This is because SDM has more advantage in cost and power consumption than TDM, when the transmission distance is rather short, i.e. less than a few hundred meters. VCSEL and smart pixel arrays are very important for constructing optical interconnection systems because they can emit, switch and process a number of broadband optical signals simultaneously. This paper reviews VCSELs and VCSEL-based smart pixels, and discusses the issues for their application to optical interconnections. VCSELs and smart pixels are applicable to three types of parallel optical interconnections: 1) parallel optical fiber link-the optical signals from the SEL array are transmitted through a fiber ribbon for distances less than a few hundred meters; 2) free-space optical interconnects-high-density optical signals from a two-dimensional SEL array are distributed into several ports for distance shorter than one meter; 3) reconfigurable optical interconnects nterconnect patterns among processors are changed dynamically by means of free-space photonic switching networks.","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115352240","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":null,"pages":null},"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}

These femtosecond sources can be used to great advantage in many communications and information processing applications. Interestingly enough, most of these applications are not related to the speed of these pulses, but rather use some other aspect of femtosecond laser pulses such as large spectral bandwidth, spectral coherence, intensity, short coherent length, or signal-to-noise advantages. For example, the 3 THz spectral bandwidth of a 100 fs laser pulse is wide enough to support 30 WDM channels spaced at 100 GHz, all covered by a single laser source. These channels can now be modulated using either a modulator array or even only a single modulator when the femtosecond pulses are chirped by propagation in optical fiber, as in chirped-pulse WDM. Using diode-pumped erbium fiber lasers, such a femtosecond WDM source can support many channels in a cost effective way. A single TDM modulator running at a multiple of the repetition rate of the laser can now both define as well as encode data onto the WDM channels sequentially. Interesting applications also result when we take advantage of space-time analogies in optical systems involving short pulses. This principle can be used for all-optical packet header recognition of terabit-per-second data streams. Using computer-generated holograms (CGH), we have generated and subsequently recognized 8-bit pulse sequences at a 1 Tb/s data rate.","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121662153","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}

Implementation of coherent detection in optical subscriber network for TV distribution and broad-band ISDN services have been demonstrated. Monolithically integrated coherent receivers is attractive for such applications, due to the dramatic cost reduction by eliminating packaging of hybrid components. However, the device structure as well as fabrication process of integrated receivers are usually quite complex and the yield is considerably low. We proposed and demonstrated an integrated device with simple structure can perform both transmitting and receiving functions with very high receiver sensitivity. The device structure and possible configurations as customer transceiver in coherent multi-carrier (CMC) distribution system is shown. The device is composed of a tunable DBR laser as a local oscillator (LO) and an integrated detector. This allows one to fully utilize the wavelength tuning range to achieve highly dense spaced WDM coherent systems.","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121697363","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}
