tuning for each of the microresonators in the device, in order to keep the correct tunable delay. | ||||||

| 130 | System and method for synchronizing light pulses at a selected location | US14240866 | 2012-08-28 | US09164352B2 | 2015-10-20 | Alain Villeneuve |
| A system (100) for spatially addressing the synchronization of two light pulses (118, 120) having a respective wavelength. The system (100) includes two light sources (110, 114), each one generating one of the light pulses (118, 120) in response to receiving a respective source trigger. The light pulses (118, 120) are combined and then distributed in many light guiding elements (104) in which propagation at the first and second wavelength takes a different amount of time, the differences between the propagation times at the first and second wavelengths differing between the light guiding elements (104). The source triggers are separated from each other by a variable delay in order to cause simultaneous arrival of the first and second pulses (118, 120) at the output of only one of the light guiding elements (104). | ||||||
| 131 | OPTICAL DELAY LINE FORMED AS SURFACE NANOSCALE AXIAL PHOTONIC DEVICE | US14267058 | 2014-05-01 | US20150277049A1 | 2015-10-01 | Mikhail Sumetsky |
| A surface nanoscale axial photonic (SNAP) device in the form of an optical bottle resonator is configured to exhibit a semi-parabolic profile (in terms of a change in radius along the longitudinal direction of the fiber). It has been found that this semi-parabolic profile provides the ability to create the dispersionless delay of optical pulses, where “dispersionless” in this case is considered to mean that the pulse retains its same shape with minimal distortions as it passes back and forth within the bottle resonator (i.e., minimal pulse-broadening). Delays on the order of several nanoseconds have been created within these semi-parabolic-shaped SNAP bottle resonators of about 3 mm in length (as compared with prior art microresonator devices' ability to create delays no greater that 1 ns, at best). | ||||||
