    摘要： A package for an optoelectronic device includes a hermetically sealed cavity into which a mirror or other optical element is integrated. For a side-emitting laser, an integrated mirror turns the light emitted from the laser inside the cavity so that the light exits through a top surface of the package. The packaging can be implemented for individual lasers or at the wafer level. A wafer level process fabricates sub-mounts in a first wafer, fabricates depressions with reflective areas in a second wafer, electrically connects optoelectronic devices to respective sub-mounts on the first wafer, and bonds a second wafer to the first wafer with the lasers hermetically sealed in cavities corresponding to the depressions in the second wafer. The reflective areas in the depressions act as turning mirrors for side emitting lasers.

    摘要： A system is described for interconnecting a first optical component and a second optical component in which the first optical component is guided passively into precise alignment with the second optical component. The system includes a base and a guide structure. The base has a first surface exposed for contact with a front surface of the first optical component and a second surface configured to contact a front surface of the second optical component, and defines a transparent optical aperture extending from the first base surface to the second base surface and aligned with respect to the optical axis. The guide structure is supported by the base in fixed registration with respect to the optical axis and is exposed for contact with an exposed peripheral surface of the first optical component at three or more spaced apart discrete locations. The passive alignment system may be used with a wide variety of different optical connectors, including connectors implemented in accordance with existing optical connection standards, without the need for proprietary interlocking features or special modification.

    摘要： A scheme (systems and methods) for passively aligning one or more optical devices with a corresponding number of optical lenses in an accurate and efficient manner is described. By this approach, the invention avoids the often labor-intensive and costly steps required by conventional active alignment techniques that attempt to align the optical devices to the optical fibers. In one aspect, an optoelectronic device includes an optical device system, an optical lens system and a plurality of solder bumps disposed therebetween. The optical device system includes an optical device substrate supporting one or more optical devices and a solderable metallization pattern having a spatial arrangement with respect to the one or more optical devices. The optical lens system includes one or more optical lenses and a device bonding surface supporting a solderable metallization pattern having a spatial arrangement with respect to the one or more optical lenses. The solder bumps are disposed between the metallization patterns of the optical device system and the optical lens system. The plurality of solder bumps bond the optical device substrate to the device bonding surface with the one or more optical devices aligned with the one or more optical lenses. In another aspect, the optical lens system includes a spacer substrate defining one or more apertures therethrough. A method of aligning an optical device system and an optical lens system also is described.

    摘要： An interpolation circuit for an optical encoder or other sensing device includes a signal generating circuit, a comparator circuit and a logic circuit. The signal generating circuit generates A, A′, B, B′, one or more fractional A or A′ and one or more fractional B or B′ ramp signals in response to input ramp signals that are one quarter cycle out of phase. The comparator circuit compares selected pairs of the A, A′, B, B′, one or more fractional A or A′ and one or more fractional B or B′ ramp signals and generates intermediate signals. The phases of the intermediate signals are preferably uniformly or nearly uniformly distributed in phase with respect to the ramp signals. The logic circuit combines the intermediate signals and provides first and second output signals, each having multiple cycles of the ramp signals. In one embodiment, the signal generating circuit generates A, A′, B, B′, A/3 or A′/3 and B/3 or B′/3 ramp signals. The logic circuit provides first and second output signals having a total of 16 states, thereby providing a resolution of 16 states for each cycle of the ramp signals.
