Modem silicon based computers process data in parallel using static memory and latching logic gates. If processing is to be possible in all-optical form we believe it is necessary to return to serial techniques since it has proved difficult to keep light still and obtain latching. Recent work at Colorado [1] has used these serial techniques to implement a stored program optoelectronic computer using a combination of electronic detection to control lithium niobate gates and optical fibres to provide the optical pathways. The key feature of the bit serial design is to use the time of flight of the light to provide a natural memory and to arrange for computation to occur by appropriate synchronisation of data and control pulses. One advantage of this approach is that the optical processing is scaleable in bit rate. In this paper we will describe an all-optical implementation of these techniques, based on the Nonlinear Optical Loop Mirror (NOLM)[2] switch architecture, with application to the operation of packet switched networks.","PeriodicalId":262564,"journal":{"name":"Nonlinear Guided Waves and Their Applications","volume":"23 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":"122581737","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}

In nonlinear self-switching, the power-dependent coupling of energy between two channels is caused by the imbalance of nonlinear gain/absorption and/or refractive-index between the two channels. In this paper, we report the experimental results of nonlinear polarization switching in an InGaAs/GaAs single quantum well(QW) GRINSCH optical amplifier. The amplifier consists of a 10 nm InGaAs well. On either side of the well, it includes a 40 nm GaAs barrier, an about 200 nm graded-index separate confinement layer with AlxGa1-xAs (x drops from 0.4 to 0), and an Al0.4Ga0.6As p/n type cladding. It lased at the threshold current 120 mA with 20 % duty cycle at 974 nm. The amplifier had a length about 300 μm and a ridge 50 μm wide for lateral guiding. The electro-luminescence in the TE (TM) mode was centered near 975 (940) nm, indicating the relative energy state of the heavy and light hole subbands. In the experiment, we used a Ti:Sapphire laser (Mirra 900) for femtosecond and cw optical signals. After the signals passed through the amplifier, their polarization status and power distributions between the TE and TM directions were recorded, as shown in Fig. 1.","PeriodicalId":262564,"journal":{"name":"Nonlinear Guided Waves and Their Applications","volume":"39 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":"122603066","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}

One of the most interesting effects is the ability of the spatial soliton, created by a strong beam inducing a sech-type refractive index profile, to behave as a waveguide, carrying a weak probe beam [2]. These waveguides can be made either with bright [2] or dark [3] spatial solitons. Such facts suggest further that colliding solitons might serve as X-junctions [5,6] and more generally as multiport devices. Several such devices have been analyzed to date [6,7]. The use of a probe beam with the same frequency as the pump is preferable because these devices then have no losses in the impact area of two solitons [6]. Moreover, a probe beam injected into one of the channels has no reflected component in this case. It passes through the impact area of the soliton collision and is distributed totally among the output channels. This is one of the essential properties of any ideal NxN switch. On the other hand, the use of a probe beam of the same frequency introduces the problem of its separation from the pump. Thus, from the experimental point of view it is more convenient to use a weak probe beam at different frequency [7], in which case the probe can be separated from the pump simply by spectral filtering. However, in this case “solitonic” devices like X-junctions or NxN switches lose their beauty because of losses in the soliton collision area [7] and the fact that an input beam can potentially be reflected into any of the input channels.","PeriodicalId":262564,"journal":{"name":"Nonlinear Guided Waves and Their Applications","volume":"42 6 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":"115625156","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}
