英文摘要	To position a light output device such as a laser diode relative to a light device such as a waveguide so as to obtain maximum coupling of light, the waveguide end facing the laser is vibrated by mechanical means to modulate the coupled light. Light is detected from a remote end of the fiber and a corresponding electrical signal is generated. Positional information contained in the oscillatory component of the signal is decoded and applied to a positioning device which then reduces misalignment between the waveguide and laser. The positioning device continuously seeks the maximum coupling position. The technique finds particular application in positioning a waveguide in a laser package prior to and during anchoring.
