Abstract:
A method of cleaving a bar of optical devices into individual devices, the method comprising the steps of:a) providing a bar of optical devices, the bar defined as comprising a top surface and bottom surface;b) forming a scribe mark along said top surface at a location associated with a desired endface location for an individual optical device;c) placing a wire having a diameter less than or equal to the thickness of said bar against the bottom surface of said bar so as to be disposed underneath the location of the scribe mark formed in step b)d) exerting a force against said wire sufficient to induce stress throughout the bar and nucleate a cleavage crack under said scribe mark; ande) continuing to apply a force to allow the cleavage crack to propagate through said bar to the bottom surface, thereby separating an optical device from said bar.
