A novel microlens is proposed that can be integrated on a laser-diode substrate by the planar process. A horizontal focusing lens, which is one component of this microlens, with a nearly diffraction-limited focusing spot is successfully fabricated. The relationship between fabrication errors and lens characteristics is quantitatively established by comparing lenses with various fabrication errors. Also, a laser diode integrated with the horizontal focusing lens is successfully fabricated without damage.
