TECHNOLOGY/BUSINESS OPPORTUNITY Slanted Light Interrogation for Cross-correlated Encoder Recording (SLICER) Techniques for recording transient optical signals in a time regime of picoseconds to nanoseconds Opportunity : Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a research partnership to collaborate to further develop this technology and license intellectual property rights to ultimately commercialize this technology. Background : Currently, there are few reliable methods for recording ultrafast single-shot events over long record lengths. Several applications require measurements of 1 picosecond (ps) or better temporal resolution, with record lengths up to 1 nanosecond (ns). The majority of current measurement systems rely on high electronic bandwidth to perform high speed measurements. These approaches generally trade off amplitude resolution for temporal resolution and currently only achieve at best 10ps temporal resolution at the maximum tradeoff. Description : LLNL researchers have demonstrated a novel single-shot recording technology for transient optical signals in a time regime of picoseconds to nanoseconds for which currently there is a significant instrumentation gap. The optical switching capability of optical semiconductors can be exploited in a pump-probe style architecture, where 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. The integrating response of the rapidly excited, but persistent carriers is differentiated by probing with and destructively interfering two time staggered signal replicas. Advantages : There are several advantages of the SLICER setup: •1) 1) The strength of the nonlinear effect can be very high in many semiconductors. Further, the extremely broad range of semiconductor materials allows for measurement of signals across virtually the entire spectrum for which standard optical elements are available. •2 2) Semiconductor materials can typically be made much larger than χ (2) nonlinear optical crystals, resulting in scalability to long records lengths (limited by time of flight). •3) 3) There is no stringent angular sensitivity on the pump or signal, allowing for aggressive crossing angles to be used. Potential Applications : SLICER is a one dimensional temporal recorder that exclusively uses the X axis of the wafer to encode information. However, the Y dimension of the wafer is available for use for encoding additional information; many novel devices can be created by reconfiguring what information is encoded in the X and Y axes. LLNL utilizes the SLICER techniques for observation of the ARC & NIF pulse in time and long record single shot cross correlator. Development Status: LLNL has filed a patent application for its SLICER invention that has been reduced to practice. Additional technical information can be made available upon request as appropriate. LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace. All licensing activities are conducted under policies relating to the strict nondisclosure of company proprietary information. Please visit the IPO website at https://ipo.llnl.gov/resources for more information on working with LLNL and the industrial partnering and technology transfer process. Note: THIS IS NOT A PROCUREMENT. Companies interested in commercializing LLNL's SLICER technology should provide a written statement of interest, which includes the following: 1. Company Name and address. 2. The name, address, and telephone number of a point of contact. 3. A description of corporate expertise and facilities relevant to commercializing this technology. Written responses should be directed to: Lawrence Livermore National Laboratory Industrial Partnerships Office P.O. Box 808, L-795 Livermore, CA 94551-0808 Attention: FBO 345-17 Please provide your written statement within thirty (30) days from the date this announcement is published to ensure consideration of your interest in LLNL's SLICER technology.
