    Abstract: A silicon-based optical modulator structure (20) includes one or more separate localized heating elements (22/24) for changing the refractive index of an associated portion of the structure and thereby providing corrective adjustments to address unwanted variations i device performance Heating is provided by thermo-optic devices such as, for example, silicon- based resistors, silicide resistors, forward-biased PN junctions, and the like, where any of these structures may easily be incorporated with a silicon-based optical modulator The application of a DC voltage to any of these structures will generate heat, which then transfers into the waveguiding are The increase in local temperature of the waveguiding area will, in turn, increase the refractive index of the waveguiding in the area Control of the applied DC voltage results in controlling the refractive index

    Abstract: 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.

    Abstract: An arrangement for providing optical coupling into and out of a relatively thin silicon waveguide formed in the SOI layer of an SOI structure includes a lensing element and a defined reference surface within the SOI structure for providing optical coupling in an efficient manner. The input to the waveguide may come from an optical fiber or an optical transmitting device (laser).

    Abstract: An optical modulator is formed to include an adjustable drive arrangement for dynamically adjusting the effective length of the optical signals path(s) within the modulator. Each modulator arm is partitioned into a plurality of segments, with each segment coupled to a separate electrical signal driver. Therefore, the effective length of each modulator arm will be a function of the number of drivers that are activated for each arm at any given point in time. A feedback arrangement may be used with the plurality of drivers to dynamically adjust the operation of the modulator by measuring the extinction ratio as a function of optical power, turning "on" or "off" individual drivers accordingly.

    Abstract: A wafer-level testing arrangement for opto-electronic devices formed in a silicon-on-insulator (SOI) wafer structure utilizes a single opto-electronic testing element to perform both optical and electrical testing. Beam steering optics may be formed on the testing element and used to facilitate the coupling between optical probe signals and optical coupling elements (e.g., prism couplers, gratings) formed on the top surface of the SOI structure. The optical test signals are thereafter directed into optical waveguides formed in the top layer of the SOI structure. The opto­electronic testing element also comprises a plurality of electrical test pins that are positioned to contact a plurality of bondpad test sites on the opto-electronic device and perform electrical testing operations. The optical test signal results may be converted into electrical representations within the SOI structure and thus returned to the testing element as electrical signals.

    Abstract: A planar optical isolator is formed within the silicon surface layer of an SOI structure. A forward-directed signal is applied to an input waveguiding section of the isolator and thereafter propagates through a non-reciprocal waveguide coupling region into an output waveguide section. A rearward-directed signal enters via the output waveguide section and is thereafter coupled into the non-reciprocal waveguide structure, where the geometry of the structure functions to couple only a small amount of the reflected signal into the input waveguide section. In one embodiment, the non-reciprocal structure comprises an N-way directional coupler (with one output waveguide, one input waveguide and N-1 isolating waveguides). In another embodiment, the non-reciprocal structure comprises a waveguide expansion region including a tapered, mode-matching portion coupled to the output waveguide and an enlarged, non-mode matching portion coupled to the input waveguide such that a majority of a reflected signal will be mismatched with respect to the input waveguide section. By cascading a number of such planar SOI-based structures, increased isolation can be achieved - advantageously within a monolithic arrangement.

    Abstract: An arrangement for achieving and maintaining high efficiency coupling of light between a multi-wavelength optical signal and a relatively thin (e.g., sub-micron) silicon optical waveguide uses a prism coupler in association with an evanescent coupling layer. A grating structure having a period less than the wavelengths of transmission is formed in the coupling region (either formed in the silicon waveguide, evanescent coupling layer, prism coupler, or any combination thereof) so as to increase the effective refractive index "seen" by the multi -wavelength optical signal in the area where the beam exiting/entering the prism coupler intercepts the waveguide surface (referred to as the "prism coupling surface"). The period and/or duty cycle of the grating can be controlled to modify the effective refractive index profile in the direction away from the coupling region so as to reduce the effective refractive index from the relatively high value useful in multiwavelength coupling to the lower value associated with maintaining confinement of the optical signals within the surface waveguide structure, thus reducing reflections along the transition region.
