Summary form only given. Parallel optical interconnect systems are becoming extremely important for high-speed optical data communications. A planar microlens (PML) array is a key component for alignment-free systems. In this study, we investigated its optical characteristics for stacked planar optics, which is aligned on micro-optical bench (MOB).

Summary form only given. In 1993 Basistiy et al. doubled the frequency of the Laguerre-Gauss optical vortex. The parametric interactions in nonlinear crystals may provide an efficient way of vortex transformation. The nearly nondiffracting Bessel vortices are of special interest. We investigate type II phase-matched second harmonic (SH) generation of the Bessel vortex in KTP and LiNbO/sub 3/ crystals.

Summary form only given. The achievement of a stable optical pulse source in the 1.5 /spl mu/m wavelength region with a high repetition rate is extremely important for its use as a transmitter in soliton-based optical transmission systems. In recent work, we proposed and demonstrated a novel non-resonant technique for the generation of high-bit-rate transform-limited pulse trains, based on asynchronous FM of an Er-Yb laser with external spectral filtering by a Bragg fiber grating. This technique enables to relax the strict constraint of cavity length control needed with conventional active mode-locking methods. In this work we present a comparative analysis of pulse train stability based on BER measurements, of a 2.5-GHz frequency-modulated Er-Yb laser operated in FM mode-locking (synchronous modulation) and in the FM regime (asynchronous modulation), and demonstrate the significant lower sensitivity to cavity length detuning of the latter configuration as compared to standard mode-locking.

Summary form only given. Color image generation is an important application for amplitude modulators working in the visible spectral range. A suitable candidate is the integrated-optical Mach-Zehnder interferometer in KTP [Ruske et al. 1998]. However. Due to the very small cross section of its singlemode waveguides it can only be used for low power applications. In order to overcome this limitations, we realized a novel modulation device using large cross section waveguides with high optical damage threshold, the so called asymmetric diffraction amplitude modulator (ADAM) [Pertsch and Wachter 1999]. This device is based on a diffraction zone embedded asymmetrically between an input and an output waveguide. In the off-state the light is diffracted asymmetrically because of the reflecting boundary. At the end of the diffraction zone only a negligible fraction of light couples into the output waveguide. To switch the device to the on-state, the refractive index of a barrier region is reduced by applying a voltage to an appropriate pair of electrodes due to the electro-optical effect. This barrier creates a waveguide connecting the input and output.
只提供摘要形式。彩色图像生成是调幅器在可见光谱范围内的重要应用。一个合适的候选者是KTP的集成光学马赫-曾德尔干涉仪[Ruske et al. 1998]。然而。由于其单模波导的横截面非常小，它只能用于低功率应用。为了克服这一限制，我们实现了一种新的调制装置，使用具有高光学损伤阈值的大截面波导，即所谓的不对称衍射调制器(ADAM) [Pertsch和Wachter 1999]。该器件基于在输入和输出波导之间不对称嵌入的衍射区。在关闭状态下，由于反射边界的存在，光发生了不对称的衍射。在衍射区的末端，只有一小部分光耦合到输出波导中。为了将器件切换到导通状态，由于电光效应，通过在适当的一对电极上施加电压来降低势垒区的折射率。这个屏障创建了一个连接输入和输出的波导。

Summary form only. Recently there is a growing interest in atmospheric trace pollutants detection. One way to measure it is to use optical methods, i.e. laser absorption spectroscopy. As most of pollutants have absorption lines in the infrared region, a good way to detect them is to use a tunable infrared source with a high sensitivity detection method. The whole device we use with intracavity difference frequency generation+cavity ring down spectroscopy is a promising tool to measure atmospheric pollutants such as volatile organic compounds (VOC).

Summary form only given. We report on the fabrication of a novel dielectric T-shaped channel waveguide by liquid-phase epitaxy. Two Nd:LiYF/sub 4/ layers were grown on a LiYF/sub 4/ substrate perpendicular to each other forming the letter T in cross section. From the fabrication process, an active layer thickness of approximately 30 /spl mu/m was deduced. The whole structure was overgrown with LiYF/sub 4/. Plane parallel optical grade end faces were prepared by polishing. The LiYF/sub 4/ crystal c-axis was in the plane of the end face parallel to the vertical T-bar. Laser experiments were performed with external plane dielectric mirrors coupled directly to the waveguide end faces. Lasing of the 12.8 mm long waveguide was achieved at 1047 nm under Ti:Al/sub 2/O/sub 3/ longitudinal pumping at 792 nm. Confinement of the laser mode to the T-shaped channel could be demonstrated. However, the maximum output power of 47 mW was achieved at an incident pump power of 600 mW (50% duty cycle) only with the mode located in the vertical bar of the T slightly below the junction. Waveguide losses were estimated to be smaller than 0.8 dB/cm.

Summary form only given. We report on a Cr/sup 4+/-doped silica optical fibre, drawn from a preform prepared by modified chemical vapour deposition. The alumina-silicate core fibre contains aluminium and chromium, incorporated by the classical solution doping technique. We show that all the chromium ions present in the fibre are stabilized into the Cr/sup 4+/ oxidation state. Results on room and low temperature absorption and fluorescence are presented, and interpreted on the basis of the Tanabe-Sugano ligand-field model for transition metal ions.

Summary form only given. Recently we demonstrated the operation of an all-fibre nonlinear AND gate based on polarisation coupled gap solitons. In this system when a single pulse was incident upon the grating it was reflected irrespective of its polarisation. However when two pulses with orthogonal polarisations were incident upon the grating a coupled gap soliton was formed which was able to propagate through the grating. In addition to the AND gate we also looked at the polarisation dynamics of a single linearly polarised pulse propagating in a fibre Bragg grating. Briefly we used high nanosecond pulses obtained from a sequence of cascaded fibre amplifiers. These pulses were launched into a 8 cm apodised fibre Bragg grating and at the output light from the two orthogonal polarisations were directed onto a fibre coupled photodiode and a sampling oscilloscope with a time resolution of /spl sim/ 50 ps.

Summary form only given. Frequency stabilized lasers at 15 /spl mu/m are particularly interesting sources for modern dense-wavelength multiplexed fiber communication systems. A frequency stability of 10/sup -10/ is required for the on field devices while stability levels below 10/sup -11/ are needed for laboratory standards. The need for absolute frequency stabilization forces to use molecular or atomic references in order to achieve high stability and accuracy as well. A novel compact cavity diode pumped Er-Yb microlaser at 1.5 /spl mu/m was developed in order to overcome the long-term stability problems encountered with the previous versions of this laser source.
