“…In order to make them cater for the communication challenge, their transmittances must be greater than 95% without coating [14][15]. Fig.3 gives the transmittance of a ball lens which diameter is 1.6mm.…”

Single-mode optoelectronic communication is the technology of choice in the telecommunication industry, due to the long distances and high data rates that are achievable.These benefits are now being exploited in the field of data communications.However, the demands of the data communication application are somewhat different from those of telecommunication. This paper discusses these differences.Typical optical performance parameters for the data link are also considered.The two most important of these parameters are the laser safety limit and the minimum launched power. The methodologies which assure both of these parameters are presented.The physics of single-mode fiber-to-fiber and laser-tofiber coupling is reviewed, including an overview of various theoretical models which have been used.Results of ongoing experimental studies are presented and compared to a theoretical model.Discrepancies between the experimental results and the model are discussed.

“…Assume the beams have waist radii w,1 and wozr and the distance between the two waists is z. Since the two beams are coaxial, the coupling efficiency can then be derived by employing (2). The resultant efficiency can be expressed as where 2 1 and 2 2 are Rayleigh ranges of two beams, and are defined as Z1 = rw21/X and Z2 = 7rwi2/X, respectively.…”

“…These coupling methods can generally be divided into two groups. One group is to use discrete components as coupling optics, such as ball lenses [ 13, [2], GRIN lenses [3], cylindrical lenses [4], [5], and so on. The other is to integrate a len,s with a single-mode fiber such as hemispherical lensed fibers l [6]-[8], hyperbolic lensed fibers [9], [lo], etc.…”

A general methodl of analyzing misalignment tolerance of coupling light from an astigmatic laser diode to a single-mode fiber is described. We apply the method to derive the 3 dB tolerances caused by Ilongitudinal, lateral, and angular misalignments in the optimal coinditions for two kinds of coupling schemes. One is by the use of a rotationally symmetric optical system, and the other by a rod which is a special case of utilizing a rotationally asymmetric optical system. In the latter coupling case, the misalignment caused by a laser is found to have a much less 3 dB tolerance in the vertical direction than that caused by a fiber.
