Using ASE noise as the signal carrier, optical steganography effectively hides a stealth channel in both the time domain and the frequency domain. Coherent detection is used at the receiver of the stealth channel. Because ASE noise has short coherence length and random phase, it only interferes with itself within a very short range. Coherent detection requires the stealth transmitter and stealth receiver to precisely match the optical delay, which generates a large key space for the stealth channel. Several methods to further improve optical steganography, signal to noise ratio, compatibilitywith the public channel, and applications of the stealth channel are also summarized in this review paper.","PeriodicalId":317947,"journal":{"name":"Coherent Optical Phenomena","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124791264","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}

It is shown that Kerr nonlinearity can be controlled competently by tuning the energy splitting of the two excited states (the coupling strength of the tunneling), i.e. Fano-type interference. This outcome may be used for optimizing and controlling long wavelength optical switching processes in QW solid-state systems, which is much more useful than that currently used in atomic systems because of its flexible design and the controllable interference strength.","PeriodicalId":317947,"journal":{"name":"Coherent Optical Phenomena","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132656195","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}
