摘要： A method of forming thin film waveguide regions in lithium niobate uses an ion implant process to create an etch stop at a predetermined distance below the lithium niobate surface. Subsequent to the ion implantation, a heat treatment process is used to modify the etch rate of the implanted layer to be in the range of about 20 times slower than the bulk lithium niobate material. A conventional etch process (such as a wet chemical etch) can then be used to remove the virgin substrate material and will naturally stop when the implanted material is reached. By driving the ions only a shallow distance into the substrate, a backside etch can be used to remove most of the lithium niobate material and thus form an extremely thin film waveguide that is defined by the depth of the ion implant. Other structural features (e.g., ridge waveguides) may also be formed using this method.

摘要： A Mach-Zehnder electro-optic modulator is formed that exhibits significantly reduced chirp by utilizing an RF electrode that covers a first waveguide arm in a first region of the modulator and covers the second, remaining waveguide arm in a third region of the modulator (with a second, intermediate region used as a transition area for the electrode). Moving the electrode from one waveguide to the other allows for the chirp created in the third region to essentially “null out” the chirp that accumulated along the first region. Modulation of the optical signal is maintained in the presence of the “electrode switching” by inverting the domain of the optical substrate material in the third region of the modulator.

摘要： A method and system perform physiological monitoring. The system includes a first light source and a plurality of optical waveguide couplers, each of the plurality of optical waveguide couplers being arranged at a different predetermined spatial location on an ocular insert to be placed on an eye. The system also includes a plurality of optical waveguides. Each optical waveguide carries light from a second light source to a respective one of the plurality of optical waveguide couplers and carries a received signal from the respective one of the plurality of optical waveguide couplers. A processor receives the received signal from each of the plurality of optical waveguides and monitors a parameter based on the received signal.

In one embodiment, the MZM includes an MZM drive circuit coupled to the electrodes and configured to deliver to the electrode a DPSK drive signal bearing digital data and having a voltage that exceeds a normal drive voltage of the MZM by at least about 20%.

摘要： The specification describes an optical modulator implemented with an MSK format. The modulator creates two separate pulse streams (one pulse stream comprising the odd bits and the other comprising the even bits of the data stream) using a 1-by-2 pulse generator. The modulator then uses electrooptic phase modulators to encode the odd and even numbered bits separately, and a 50/50 coupler to remix them.
