Title: Improved transparent substrate light emitting diode
Inventor: LIANG BINGWEN
IPC: H01L33/46
Filed: 2001-07-25
Abstract: A gallium nitride based light emitting diode comprises both a transparent substrate (101) and a window (109) for exiting light generated by the LED.  Useful amounts of light may be utilized at the face of the window (109) or at the face of the transparent substrate (101). An external optical reflector (112) is formed directly on the external face of the LED which is not currently being used to exit useful light. If light from the window (109) is being utilized, a Distributed Bragg Reflector, or DBR, (112) is formed directly on the "backside" of the substrate. However, if light through the substrate (101) is being utilized, a DBR (112) is formed directly on the light emitting portion of the window (109).

Title: Velocity matching electrode structure for electro-optic modulators
Inventor: BETTS GARY E
IPC: G02F1/03
Filed: 2001-09-12
Abstract: This is an electro-optic modulator having an electro-optic substrate such as lithium niobate (100), an optical waveguide (200) defined within the substrate, an electrode structure including a microwave transmission line (300) elevated from the substrate by conductive legs (350A). In one embodiment, a low-dielectric constant buffer layer (400) is disposed between the substrate and the transmission line. The conductive legs extend from the transmission line to a surface of the substrate toward the wavequide, through the buffer layer. The microwave transmission line is elevated from the substrate at a distance such that the electrical propagation velocity is at a maximum. The high electrical velocity is offset by a loading capacitance introduced by the conductive legs which slows the electrical velocity down on the transmission line to match the optical velocity. Pairs of opposing conductive legs provide a strong electric filed for modulating the optical signal.

The dividing lines (13) are formed such that the width of the strip elements (11) varies along their length with the wider portions of one alongside the narrower portions of the next in a nesting action. The strips (11) are packaged for storage and transport to an end use machine where the strip elements (11) are withdrawn and cut into identical strip portions at spaced positions along the strip so that each strip portion includes a portion of minimum width and a portion of maximum width. The web (12) including all the strip elements (11) is formed into a block (10) in which the web is fan folded back and forth such that each folded portion of the web is folded relative to the next portion about a line transverse to the strip. Each strip element is continuous through the block (10) and is connected by a splice to the beginning of the next strip element. The strip has a varying width, for example, to form diaper inserts when the strip is cut into the individual strip portions. The dividing lines (13) are formed by longitudinal slits separated by un-slit bridges so that the strip elements are held together in the block and are pulled apart only when unfolded.
