Pulsed anodic oxidation technique a new way of forming current blocking layers was successfully used in ridge-waveguide QW laser fabrication. We apply this method in 980nm VCSELs fabrication to form a high-quality native oxide current blocking layer which simplify the device process. A significant reduction of threshold current and a distinguished device performance are achieved. The 500m-diameter device has a current threshold as low as 0.48W. The maximum CW operation output power at room temperature is 1.48W. The lateral divergence angle //and vertical divergence angle are as low as 15.3 and 13.8 without side-lobes at a current of 6A.

An experimental EUVL system has been developed to investigate EUV imaging system design component fabrication assembly technique and experimental process. The system includes a laser produced plasma (LPP) source an ellipsoidal condenser a transmission mask a reduced projection optics and vacuum system. We designed a 10:1 reduction projection optics using Schwarzschild system with spherical mirrors to achieve 0.1m resolution. The Schwarzschild optics coated with Mo/Si multilayers was assembled with wavefront error (WFE) of 0.014 waves RMS at 632.8nm wavelength under computer-aided alignment method. Using this system a fine pattern of less than 0.25m covering a 0.1mm diameter image field of view was clearly replicated on resist-coated wafer.

Future optical communication systems will use more of the exceptional high bandwidth of optical fiber. Wavelength division multiplexing (WDM) systems are well suited to transport terabits of information via the fiber[1]. Multiplexers/ demultiplexers (MUX/DEMUX) are essential components for dense WDM systems. Several different kinds of multiplexer types have been developed in the past: (a) interference filters (b) fiber gratings and (c) planar lightwave circuit (PLC) MUX/DEMUXers[2 3]. The planar fabrication process of the last mentioned PLCs allows the realization of high performance filters with a large number of wavelength channels. Further an integration with other optical elements seems to be possible. Arrayed waveguide gratings (AWG) are a special kind of PLC-MUX/DEMUXers which are very attractive components for WDM systems because of their great flexibility in filter design[4 5]. Basically an AWG is an optical spectrograph built in planar waveguide technique. Typically AWGs works in a high grating order (50-250). For AWG multiplexer applications in communications systems a precise wavelength controllability and wavelength stability with long term is demanded. Recently a polymeric (especially fluorinated polymer with low optical absorption loss in the infrared region) AWG has attracted much attention because of its easy fabrication low cost possibility and a potential of integration with other polymer devices[6]. Standard AWGs however show a change of center wavelength with temperature. A method to prevent this temperature drift is to package the AWG together with a temperature controller in order to tune and fix the desired filter-wavelength. In this paper a 32-channel AWG was fabricated using a cross-linkable fluorinated poly (ether ether ketone) (FPEEK) its package technology and environmental stability were also discussed. 2005 IEEE.

Tungsten tellurite glasses doped with Er3+ Tm3+ Pr3+ and Ho3+ ions were prepared by melt quenching. The glass matrix was the same for all types of glasses and had a high sodium content in order to allow the fabrication of waveguides using an ion-exchange technique. The absorption spectra of the glasses were measured and the Judd-Ofelt parameters q were obtained from the experimental oscillator strengths of the f &rarr f transitions. Er3+ doped glasses showed a very high quantum efficiency when comparing the calculated radiative decay time with the measured lifetime of the 4I 13/2 metastable level. Ag+ Na+ ion-exchanged planar waveguides were successfully obtained in all types of glasses and characterized by the prism coupling technique. It turned out that the diffusion constant values are very similar for glasses containing different rare-earth ions with the same concentration while at least for the Er 3+ doped ones the diffusion constant changes with the ions concentration. 2004 Elsevier B.V.
