These devices would be useful for ultrafast serial processing: applications include routing and time-domain demultiplexing in telecommunications transmission networks as well as local area networks, providing key functions where the system bottleneck is set by the bandwidth of a few critical components. All-optical time-domain switching and routing is a natural complement to wavelength switching in offering massive transport capability: therefore, it would be advisable that optically-controlled technologies be compatible with wavelength switching implementations. The discussion here is restricted to nonlinear, guided-wave, passive devices based on semiconductors, and, specifically, on semiconductor quantum wells (SQWs).","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131867449","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}

At very high intensity, laser light can be coupled directly to a low density gas through multiphoton ionization. At the intensities of our pump, the radiation must be absorbed by inverse bremsstrahlung, which is inefficient at low density. To improve the overall efficiency, an optic was designed which integrates an axicon and a reflective tube such that unabsorbed pump radiation is repeatedly refocused on axis, permitting the creation of extended line foci in gases. Experimentally it was found that 6 cm sparks could be created in 200-760 torr argon with very high pump absorption, particularly on a second, delayed pulse. To investigate the coupling of pump laser energy into the plasma column, and subsequent plasma development, a computational model has been developed. Initial plasma formation occurs as a result of multiphoton ionization. Subsequent heating of the plasma occurs by inverse bremsstrahlung absorption, while higher stages of ionization are obtained through collisional ionization. A one-dimensional three-fluid hydrodynamic model, which incorporates collisions between charged particles and neutral atoms, is used to predict plasma expansion into the surrounding gas, while the coupling of absorbed energy to the plasma front is modeled by flux-limited electron thermal conduction.","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124708937","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}

Wavelength conversion by quasi-phase-matched difference frequency generation (DFG) in a wafer-bonded AlGaAs waveguide has been demonstrated. The wide conversion bandwidth (/spl sim/90 nm), polarization diversified operation, and polarization independent conversion efficiency indicate its potential for WDM network applications. Spectral inversion and linear conversion properties also imply its capability to accommodate all signal formats and protocols including analog and frequency modulation. A significant improvement in the conversion efficiency is expected from reduction of scattering losses by improved OMCVD growth and fabrication processes.","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134477708","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}

Photocurrent spectroscopy, belonging to the traditional methods of semiconductor physics, gained an entirely new range of application by employing an optical near-field microscope as the optical excitation source. Thus near-field optical beam induced current (NOBIC) spectroscopy has been developed. It combines the spatial resolution of less than some 100 nm of electron beam based techniques such as electron beam induced current (EBIC) with the advantages of providing selective excitation of the laser structure if a tunable wavelength excitation source is used and being completely non-destructive. Here, a NOBIC study of different GaAs-AlGaAs high power diode laser array structures such as double quantum well (DQW) graded index separate confinement heterostructures as well as step index AlGaAs structures is presented.","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122429583","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}
