In particular, spatial solitary waves in nonlinear waveguides are of cunent interest because of a novel, very interesting optical bistable and switching effect [2,3]. The soliton coupler, suggested by Heartley et al., is one of the most exciting examples to utilize the threshold effect of spatial soliton emission for the sharp switching devices [4]. The majority of theoretical work to date, however, has been restricted to the planar waveguides consisting of the linear thin film bounded by one or two nonlinear semi-infinite media [2,3]. In this work, we consider a planar waveguide consisting of the adjoining linear and nonlinear guiding thin film covered by two linear semi-infinite media, as shown in Fig. 1. The waveguide configuration has distinctive features: (i) due to the confinement of the nonlinearity, the emitted nonlinear wave is generally a solitary wave rather than a soliton and (ii) it can control the emitted power of the solitary wave and the hysteresis of the optical bistability by varying the thickness of the nonlinear thin film.","PeriodicalId":262564,"journal":{"name":"Nonlinear Guided Waves and Their Applications","volume":"1 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":"129446787","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}

This condition can be met in fused silica fibers beyond the zero-dispersion wavelength. Unfortunately, semiconductors that are fairly attractive for all-optical elements because of their large off-resonant nonlinearities (below half the band gap) exhibit a huge normal GVD (D≈1000ps2/km) thus prohibiting the formation of bright solitons. Hence, there is a great deal of interest to identify smart device concepts that allow for the overcompensation of the wrong material dispersion. Such concepts could be used to avoid the experimentally observed pulse break up in nonlinear AlGaAs directional couplers by using temporal solitons [1]. Moreover, spatio-temporal objects (light bullets) [2] could be studied because the required interplay of diffraction, anomalous dispersion and focusing nonlinearity would occur in properly designed planar waveguide structures. Because the device length of semiconductor waveguides is limited to about 2\" the anomalous dispersion should exceed some thousands of ps2/km for pulse lengths of some hundred fs.","PeriodicalId":262564,"journal":{"name":"Nonlinear Guided Waves and Their Applications","volume":"1 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":"129482069","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}

Several authors have recently reported success with the proof-of-concept demonstrations of passive and laser-integrated nonlinear waveguide devices as wavelength sensors for frequency control of DFB lasers.[1], parametric spectrometers for DWDM demultiplexing [2] and serial-to-parallel-convertors for 100Gb/s TDM demultiplexing [3]. From the view point of practical systems implementation, one key parameter for these devices is the overall SF conversion efficiency because it ultimately dictates the signal-to-noise ratio and bit error rate (BER). For devices using quasi-phase-matched (QPM) AlGaAs multilayers structure, the efficiency is further affected by two somewhat related factors: the absorption of the SF light by the waveguide materials and the coupling efficiency of the input signal. Since the band gap of GaAs is smaller than the SF light photon energy for the wavelength that we are interested in, strong absorption occurs as the SF light propagating towards the waveguide surface. On the other hand, for thin guides, large mismatchs between waveguide thickness and fiber core size results large coupling losses. In order to improve the optical coupling, we have recently demonstrated a device employing a nonlinear antiresonant reflecting optical waveguide (NARROW) geometry [4]. The NARROW structure allows large coupling efficiency with fibers by providing a thick guiding core with high modal discrimination. We have obtained coupling efficiency of ~15% from a 8-μm core diameter fiber to a 2.6 μm thick NARROW device. Further improvement in coupling efficiency, however, is limited by the SF light absorption of the thick nonlinear layers.","PeriodicalId":262564,"journal":{"name":"Nonlinear Guided Waves and Their Applications","volume":"65 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":"129535099","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}
