Abstract

Zinc Selenide (ZnSe) infrared optical fibers 33 cm long x 1 mm in diameter have been fabricated. The measured attenuation coefficient of these fibers at 10.6 pm ranges from 0.3 dB/m to 4.0 dB/m depending on the surface quality. The minimum bend radius of a number of uncladded fibers was measured to be 73 + 8 cm. The measured transmission of uncladded fibers does not change when the fibers are bent to a radius of 115 cm. When the fibers are cladded with TFE heat shrinkable tubing, the transmission is unchanged for straight fibers. However, the attenuation of these cladded fibers increases by a factor of 1.25 when they are bent to a radius of 85 cm. The minimum bend radius of the cladded fibers is equal to that of the uncladded fibers within the uncertainty of the measurement. ZnSe can efficiently transmit radiation over a wide range of wavelengths (0.6^-14 μm). Therefore, these fibers have potential applications in catheters and endoscopes for CO₂ laser surgery, in probes for remote optical measurements of hostile environments and in various military infrared optical systems.
