Paper Abstract

A non-contact optical means of accurately measuring the separation between a single-mode fiber and laser diode chip is presented along with the method to automatically set the gap separation to any pre-determined distance or to lock-in on the maximum light level. The procedure also provides a fail-safe mechanism to avoid the serious problem of running the fiber into the chip. The method will work with any size chip and any geometrically shaped fiber (from lensed to cleaved). The accuracy of the method is a function of the mechanical tolerances of the alignment machine plus the alignment of the chip with +3, -.5 micron being typical and +1, -.2 micron being state of the art.
