| A novel device and method of beam steering for semiconductor lasers or optical amplifiers is disclosed. The method of the present invention achieves high signal extinction ratios, high speed, low chirp modulation by biasing a multi-lateral mode beam steering section. The device of the present invention comprises an active single vertical and lateral mode optical waveguide, a multi-lateral mode waveguide, and a mode converter. The mode converter efficiently couples output from an active single mode waveguide to two or more modes of a multi-lateral mode waveguide. Two guided modes arrive at a device facet with a particular intermodal phase difference based on initial mode phasing, multi-lateral mode waveguide length and modal dispersion properties, and facet angle. Beam steering is achieved through carrier antiguiding effect by injecting current into the multi-lateral mode waveguide from the mode converter thus changing the intermodal dispersion. Changing the intermodal phase difference changes the direction of beam propagation relative to the device facet, providing enhanced beam steering. | ||||||

| When an output instruction is input to a control unit, the control unit controls a seed laser light source and a pumping light source to be either in a pre-pumped state or in an output state. In the pre-pumped state, the pumping light source outputs, for a predetermined period, pumping light with an intensity determined based on the duration of the period of time from when the output state prior to the input of the output instruction to the control unit comes to an end till when the output instruction is input to the control unit. In the output state, to cause the output unit to output laser light, the seed laser light source outputs laser light, and the pumping light source outputs pumping light. | ||||||

| A device for use in optical signal control is presented. The device comprises an amplification waveguide, including a pumpable medium, and a reference and a control inputs and an output selectively allowing transmission of light respectively into and out of said amplification waveguide. The reference input, the amplification waveguide and the output define together a transmission scheme for reference light through the pumpable medium. The control input and the amplification waveguide define a depletion scheme for the pumpable medium and control light. The device thus allows for controlling an output signal, formed by the transmission of the reference light, by controllable depletion of the pumpable medium. | ||||||

| A gain equalizer in which a multichannel input light signal is split into its separate wavelength components by means of a dispersive element such as a grating, and the spatially separated wavelength components are passed through a linear array of variable optical attenuators based on liquid crystal phase elements which modulate the phase of part of the cross section of the light. The separate attenuated wavelength components are then recombined and output. The attenuation level of each variable optical attenuator is adjusted according to the output of the light as a function of its wavelength components, and in this way, the overall wavelength profile of the output light signal can be adjusted to any predefined form, whether a flattened spectral profile, as in gain equalization applications, or a spectral compensating profile. | ||||||

| A fiber optical attenuator utilizing the cut-off phenomenon for single mode propagation of an optical wave down a single mode fiber, comprising an element such as a pixelated liquid crystal element, capable of spatially changing the phase across the cross section of an input optical signal. Such a spatial phase change is equivalent to a change in the mode structure of the propagating wave. The signal propagating in the single mode output fiber is attenuated in accordance with the extent to which higher order modes are mixed into the low order mode originally present. When the mode is completely transformed to higher order modes, the wave is effectively completely blocked from entering the output single-mode fiber, and the attenuation is high. The level of attenuation is determined by the fraction of the wave which is converted to modes other than the lowest order mode, and is thus controllable by the voltage applied to the pixels of the liquid crystal element. | ||||||
