One of the most promising approaches to capture such processes is time-resolved x-ray-diffractive imaging. Modern x-ray light sources, such as the upcoming free-electron lasers with very large photon fluxes such as the European XFEL, LCLS II, or synchrotrons, operate at high repetition rates with ten-thousands to millions of pulses per second, sometimes in burst modes. To allow for efficient measurements, the aligned molecules should be available for all of these pulses. However, the necessary electric field strengths for strong adiabatic alignment of gas-phase ensembles of molecules exceeds 1010 W/cm2 and this field strength must be applied over durations comparable to the rotation periods of the molecules of hundreds of picoseconds to even nanoseconds. So far, these intensities are only available from pulsed amplifier systems with repetition rates in the few-Hz to low-kHz range, which does not allow for providing aligned molecules for all pulses of the x-ray probe sources. Thus, it prohibits efficient use of these sources.","PeriodicalId":375462,"journal":{"name":"2015 IEEE Photonics Conference (IPC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126400980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modulation bandwidth for free-running VCSELs typically ranges from few to twenty GHz. An interesting discovery is that modulation bandwidth may be appreciably improved with coherently coupled arrays. Recently we reported the ability to tune 2-1 phased, photonic crystal VCSEL arrays into various regions of coherently coupled operation and its utilization for producing greatly enhanced resonance frequency and modulation bandwidth. We have since applied dynamic coupled mode theory to evaluate relevant aspects of modulation response and locking range dynamics observed from coherently coupled 2-1 arrays.","PeriodicalId":375462,"journal":{"name":"2015 IEEE Photonics Conference (IPC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126479210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
