摘要： The invention relates to an electro-optic modulator structure containing an additional set of bias electrodes buried within the device for applying bias to set the operating point. Thus the RF electrodes used to modulate incoming optical signals can be operated with zero DC bias, reducing electrode corrosion by galvanic and other effects that can be present in non-hermetic packages. The bias electrodes are at least partially separated from the substrate with a buffer layer, which in one embodiment has a small amount of conductivity. This conductive buffer layer reduces optical loss from the bias electrodes and also reduces DC drift.

摘要： A method of improving device performance of optical devices formed in optical substrates is disclosed. The method requires that the optical substrate material, for example, lithium niobate, be pre-annealed to form a surface layer with a known congruent composition before diffusing the waveguide material into the substrate. It has been determined that the composition of optical substrates can vary from boule-to-boule, or even along the length of a given boule. These variations affect the diffusion rate of the waveguide material and result in varying mode sizes (both width and depth of the mode). By pre-annealing all material, the diffusion rate will remain relatively constant, regardless of the particular boule. The pre-annealing can be accomplished either by pre-equilibrating the lithium niobate in a vapor-phase equilibrating crucible containing pre-reacted lithium niobate cullet with the desired composition, or pre-equilibrating the lithium niobate to the Li.sub.2 O-rich phase boundary in a two-phase (LiNbO.sub.3, Li.sub.3 NbO.sub.4) powder bed.

摘要： The invention relates to an electro-optic modulator structure containing an additional set of bias electrodes buried within the device for applying bias to set the operating point. Thus the RF electrodes used to modulate incoming optical signals can be operated with zero DC bias, reducing electrode corrosion by electro-migration and other effects that can be present in non-hermetic packages. The bias electrodes include an upper split portion and an optically transparent lower portion. The optically transparent lower layer improves modulation frequency and reduces optical loss.

摘要： The invention relates to a wafer scale process for the manufacture of optical waveguide devices, and particularly for the manufacture of ridge waveguide devices, and the improved waveguides made thereby. The present invention has found a process for achieving sub-micron control of an optical waveguiding layer thickness by providing a dimensionally stable wafer assembly into which adhesive can be introduced without altering the planar relationship between a carrier wafer and an optically transmissive wafer in wafer scale manufacture. This process permits wafer scale manufacture of optical waveguide devices including thin optically transmissive layers. A pattern of spacer pedestals is created by a deposition and etch back, or by a surface etch process to precisely reference surface information from a master surface to a carrier wafer to a thin optically transmissive wafer. The tolerance achievable in accordance with this process provides consistent yield across the wafer.
