Abstract
Alignment is established between a member that defines an optical path and a semiconductor device that, when electrically biased, emits light in a predetermined direction, so as to establish an optically coupled relationship between the member and the device, by passing light along the optical path in a direction towards the semiconductor device, so that light is incident on the semiconductor device. An electrical characteristic of the semiconductor device is observed, and relative movement between the member and the device is brought about until the electrical characteristic indicates a desired degree of optical coupling between the member and the device, and the device and the member are then mechanically coupled together.
