20150229100 | METHOD FOR MANUFACTURING GALLIUM AND NITROGEN BEARING LASER DEVICES WITH IMPROVED USAGE OF SUBSTRATE MATERIAL - In an example, the present invention provides a method for manufacturing a gallium and nitrogen containing laser diode device. The method includes providing a gallium and nitrogen containing substrate having a surface region and forming epitaxial material overlying the surface region, the epitaxial material comprising an n-type cladding region, an active region comprising of at least one active layer overlying the n-type cladding region, and a p-type cladding region overlying the active layer region. The method includes patterning the epitaxial material to form a plurality of dice, each of the dice corresponding to at least one laser device, characterized by a first pitch between a pair of dice, the first pitch being less than a design width. The method includes transferring each of the plurality of dice to a carrier wafer such that each pair of dice is configured with a second pitch between each pair of dice, the second pitch being larger than the first pitch corresponding to the design width. | 08-13-2015 |

20140295595 | OPTICAL DEVICE STRUCTURE USING GaN SUBSTRATES FOR LASER APPLICATIONS - An optical device includes a gallium nitride substrate member having an m-plane nonpolar crystalline surface region characterized by an orientation of about −1 degree towards (000-1) and less than about +/−0.3 degrees towards (11-20). The device also has a laser stripe region formed overlying a portion of the m-plane nonpolar crystalline orientation surface region. In a preferred embodiment, the laser stripe region is characterized by a cavity orientation that is substantially parallel to the c-direction, the laser stripe region having a first end and a second end. The device includes a first cleaved c-face facet, which is coated, provided on the first end of the laser stripe region. The device also has a second cleaved c-face facet, which is exposed, provided on the second end of the laser stripe region. | 10-02-2014 |
