摘要： An optical system includes modulators positioned on a base. Each modulator includes a modulator waveguide that receives a light signal and guides the received light signal through the modulator. The system also includes drive electronics in electrical communication with the modulators. The drive electronics apply electrical energy to each of the modulators such that an electrical field is generated within the modulator waveguide so as to modulate one of the light signals into a modulated signal. The system includes multiple drive paths that each has a length from a contact pad on the drive electronics to a location where the electrical field is formed in one of the modulator waveguides. The modulators are configured such that the drive path length for each of the modulators is less than 0.5 mm.

摘要： The multi-channel optical device includes multiple laser cavities that each reflects a different light channel back and forth between reflective components. One of the reflective components is common to all of the laser cavities in that the common reflective component receives the channels from each of the laser cavities and reflects the received channels. The laser cavities also share a multiplexer that receives the channels reflected by the common reflective device and demultiplexes the channels into demultiplexed channels. A portion of the reflective components are partial return devices that each receives one of the demultiplexed channels. Each of the partial return devices transmits a portion of the demultiplexed channel received by that partial return device. The transmitted portion of the demultiplexed channel exits the laser cavity. Additionally, each of the partial return devices reflects a portion of the demultiplexed channel receive by that partial return device. The multiplexer also receives the transmitted portion of the channels and multiplexes the transmitted portions into an output beam.

摘要： An optical device includes a light-transmitting medium on a base. The light-transmitting medium at least partially defines a free propagation region through which light signals travel. A reflective grating is positioned such that light signals can travel through the free propagation region and be received by the optical grating. The optical grating is configured to reflect the received light signal back into the free propagation region. The optical grating reflects the light signals such that light signals associated with different wavelengths separate as the light signals travel through the free propagation region. The portion of the light-transmitting medium that defines the free propagation region has a facet through with the light signals are transmitted. The grating includes a buffer layer between the facet and a reflecting layer that is configured to reflect the light signals received by the grating.
