Abstract:
1. A device for aligning an optical fiber with an output facet of a laser diode to obtain a substantially optimum coupling efficiency, said device comprising: a universal joint through which said optical fiber passes such that an end of said optical fiber is adjacent to said output facet of said laser diode; and an adjustment means located at a distance from said universal joint such that displacement of said adjustment means causes a pivotal movement of said optical fiber about a pivotal point of said universal joint and results in a smaller displacement of said end of said optical fiber, wherein said universal joint comprises a ball, having an aperture through a centre for receiving said optical fiber, a mount housing said ball, and biasing means for biasing said ball into an internal conical socket within said mount, said socket having an aperture through which said optical fiber protrudes.
