摘要： A semiconductor laser source includes a partial-grating DFB laser with two laser electrodes, one over the grating and the other between the grating and one end of the laser. Constant laser currents flow into the waveguide through the electrodes (typically different from each other) and produce laser output. A wavelength discriminator, an optical detector, and a wavelength-control circuit act as a wavelength-control feedback mechanism to generate a wavelength control current that flows through one laser electrode or the other, or through both electrodes with opposite polarities. Phase noise on the laser output can be reduced at modulation frequencies exceeding several hundred kHz up to one or several tens of MHz or more. The laser-wavelength can be swept while exhibiting reduced phase noise.

摘要： A method of fabricating a semiconductor laser device by forming a semiconductor structure at least part of which is in the form of a mesa structure having a flat top. The steps include depositing a passivation layer over the mesa structure, forming a contact opening in the passivation layer on the flat top of the mesa structure; and depositing a metal contact portion, with the deposited metal contact portion contacting the semiconductor structure via the contact opening. The contact opening formed through the passivation layer has a smaller area than the flat top of the mesa structure to allow for wider tolerances in alignment accuracy. The metal contact portion comprises a platinum layer between one or more gold layers to provide an effective barrier against Au diffusion into the semiconductor material.

摘要： An optical transmitter for generating a modulated optical signal to be transmitted over fiber optical link. The transmitter includes: an optical source for producing an optical signal; an optically linearized modulator (OLM) as external modulator for modulating the optical signal produced by the optical source with an information carrying signal. The external modulator includes a first input port for receiving a first DC bias signal, and a second input port for receiving a second DC bias signal. The optical transmitter further includes a pilot tone generator for generating a first pilot signal to be applied to the first input port and a second pilot signal to be applied to the second input port. The first and second pilot signals are capable of producing distortion products in the modulated optical signal. A differential modulation signal is imposed onto either the first pilot signal or the second pilot signal so as to generate a first control signal that alternately adjusts the first DC bias signal and the second DC bias signal in order to minimize the distortion products. The optical transmitter may include a digital based control system that is adapted to reduce composite even and odd order distortions in the OLM.

摘要： A multimode interference splitter/combiner that includes a monolithic device for photonically coupling an input optical waveguide to first and second output optical waveguides. The input waveguide may be optically coupled to a first end of a MMI portion, while the first and second output waveguides may be optically coupled to a second end of the MMI portion. The input waveguide is coupled to a planar facet of the MMI portion so that the input waveguide may have a propagation axis that is oriented at an angle with respect to the planar facet of the MMI portion. A desired splitting ratio may be achieved by adjusting the angle between the input waveguide and the MMI portion.
