“…There is no active components such as LED, laser diode or any sort of power supply components. We can divide the card into several major sections: (a) the POF waveguide coupler (in this design it will be a 1X4 coupler), (b) fiber positioning U-grooves [5,6], (c) short-length interconnect POF fiber (POF fiber) and (d) connectors or plugs. Another section of the POF security access-card system will be the transceiver or card reader unit.…”

An optical transceiver design for an all passive POF portable optical access-card system is presented. The portable optical access-card system includes a portable device with an optical code generating device and a transmitter/receiver system that generate the light signal and de-codes the transmitted codes. The portable optical accesscard system will utilized Plastic Optical Fiber (POF) waveguide coupler device that is embedded in the portable device itself. The optical card uses a simple coding technique of light signal transmitted from a Light Emitting Diode (LED) or laser, where the light signal is coded using a 1 X N POF waveguide coupler. The Transmitter circuit utilize simple LED circuit together and a receiving circuit using light-to-frequency converter chip.

“…It has actual and potential applications in micromechanics, metallurgy, integrated optics, electronics, optoelectronics, sensor technology and chemical engineering (Fourrier et al, 2001;Hashioka and Matsumura, 2000;Ihlemann and Rubahn, 2000;Zheng, 2006). Most of the current laser-induced manufacturing technologies, such as ultraviolet lithography, femtosecond laser processing and excimer laser fabrication (Bauer et al, 2000;Hector and Mangat, 2001;Korte et al, 2004;Lim et al, 2006;Solak et al, 1999), are based on the ablation or etching effects of substrate material caused by the high power density of the focused laser beam. These technologies have strict requirements for laser sources, including laser power, wavelength and beam quality, and may include complicated steps, like coating, masking and bonding.…”

This article reports a novel laser-induced micro-fabrication method and its monitoring system for three-dimensional (3D) microstructures. The mechanism of the method is that a small zone of thermoplastic material melted by laser heating grows in liquid surrounding environment, solidifying into a convex microstructure, such as micro-dot or micro-pillar. A laser diode (808 nm) with maximum power output of 130 mW is used as power source, and a kind of paraffin mixed with stearic acid and paint serves as the thermoplastic material for 3D microstructure formation experiments. A light microscope system consisting of a charge-coupled device (CCD) and a computer is utilized to realize real-time observation of the micro-fabricating process. The distribution of local temperature rise on material surface created by laser irradiation is simulated. The effects of liquid environment on microstructure formation have been theoretically analyzed and experimentally studied. Experiments are further carried out to investigate the relationship between laser spot and fabricated microstructures. The results indicate that the widths of micro-dots or micro-pillars are mostly determined by the size of focal spot, and their heights increase with the enlargement of laser power density. With this method, a micro-dot array of Chinese characters meaning "China" has been successfully fabricated through computer programming. This method has the advantages of implementing direct, mask-less, real-time and inexpensive 3D microstructure fabrication. Therefore, it would be widely applied in the fields of micro/nano-technology for practical fabrication of different kinds of 3D microstructures.
