摘要： A unitary optical receiver assembly is formed to include a V-groove passively aligned with a first aspheric lens (the lens formed along a surface perpendicular to the V-groove). An optical fiber is disposed along the V-groove and is used to bring the received optical signal into the unitary assembly. Upon passing through the first aspheric lens, the received optical signal will intercept a 45° turning mirror wall that directs the signal downward, through a second aspheric lens (also molded in the unitary assembly), and then into a photosensitive device. Advantageously, the photosensitive device is disposed in passive alignment with the second aspheric lens, allowing for a received signal to be coupled from an incoming optical fiber to a photosensitive device without needing any type of active alignment therebetween.

摘要： A silicon-on-insulator (SOI)-based tunable laser is formed to include the gain medium (such as a semiconductor optical amplifier) disposed within a cavity formed within the SOI substrate. A tunable wavelength reflecting element and associated phase matching element are formed on the surface of the SOI structure, with optical waveguides formed in the surface SOI layer providing the communication between these components. The tunable wavelength element is controlled to adjust the optical wavelength. Separate discrete lensing elements may be disposed in the cavity with the gain medium, providing efficient coupling of the optical signal into the SOI waveguides. Alternatively, the gain medium itself may be formed to include spot converting tapers on its endfaces, the tapers used to provide mode matching into the associated optical waveguides.

摘要： The surface silicon layer (SOI layer) of an SOI-based optical modulator is processed to exhibit a corrugated surface along the direction of optical signal propagation. The required dielectric layer (i.e., relatively thin “gate oxide”) is formed over the corrugated structure in a manner that preserves the corrugated topology. A second silicon layer, required to form the modulator structure, is then formed over the gate oxide in a manner that follows the corrugated topology, where the overlapping portion of the corrugated SOI layer, gate oxide and second silicon layer defines the active region of the modulator. The utilization of the corrugated active region increases the area over which optical field intensity will overlap with the free carrier modulation region, improving the modulator's efficiency.

摘要： An optical modulator is formed to include a plurality of separate electrodes disposed along one arm, the electrodes having different lengths and driven with different signals to provide for multi-level signaling (e.g., PAM-4 signaling). By using separate drivers to energize the different sections, the number of sections energized at a given point in time will define the net phase shift introduced to the optical signal. The total length of the combined modulator sections is associated with a π phase shift (180°). Each section is driven by either a digital “one” or “zero”, so as to create the multi-level modulation. An essentially equal change in power between adjacent transmitted symbols is accomplished by properly adjusting the lengths of each individual section.

摘要： A semiconductor-based optical modulator is presented that includes a separate phase control section to adjust the amount of chirp present in the modulated output signal. At least one section is added to the modulator configuration and driven to create a pure “phase” signal that will is added to the output signal and modify the eiφ term inherent in the modulation function. The phase modulation control section may be located within the modulator itself (with one segment on each arm, driven by the same input signal), or may be disposed “outside” of the modulator on either the input waveguiding section or the output waveguiding section. The phase control section may be formed to comprise multiple segments (of different lengths), with the overall phase added to the propagating signal controlled by selecting the different segments to be energized to impart a phase delay to a signal propagating through the energized section(s).

摘要： A planar, waveguide-based silicon Schottky barrier photodetector includes a third terminal in the form of a field plate to improve the responsivity of the detector. Preferably, a silicide used for the detection region is formed during a processing step where other silicide contact regions are being formed. The field plate is preferably formed as part of the first or second layer of CMOS metallization and is controlled by an applied voltage to modify the electric field in the vicinity of the detector's silicide layer. By modifying the electric field, the responsivity of the device is “tuned” so as to adjust the momentum of “hot” carriers (electrons or holes, depending on the conductivity of the silicon) with respect to the Schottky barrier of the device. The applied potential functions to align with the direction of momentum of the “hot” carriers in the preferred direction “normal” to the silicon-silicide interface, allowing for an increased number to move over the Schottky barrier and add to the generated photocurrent.

摘要： An arrangement for improving adhesive attachment of micro-components in an assembly utilizes a plurality of parallel-disposed slots formed in the top surface of the substrate used to support the micro-components. The slots are used to control the flow and “shape” of an adhesive “dot” so as to quickly and accurately attach a micro-component to the surface of a substrate. The slots are formed (preferably, etched) in the surface of the substrate in a manner that lends itself to reproducible accuracy from one substrate to another. Other slots (“channels”) may be formed in conjunction with the bonding slots so that extraneous adhesive material will flow into these channels and not spread into unwanted areas.

摘要： An arrangement for providing optical crossovers between waveguides formed in an SOI-based structure utilize a patterned geometry in the SOI structure that is selected to reduce the effects of crosstalk in the area where the signals overlap. Preferably, the optical signals are fixed to propagate along orthogonal directions (or are of different wavelengths) to minimize the effects of crosstalk. The geometry of the SOI structure is patterned to include predetermined tapers and/or reflecting surfaces to direct/shape the propagating optical signals. The patterned waveguide regions within the optical crossover region may be formed to include overlying polysilicon segments to further shape the propagating beams and improve the coupling efficiency of the crossover arrangement.
