| 20110235963 | FIBER-COUPLED OPTOELECTRONIC DEVICE MOUNTED ON A CIRCUIT BOARD - An optical apparatus comprises: an optical fiber, an optoelectronic device on a substrate, a circuit board, and an electrical connection therebetween. A substrate groove positions the fiber for optical coupling with the device. The substrate is mounted on the circuit board; a proximal fiber segment is secured in the substrate groove; a distal fiber segment is secured to the circuit board. The circuit board includes vias providing electrical connections between contacts on its top and bottom surfaces. A method comprises: mounting on the circuit board the substrate and optoelectronic device; establishing the electrical connection; securing proximal and distal fiber segments to the substrate groove and circuit board, respectively. Multiple substrates can be secured to a single piece of circuit board material, which can be divided into individual circuit boards after establishing electrical connections and securing optical fibers to the corresponding substrates and circuit board material. | 09-29-2011 |
| 20100024192 | OPTICAL JUNCTION APPARATUS AND METHODS EMPLOYING OPTICAL POWER TRANSVERSE-TRANSFER - A method comprises: forming an optical device on a device substrate; forming a first optical waveguide on the device or device substrate; forming a second, structurally discrete optical waveguide on a structurally discrete waveguide substrate; and assembling the optical device, first waveguide, or device substrate with the second waveguide or waveguide substrate. The device and first waveguide are arranged for transferring an optical signal between the device and the first waveguide. Upon assembly the first and second waveguides are positioned between the device and waveguide substrates and are relatively positioned for transferring the optical signal therebetween via optical transverse coupling. The first or second optical waveguide is arranged for transferring the optical signal therebetween via substantially adiabatic optical transverse coupling with the first and second waveguides so positioned. | 02-04-2010 |
| 20090304326 | ETCHED-FACET SEMICONDUCTOR OPTICAL COMPONENT WITH INTEGRATED END-COUPLED WAVEGUIDE AND METHODS OF FABRICATION AND USE THEREOF - An optical apparatus comprises: a semiconductor substrate; a semiconductor optical device integrally formed on the substrate and having an off-normal device end face; and a low-index planar optical waveguide integrally formed on the semiconductor substrate at the device end face. The device and waveguide are non-collinear, and the waveguide is end-coupled at its proximal end to the optical device by refraction at the device end face. The apparatus further includes a reflective coating between the waveguide and substrate, an etched end face curved in the horizontal dimension, or an etched end face with a lower portion that protrudes beneath a proximal portion of the waveguide. | 12-10-2009 |
