Based on coupled nonlinear rate equations for carrier and photon densities, Lee et al (1) predicted a period doubling route to chaos in a directly modulated semiconductor laser as the modulation index increases. Kawaguchi(2) showed a similar route to chaos in the optical response of a directly modulated, self-pulsating semiconductor laser with a saturable absorber. While chaotic behavior has been experimentally observed in other lasers with modulated parameters3,4, chaos in a modulated diode laser still remains to be demonstrated. In this paper we report the observation of a subharmonic bifurcation and erratic behavior in the output of diode lasers subjected to deep modulation of the injection current. The experimentally measured bifurcation sequences differ considerably from the predicted scenarios. Non-deterministic quantum noise sources are believed to play an important role in the observed phenomena.","PeriodicalId":262701,"journal":{"name":"International Meeting on Instabilities and Dynamics of Lasers and Nonlinear Optical Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121173419","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}

Beyond the subfield of quantum optics, it is an important example of the decay of an unstable equilibrium state. Quantum fluctuations are necessary to trigger the decay of the atoms to the ground state; however, once begun the unstable nature of the process amplifies the tiny quantum fluctuations to macroscopic levels. Thus, superfluorescence gives us an insight into the nature of quantum stochastic processes.","PeriodicalId":262701,"journal":{"name":"International Meeting on Instabilities and Dynamics of Lasers and Nonlinear Optical Systems","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124291277","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}

Unfortunately, the conditions for observing chaotic emission require the bad cavity limit in conjunction with a large gain. Recently it was suggested by Weiss that far infrared lasers, owing to their narrow linewidths and large gains, could serve as the experimental work horse for the observation and study of optical chaos in the Lorenz system[2]. These lasers however exhibit complicated intensity dependent gain structure and therefore may introduce strong intensity dependent sidebands and inhomogeneous broadening effects[2],[3]. A key to the problem lies in the ability to drop the threshold for chaos in order that lower pump powers could result in the necessary gain for the transition to chaotic output.","PeriodicalId":262701,"journal":{"name":"International Meeting on Instabilities and Dynamics of Lasers and Nonlinear Optical Systems","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124756341","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}

An example is the prediction(1) that four-wave-mixing can generate squeezed states of an optical field where the variance in the two quadratures of the field are unequal. In order to observe squeezed states and utilize them in interferometric measurements this inequality in variances must be large (e.g. ≳ 50%). The large phase shifts required to achieve this regime of squeezing can be obtained near the threshold for oscillation of four-wave-mixing in an optical cavity.
