All optical pulse cmeasurement techniques necessarily fail in multi-shot measurements of unstable pulse trains because the measurement can only provide a single result, despite of the presence of many different pulse shapes. At the very least, however, the technique should provide a reasonable estimate of a typical pulse in the train and indicate the train's stability. While frequency-resolved optical...
We simulate multi-shot measurements of trains of pulses with unstable shapes using SPIDER, SRSI, SHG FROG, PG FROG, and XFROG. Interferometric methods measure only the coherent artifact, while FROG methods better approximate the trains.
We demonstrate double blind FROG for single-shot measurement of two non-trivial pulses. The pulse-retrieval algorithm is simple and robust, even for complex pulses.
We demonstrate a simple method for simultaneously and robustly measuring two arbitrary, potentially very complex pulses, which we call “double-blind” FROG. It uses the standard FROG algorithm and can operate on a single shot.
A sensor structure based on surface plasmon resonance (SPR) and carbon nanotubes (CNTs) is designed and developed. The device is an ultrasensitive wireless sensor operating in microwave frequencies utilizing the gas sensitivity of CNT mixtures. The sensor consists of a corrugated aluminum plate whose surface is periodically covered with a thin layer of the CNT materials. The incident TM-polarized...
