With the development of integrated optical circuits, there is a need to provide coupling of light from one optical waveguide or light source to another optical waveguide. One way of accomplishing this coupling of light is to align and secure the cleaved facet of a heterostructure diode laser (output) with the input of an optical circuit, such as an optical fiber or an optical waveguiding layer. This is a difficult task since the active layer of the laser is submerged and the optical circuit to which coupling is desired may be surface element and alignment of these two becomes very arduous.
