Real-time Oscilloscope for Novel Time-Frequency Photonics Research
Abstract
This proposal requests funds for purchase of a real-time oscilloscope that will support research entitled Novel Integrated Photonics Frequency Comb Phenomena that has been proposed to the Air Force Office of Scientific Research. Multifrequency optical signals known as frequency combs have had revolutionary impact in precision optics, with current and-or potential applications ranging from precision time-keeping and frequency standards to spectroscopy, environmental sensing, exoplanet detection, multiwavelength optical communications, generation of low timing jitter electrical signals, arbitrary waveform generation, and photonics-assisted radio-frequency signal processing. However, application outside specialized laboratories is hindered by size, environmental sensitivity, and cost. Optical frequency comb generation via nonlinear wave mixing in integrated photonic microresonators is an alternative approach that offers drastic size reductions that may eventually enable large scale applications. Parallel advances in integrated photonics technology are enabling other new opportunities, such as high-speed modulation on-chip with low loss. Together such as advances in nonlinear and high speed modulation on photonic chips open up new possibilities in photonic science and technology. Our proposed research would explore the science and multiple comb generation and applications and would utilize both nonlinearities and high speed modulation (usually only single comb generation, and either nonlinearity or modulation but not both, are considered). The results could provide impact for applications spanning readout of optical clocks for precision timing, optical ranging and imaging (lidar), sensing of the radiofrequency spectrum, and even quantum photonics technologies. We also expect substantial educational impact of the proposed equipment through graduate student research training. All of the approximately one dozen individuals in the PI’s research group benefit from the state-of-the-art facilities of the Ultrafast Optics and Fiber Communications Laboratory, and most are expected to benefit directly from the equipment requested in this proposal. To date the PI has advised 43 graduated Ph.D. students and 25 graduated Master’s students. Furthermore, six PhD graduates from Prof. Weiner’s group, as well as one former postdoc, are currently working in U.S. government laboratories. Many others are working in U.S. high tech industries. Accordingly, the proposed equipment is expected to have substantial benefit in training personnel who will be future research and technology leaders.
