摘要： A method and apparatus operates an array of laser sources as an integrated array on a single substrate or as integrated in an optical transmitter photonic integrated circuit (TxPIC) maintaining the emission wavelengths of such integrated laser sources at their targeted emission wavelengths or at least to more approximate their desired respective emission wavelengths. Wavelength changing elements may accompany the laser sources to bring about the change in their operational or emission wavelength to be corrected to or toward the desired or target emission wavelength. The wavelength changing elements may be comprise of temperature changing elements, current and voltage changing elements or bandgap changing elements. Identification tags in the form of low frequency tones may be applied relative to respective laser source outputs with a different frequency assigned to each laser source so that each laser can be specifically identified in a feedback control for providing correction signals to the wavelength changing elements to correct for the emission wavelength of respective laser sources.

摘要： An optical-to-electrical-to-optical converter comprises a monolithic receiver photonic integrated circuit (RxPIC) InP-based chip comprising an optical waveguide formed in the chip from a chip input to receive a first multiplexed channel signal from an optical link and provide them to an arrayed waveguide grating (AWG) which demultiplexes the multiplexed channel signals and provides a plurality of electrical channel signals to an electronic regenerator. The regenerator regenerates the electrical channel signals to an original signal waveform and provides the reformed electrical signals to a monolithic transmitter photonic integrated circuit (TxPIC) InP-based chip having an array of modulated sources formed in the chip that are coupled as inputs to an arrayed waveguide grating (AWG). The TxPIC modulates the reformed electrical signals to form a plurality of optical channel sign which are combined to form a second first multiplexed channel signal for transmission on an optical link.

摘要： A method of operating an array of integrated laser sources formed as an integrated array on a single substrate in a photonic integrated circuit (PIC) where the laser sources are designed for operation at different targeted emission wavelengths which, in toto, at least approximate a grid of spatial emission wavelengths. A first wavelength tuning element is associated with each laser source and is adjusted over time so that each laser source maintains its targeted emission wavelength. As an alternative, the drive current to each laser source may be initially set so that each laser source operates at its targeted emission wavelength. Thereafter, adjustments to retune the laser sources to their targeted emission wavelengths are accomplished by the first wavelength tuning elements. The outputs of the laser sources may be combined via an optical combiner to produce a single combined output from the PIC. A second wavelength tuning element is associated with the optical combiner so that the passband response or wavelength grid of the optical combiner may be also monitored and adjusted to better approximate the wavelength grid of the laser sources.

摘要： A Group III-V semiconductor optoelectronic device provides for visible wavelength light output having a more laterally uniform, high power beam profile, albeit still quasi-Gaussian. A number of factors contribute to the enhanced profile including an improvement in reducing band offset of the Group III-V deposited layers improving carrier density through a decrease in the voltage drop required to generate carrier flow; reduction of contaminants in the growth of Group III-V AlGaInP-containing layers with compositional Al, providing for quality material necessary to achieve operation at the desired visible wavelengths; the formation of an optical resonator cavity that provides, in part, weak waveguiding of the propagating light; and the utilization of a mechanism to provide for beam spreading and filing in a beam diverging gain section prior to actively aggressive gain pumping of the propagating light in the device.

摘要： A laser marking system comprises a high power fiber laser consisting of a double clad fiber having a doped core surrounded by an inner pump cladding and providing an optical output for marking; a high power laser diode source for pumping the double clad fiber laser via an input into the inner pump cladding; an optical scanner coupled to receive the marking output from the double clad fiber laser to scan the output over a surface of an article to be marked by sweeping the marking output in one, two or three dimensions to form strokes, the completion of which comprises indicia to be marked the article surface; and a controller to control the operation of the scanner in synchronism with the modulation of the laser diode pump source to initiate the marking output and sweep and modulate the marking optical output in one, two or three dimensions to form strokes comprising the indicia. A main advantage of the fiber laser marking system over CO.sub.2 and YAG laser marking systems is the ability to provide modulation via the semiconductor laser diode at the input to the marking laser rather than having to modulate the optical power beam at the output of the marking laser, such as through an acusto-optic modulator, which provides for a pulse of non-uniform stability across the pulse width with a substantially decrease in the amount of power in the modulated beam output. Also disclosed is circuitry to dampen the ON-time rise of a current signal input for operation of the laser diode pump source to improve the ON-time quality of the marking optical output created by the double clad fiber marking laser.
