摘要： A co-planar waveguide interferometric electro-optic modulator that reduces the bias point sensitivity of the modulator to ambient temperature and to applied RF is described. The modulator includes a first and second waveguide that are formed in an electro-optic substrate. A RF electrode is positioned on the electro-optic substrate between the first and the second waveguide. A ground electrode that may include a slot is positioned proximate to the second waveguide. A guard ground electrode is positioned proximate to the first waveguide to sink heat from the RF electrode and may also balance the thermal stress in the two waveguides. A dielectric material may also be positioned proximate to the first waveguide to balance the thermal stress in the two waveguides.

摘要： An optical pulse generator having a high order transfer function that comprises a first and a second nested interferometric modulator, each modulator comprising an optical input, an electrical input, a first arm, a second arm and an optical output. The second interferometric modulator is optically coupled into the second arm of the first interferometric modulator. The optical output of the first interferometric modulator generates pulses at a repetition rate that is proportional to a multiple of a frequency of an electrical signal applied to the electrical input of at least one of the first and second interferometric modulator and at a duty cycle that is inversely proportional to the order of the transfer function of the optical pulse generator. The multiple may be any integer equal to or greater than one.

摘要： An electro-optic device including an optical waveguide formed in an electro-optic material that propagates an optical signal along a first direction of propagation is described. The device also includes an electrical waveguide formed in the electro-optic material and positioned co-linear relative to the optical waveguide and in electromagnetic communication with the optical waveguide, where the electrical waveguide also propagates the electrical signal in the first direction of propagation. A compensation network is electrically coupled to the electrical waveguide at a junction and propagates the electrical signal in a second direction of propagation that is substantially non-co-linear with the first direction of propagation. In operation, the compensation network modifies at least one of a phase or an amplitude of the electrical signal at the junction relative to a phase or an amplitude of the accumulated modulation on the optical signal at the junction, respectively, and then returns the modified electrical signal to the electrical waveguide.

摘要： Method and apparatus are disclosed for the stable control of electrooptic devices, such as for providing a stable bias point for operation of a lithium niobate interferometer-type modulator. The bias point of the modulator is thermally controlled by providing a selected difference in the temperatures of optical waveguide lengths of the interferometer. Heaters can be disposed with the lithium niobate substrate for transferring thermal energy with the optical waveguide lengths. A thermally conductive element can be disposed adjacent the optical waveguide lengths to act as “heat spreaders” to facilitate providing the selected difference in temperature. The invention also includes phase shifters, attenuators, and other optical devices formed from single and multiple optical waveguide lengths propagating separate optical beams.

摘要： An optical external modulator includes an optical waveguide having a first interferometer section and a second interferometer section formed on an electro-optic substrate. An electrode structure disposed on the substrate transmits an RF drive signal that is applied to the first and second interferometer sections in series. A reflector optically coupled to the substrate redirects light away from the first interferometer section to the second interferometer section and provides an optical fold region that introduces an optical time delay between the first and second interferometer sections. The optical time delay is used for at least partially compensating for a velocity mismatch between the light and the RF drive signal.

摘要： An optical digital external modulator having a cascaded arrangement of interferometers is provided. The optical modulator includes an electrode structure for applying an electric field to each interferometer in the cascade and biasing circuitry coupled to the electrode structure for biasing each interferometer at a predetermined bias point. In particular, each predetermined bias point is selected to be above quadrature and for providing improved transmission performance of digital data signals. Preferably, the modulator has a reflective design that helps to increase the modulation bandwidth, lower the drive voltage, and reduce size.

摘要： An electrical termination circuit for a traveling wave optoelectronic device is disclosed. The electrical termination circuit is constructed to reflect a portion of a radio-frequency signal back into the optoelectronic device. The reflected signal is out of phase with the applied radio-frequency signal at a frequency of a detrimental spectral feature or a bump in an electro-optical transfer characteristic of the optoelectronic device. The amplitude and the phase of the reflected signal are selected so as to suppress the detrimental spectral feature without a significant reduction in the efficiency of electro-optical or optical-electrical transformation of the optoelectronic device.

摘要： A method of controlling the operating parameters of an optical modulator, without using a dither signal, is provided. Past operating parameters are compared to present operating parameters using a quality of modulation signal obtained by cross-correlating the data modulation signal used to drive the optical modulator with the modulated optical signal output from the optical modulator. The quality of modulation signal is used to optimize the operating parameters (e.g., bias point) of the optical modulator, or other operating parameters of the arrangement, such as the modulator drive level, timing alignment, etc.
