Optical fibers, plastic

Generally, these exists a tradeoff between speed and output power in these devices. The data for fiber-coupled devices are based on emission into a 50/125-//m fiber, except for AlGalnP which is for 1-mm plastic optical fiber coupling. 

Optics. Good optical properties and low thermal resistance make poly(methyl methacrylate) polymers well suited for use as plastic optical fibers. The manufacturing methods and optical properties of the fibers have been reviewed (124) (see Fiber optics). Methods for the preparation of Fresnel lenses and a Fresnel lens film have been reported (125,126). Compositions and methods for the industrial production of cast plastic eyeglass lenses are available (127). 

Recently, optical telecommunications tliat transmit large amounts of information via light signals have been rapidly replacing conventional electrical telecommunications. Optical polymers, such as poly(methylmethacrylate) (PMMA), polystyrene (PS), and polycarbonate (PC) are used for plastic optical fibers and waveguides. However, these polymers do not have enough Ihermal... 

Sensors incorporating glass or plastic optical fibers have demonstrated several advantages over electrosensors for biomedical applications. These sensors involve no electrical connections and hence are safe from that standpoint the leads are quite small and flexible they can be incorporated in catheters for multiple sensing where required, they can be implanted for relatively long periods. The fibers are considerably less than 1 millimeter in diameter. Where designed for simplicity, they often can be considered disposable.

RCLEDs are now commercial products that are manufactured by the millions per year. Primary applications are in signage and communication. The devices are particularly well suited for plastic optical fiber systems. The directed emission pattern improves LED-fiber coupling efficiency The narrow emission line reduces material and chromatic dispersion effects. As a result, RCLEDs enable longer transmission distances and simultaneously higher data rates.

Japan s Mitsubishi Rayon Co. Ltd. Developed a plastic optical fiber cable Eska Premium with a wide range of freedom, excellent durability and which can be used for wiring in narrow spaces. It is claimed that the cable can be bent or wound without deteriorating the characteristics of the fiber cable. The cable is lighter and easier to work with than glass-based cables, and is ideal for short communications and transmission wiring between the controllers of machine tools, personal computers, and peripheral equipment.

Further development of the pH probe for practical use was continued by Markle and colleagues [21]. They designed the fiber optic probe in the form of a 25-gauge (0.5 mm OD) hypodermic needle, with an ion-permeable side window, using 75-p.m-diameter plastic optical fibers. The sensor had a 90% response time of 30 s. With improved instrumentation and computerized signal processing and with a three-point calibration, the range was extended to 3 pH units, and a precision of 0.001 pH units was achieved.
