摘要： An electro-optic modulator imparts the information contained in an electrical signal traveling along a transmission line onto an optical carrier by using signal-related variations in the electrical signal's voltage to modulate the refractive index or absorption in an electro-optic material through which the optical carrier propagates. For optimal bandwidth and modulation efficiency, the microwave and optical waves should be matched in velocity. However, conventional microwave transmission lines have a microwave velocity that is somewhat higher than the optical group velocity in typical optical waveguides. Tuning a microwave transmission line's capacitance reduces the microwave velocity, but also reduces the impedance below the 50 Ω impedance of most microwave components. Conversely, tuning the microwave transmission line's inductance makes it possible to match the microwave velocity to the optical group velocity over bandwidths of 100 GHz or greater while maintaining a microwave impedance of 50 Ω.

摘要： A slab-coupled optical waveguide laser (SCOWL) is provided that includes an upper and lower waveguide region for guiding a laser mode. The upper waveguide region is positioned in the interior regions of the SCOWL. The lower waveguide region also guides the laser mode. The lower waveguide region is positioned in an area underneath the upper waveguide region. An active region is positioned between the upper waveguide region and the lower waveguide region. The active region is arranged so etching into the SCOWL is permitted to define one or more ridge structures leaving the active region unetched.

摘要： A very large mode (VLM) slab-coupled optical waveguide laser (SCOWL) is provided that includes an upper waveguide region as part of the waveguide for guiding the laser mode. The upper waveguide region is positioned in the interior regions of the VLM SCOWL. A lower waveguide region also is part of the waveguide that guides the laser mode. The lower waveguide region is positioned in an area underneath the upper waveguide region. An active region is positioned between the upper waveguide region and the lower waveguide region. The active region is arranged so etching into the VLM SCOWL is permitted to define one or more ridge structures leaving the active region unetched. One or more mode control barrier layers are positioned between said upper waveguide region and said lower waveguide region. The one or more mode control barrier layers control the fundamental mode profile and prevent mode collapse of the laser mode. The mode control barrier layers also block carrier leakage from the active region. These layers are essential to obtaining VLM SCO WLs.

摘要： An electro-optic push-pull modulator requiring reduced high switching voltages through combinations of device structure and operation, causing linear and quadratic electro-optic effects to add. Such combinations of device structure and operation include combinations of crystal axis orientation, waveguide structure, electrode structure, electric field biasing, operating wavelengths, and optical polarizations. By inducing linear and quadratic electro-optic effects to add, significant refractive index changes can be realized with lower switching voltages, V pi . Furthermore, significant reduction in switching voltage for push-pull modulators can also be realized through combinations of device structure and operation effectively inducing solely the quadratic electro-optic effect.

摘要： A laser and optical amplifier waveguide device with a plurality of layers that supports a single lowest-order optical mode with gain while higher order nodes radiate and have a net loss. The supported lowest-order mode which has gain, has a mode cross section which is large compared to the operating optical wavelength in both the transverse and lateral directions. The contours of constant optical intensity of such lowest-order can be nearly circular, having an approximately elliptical shape with a small aspect ratio.
