Abstract: Disclosed are structures and methods directed to waveguide structures exhibiting improved device performance including improved attenuation of scattered light and/or transverse magnetic modes. In an illustrative embodiment according to the present disclosure, a rib waveguide structure including a rib overlying a slab waveguide (or superimposed thereon) is constructed wherein the slab waveguide is heavily doped at a distance from the rib which has a very low overlap with rib guided modes. Advantageously, such doping may be of the P-type or of the N-type, and dopants could be any of a number of known ones including—but not limited to—boron, phosphorous, etc.—or others that increase optical propagation loss. As may be appreciated, the doped regions advantageously absorb scattered light which substantially improves the structure's performance.Alternative illustrative embodiments of structures according to the present disclosure will include a metal deposited upon the slab waveguide at a distance from the rib such that scattered light is absorbed and the structure's performance is likewise enhanced.

Abstract: Disclosed herein are methods, structures, apparatus and devices that improve the control and/or controllability of a group of Mach-Zehnder Interferometer modulators. Advantageously, such control may be implemented with optical tuning elements shared among all of the modulators, or with separate optical tuning elements operated through the effect of a set of common signals. Accordingly implementations according to one aspect of the present disclosure provides a significantly simplified configuration—where the extinction ratios of all modulators within the group are controlled jointly—in sharp contrast to those configuration(s) wherein all modulators are individually controlled.

Abstract: Disclosed are designs and methods of fabrication of silicon carrier-depletion based electro-optical modulators having doping configurations that produce modulators exhibiting desirable modulation efficiency, optical absorption loss and bandwidth characteristics.
