    Abstract: This writing discloses high-speed, single-drive and dual-drive external optical modulation devices that reduce the voltage and power required to amplify and modulate electrical signals onto an optical carrier. Two primary components of an optical transmitter (200), namely, the modulator (202) and driver (204), are integrated, and preferably hybridly integrated, in a single package, thereby eliminating many of the cable connector interfaces that add loss, complexity and cost to the system. Further, integration frees the devices from the standardized impedance (i.e. 50 ohm) constraints that reduce performance, thereby enabling the design of optimized, low voltage, hybridly integrated modulation devices.

    Abstract: The optical system comprises two optical paths (P1, P2), and an arrangement for changing the length of the two paths including two phase modulators (M1. M2) one coupled to each of the paths. A driving system (Figure 3) applies power to the phase modulators to drive them in the same direction and to change the amount of power applied to the phase modulators in opposite directions so as to change the length of each optical path in a different direction. As a result, the relationship between the changes in the amount of power applied to the modulators and the resulting changes in the phase of light beams passing through the device becomes substantially linear.

    Abstract: A silicon-based optical modulator structure includes one or more separate localized heating elements for changing the refractive index of an associated portion of the structure and thereby providing corrective adjustments to address unwanted variations in device performance. Heating is provided by thermo-optic devices such as, for example, silicon-based resistors, suicide 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 area. 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.
