Selective optical excitation permits both the group index and the group delay of on-axis modes of multimode fibers to be determined with high precision. The group index of several types of fiber was measured at 1310 nm in a fiber Michelson interferom

We describe a new type of optical reflectometry which is useful in testing single-mode lightguide systems. This technique uses a scanning Michelson interferometer in conjunction with a broadband illuminating source and cross-correlation detection. Hi

Calibration of optical time domain reflectometers by military and industrial users can be achieved by a number of published test procedures. For some performance parameters, a particularly convenient method for establishing measurement verification a

Laser diode waveguides are probed using low coherence optical reflectometry. Reflections from the launch optics, front facet, and rear facet are located with a resolution of approximately 10 micrometers . Diodes mounted in pigtailed packages and on c

We describe a method for measuring submicrometer distances with an asymmetric fiber Michelson interferometer having an LED as a source of radiation. By measuring the phase slope of the Fourier components in the frequency domain, it is possible to loc

Several optical properties of a concentric-core fiber are examined. These include attenuation, radiation patterns, pulse broadening, index profile, backscatter signatures, and capture fraction. Experimental techniques are briefly described, and the s

The frequency and wavelength of the methane-stabilized laser at 3.39 \ensuremath{\mu}m were directly measured against the respective primary standards. With infrared frequency synthesis techniques, we obtain $\ensuremath{\nu}=88.376181627(50)$ THz. W

The frequencies of three lasers stabilized to molecular absorptions were measured with an infrared‐frequency synthesis chain extending upwards from the cesium frequency standard. The measured values are 29.442 483 315 (25) THz for the 10.18‐μm R
