INTRODUCTION
... The choice of wavelength depends upon the loss profile of the medium. For optical fiber the wavelength has to be 1300nm or 1550nm for low loss. The spectral width has direct bearing on the data rate which the medium can support. Larger the spectral width, smaller is the data rate. A semiconductor la ...

Hollow Retroreflectors Promote Precision Optical Alignment
... When a beam enters a retroreflector, it creates an optical path with a total length defined by three bounces. This path depends on the location of the incoming beam with respect to the apex of the device. To better understand the process, it helps to examine an idealized situation with only two boun ...
