Abstract
A coupler is disclosed for properly positioning the endface of an optical waveguide filament with respect to an optoelectronic device in a repeatable fashion. Three elongated rods of deformable material are disposed in mutually contacting relationship within a bore which terminates at the device. After a filament is inserted into the aperture between the rods so that its endface is disposed adjacent to the device, an elastomeric washer is caused to deform inwardly against the rods, thereby causing them to engage the filament. Since the ends of the rods adjacent to the device are secured in the bore, the filament may be replaced by other filaments, the endfaces of which will be precisely positioned with respect to the optoelectronic device.
