The ultrashort pulse pumped doublepass fiber Raman laser that we constructed (Fig. 1) generates an initial broad-band white-light stimulated spectrum as a result of the single-pass of the pump laser emission (from the direct channel) through a 100-pm-core-diameter 2.5-m-long multimode Raman OF. At the fiber output a highly intensive and white-light spot is observed that is formed due to the mutual action of the stimulated Raman scattering, self-phase modulation and four-photon mixing3 As a pumping source, a 110-fs-pulse-duration I-W-output-power 1-kHz-repetitionrate Tisapphire laser is used. From the initial spectrum by means of the dualchannel synchronously pumping regime of the double-pass fiber Raman laser, narrow-band spectral components are spatially dispersed and a tunable emission is generated over a wide range (400-1050 nm). This scheme potential is illustrated in Fig. 2, where typical spectral distributions of the fiber Raman laser emission including the amplified output and initial (from direct channel Ch. 1 only) spectra at X, = 810 nm is shown. The improvement of the output laser parameters is connected with an increase of the amplification and a decrease of laser spectral width by the optimization of laser pump parameters in the two channels and detailed investigation of spectral and temporal features of the proposed laser scheme. *Laser Science Research Group, Institute of Physical and Chemical Research (RlKEN), 2-1 Hirosawa, Wako-shi, Saitama 351-01, JAPAN 1.","PeriodicalId":260495,"journal":{"name":"Technical Digest CLEO/Pacific Rim '97 Pacific Rim Conference on Lasers and Electro-Optics","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115821428","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}

An unequal, arbitrary wavelength channel spacing is obtained by adjusting the output waveguide location\" for WDM systems avoiding the degradation due to four-wave mixing. The add/drop multiplexer, which switches arbitrary wavelength channels to \"through\" or \"add/drop\" ports, integrates four AWG multiplexers and thermo-o tic switches (TOSW) as shown in Fig. l! The input signals and signals to be added are demultiplexed by AWG 1 and AWG 2, respectively. TOSWs switch them to AWG 3 or AWG 4. AWG 3 and AWG 4 multiplex the different wavelength signals to the main output and drop port, respectively. An insertion loss of 8 dB and a crosstalk of -33 d B have been obtained. Integration of semiconductor devices with silica waveguides on Si substrates has been developed, thus enabling us to construct active WDM devices. A Bragg grating written in a silica waveguide by UV irradiation is utilized for the hybridintegrated multiwavelength laser. Figure 2 shows the configuration of an integrated extemal cavity laser array composed of gratings and laser diodes. Single-mode oscillation is attained with an output power of 1 mW from each laser.\" The oscillation wavelength, which is selected by the grating, is less dependent on temperature than that of semiconductor lasers such as the DFB-LD.

The format of the DVD-RAM, which has a storage capacity of 2.6 GB, was developed early this year. When the DVD-RAM is launched shortly, it is expected to penetrate into the market more rapidly than DVD-ROM. For the recording media of DVD-RAM, much more reliable phase-change recording material is being researched. The key technologies for DVD-RAM are high-density-recording, compact optical pick-up and highly reliable rewritable media. For high-density-recording, 635to 650-nm-wavelength laser diode, land/ groove recording technology and highly accurate recording laser pulse control technology for mark-edge recording have been developed. For compact optical pick-up, several types of DVD/CDcompatible optical pick-up, partially integrated optics, such as laser diode and photo-detector, and several types of hologram-used pick-up are proposed. For highly reliable rewritable media, the disk structure of phase-change-type media and its component are being investigated. Shorter wavelength laser diodes, multilayer recording technology and monolithic optics are major R&D areas being investigated, as possible future technologies for optical data storage. Using these technologies, a disk capacity of 15 to 20 GB and an average data rate of 15 to 20 Mbps will be possible in near future. It will be possible to record high-quality moving pictures of over two hours in length on smaller rewritable DVD.","PeriodicalId":260495,"journal":{"name":"Technical Digest CLEO/Pacific Rim '97 Pacific Rim Conference on Lasers and Electro-Optics","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127475846","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}
