An optical time domain ref lectometer (OTDR) and its components are described in detail. The system performance for this device is examined. Experimental methods are described for the measurement of several parameters of interest in the characterization of optical fibers usinq the OTOR. These parameters include scatterinq loss and capture fractions for unperturbed fibers. Experimental capture-fraction values are reported for several step and qraded-index fibers and these results are compared with theoretical predictions. Rayleiqh backscatter siqnatures are also presented for several fibers from different manufacturers. Fault signatures are shown for some intrinsic and extrinsic fiber perturbations.

“…Outputs of over 3 W were recently reported using mixed gases of argon and krypton [ 31. Such power levels are s t i l l far below the power handling capability of glass optical fibers [4]. In applications where black-and-white displays are adequate, a very inexpensive He-Ne laser can be utilized effectively to obtain "V or photographic displays.…”

By overcoating Si0 thin film at the sub strate temperature of about 30O0C, the oh of InSb thin f i i decreased to 93 pmho and the gain was improved.The sample without overcoating by Si0 thin film in Fig. 4 has a very mall value of oh = 8.7 pmho, and indicates only interaction between a hole carrier and the elastic surface wave. The oh increases in 16.5 pmho by overcoating Si0 thin f h at around 95"C, and the device shows interaction between an electron carrier and surface wave.In conclusion, we have shown that the effect of overcoating Si0 thin tilms at various temperatures can be useful in producing monolithic elastic surface-wave amplifiers, although we cannot yet fully explain this phenomenon physically.
