摘要： An electronic dispersion compensation (EDC) arrangement for a multi-channel optical receiver utilizes a time division technique to "share" a common adaptive algorithm block between a plurality of N separate channels. The algorithm block (40) embodies a specific algorithm associated with correcting/updating tap weights for the delay lines forming the equalizing elements, and a time slot assignment element (42) is used m conjunction with the algorithm block (40) to control the access of the various channels to the algorithm block. In situations where certain channels experience a greater degree of dispersion than others the time slot assignment element (42) may be configured to allot a greater number of time slots to the affected channels.

摘要： An SOI-based optical interconnection arrangement is provided that significantly reduces the size, complexity and power consumption requires of conventional high density electrical interconnections. In particular, a group of optical modulators and wavelength division multiplexers/demultiplexers are used in association with traditional electrical signal paths to "concentrate" a large number of the electrical-pinouts onto one optical waveguide (e.g., fiber). By utilizing a number of such SOI-based signal concentration structures, an optical backplane can be formed that couples all of these concentration structures through one optical substrate and then onto a separate number of output/receiving boards. Additionally, optical gain material may be embedded within the backplane element to further enhance the optical signal quality. The ability to integrate the electrical and optical components within a monolithic SOI-based structure provides for the significant reduction in the overall size of the connection arrangement and, further, reduces the power consumption by about an order of magnitude.

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.

摘要： An SOI-based opto-electronic structure includes various electronic components disposed with their associated optical components within a single SOI layer, forming a monolithic arrangement. EMI/EMC shielding is provided by forming a metallized outer layer on the surface of an external prism coupler that interfaces with the SOI layer, the metallized layer including transparent apertures to allow an optical signal to be coupled into and out of the SOI layer. The opposing surface of the prism coupler may also be coated with a metallic material to provide additional shielding. Further, metallic shielding plates may be formed on the SOI structure itself, overlying the locations of EMI-sensitive electronics. All of these metallic layers are ultimately coupled to an external ground plane to isolate the structure and provide the necessary shielding.

摘要： A silicon-based IR photodetector is formed within a silicon-on-insulator (SOI) structure by placing a metallic strip (preferably, a silicide) over a portion of an optical waveguide formed within a planar silicon surface layer (i.e., "planar SOI layer") of the SOI structure, the planar SOI layer comprising a thickness of less than one micron. Room temperature operation of the photodetector is accomplished as a result of the relatively low dark current associated with the SOI-based structure and the ability to use a relatively small surface area silicide strip to collect the photocurrent. The planar SOI layer may be doped, and the geometry of the silicide strip may be modified, as desired, to achieve improved results over prior art silicon-based photodetectors.

摘要： A silicon-insulator-silicon capacitive (SISCAP) optical modulator is configured to provide analog operation for applications which previously required the use of relatively large, power-consuming and expensive lithium niobate devices. An MZI- based SISCAP modulator (preferably a balanced arrangement with a SISCAP device on each arm) is responsive to an incoming RF electrical signal and is biased in a region where the capacitance of the device is essentially constant and the transform function of the MZI is linear.

摘要： A plasma-based etching process is used to specifically shape the endface of an optical substrate supporting an optical waveguide into a contoured facet which will improve coupling efficiency between the waveguide and a free space optical signal. The ability to use standard photolithographic techniques to pattern and etch the optical endface facet allows for virtually any desired facet geometry to be formed - and replicated across the surface of a wafer for the entire group of assemblies being fabricated. A lens may be etched into the endface using a properly-defined photolithographic mask, with the focal point of the lens selected with respect to the parameters of the optical waveguide and the propagating free space signal. Alternatively, an angled facet may be formed along the endface, with the angle sufficient to re-direct reflected/scattered signals away from the optical axis.

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.
