    摘要： An operating system for telescoping a telescopic boom for a crane, particularly a boom having three or more telescoping sections, enabling the boom to be extended and retracted automatically under load according to a predetermined sequence which optimises the load capacity of the boom and the stability of the crane. The boom may be switched rapidly between modes of operation in one of which all of the telescoping sections may extend or retract and in another of which at least one telescoping section is maintained in the fully retracted position.

    摘要： In a ridge waveguide serial interferometer mode conversion is induced by a first mode conversion section, a phase difference between modes is introduced by propagation over a length of waveguide and optical interference is produced following further mode conversion induced in a second mode conversion section. The first mode conversion section has a first radius of curvature, which is equal to a second radius of curvature of the second mode conversion section. The ridge waveguide interferometer advantageously provides an equal phase dependency as a function of temperature.

    摘要： The invention relates to a method of improving the performance of optical receivers within optical transceivers by compensating for crosstalk, both optical and electrical. Optical crosstalk may arise within the optical receiver from a variety of sources including directly from the optical emitter within, indirectly from the optical emitter via losses, and losses of other received wavelengths within the optical transceiver coupled to the optical receiver. Electrical crosstalk may arise for example between the electrical transmission lines of the optical transmitter and optical receiver. The method comprises providing a secondary optical receiver in predetermined location to the primary optical receiver, the optical receivers being electrically coupled such that the crosstalk induced photocurrent in the secondary optical receiver is subtracted from the photocurrent within the primary optical receiver. The method may be applicable to either monolithic and hybrid optical transceivers.

    摘要： An optical signal is produced from a direct modulation resonant cavity device, such as directly-modulated diode laser having an electrode divided into multiple sections. Each section is driven with an electrical waveform such that a time delay is introduced between sections so as to ensure that the different sections reach their peaks at slightly different times.

    摘要： A VCSEG-DFB laser, fully compatible with MGVI design and manufacturing methodologies, for single growth monolithic integration in multi-functional PICs is presented. It comprises a laser PIN structure, in mesa form, etched from upper emitter layer top surface through the active, presumably MQW, gain region, down to the top surface of the lower emitter. Lower electrical contacts sit adjacent the mesa disposed on the lower emitter layer with upper strip contacts disposed atop the upper emitter layer on the mesa top. An SEG is defined/etched from mesa top surface, between the upper strip contacts, through upper emitter layer down to or into the SCH layers. Vertical confinement is provided by the SCH structure and the lateral profile in the bottom portion of the mesa provides lateral confinement. The guided mode interacts with the SEG by the vertical tail penetrating the SEG and evanescent field coupling to the SEG.

    摘要： The invention describes an integrated-photonics arrangement, implementable in a multi-guide vertical integration (MGVI) structure composed from III-V semiconductors and grown in one epitaxial growth run, allowing for the integration of semiconductor optical amplifier (SOA) and PIN photodetector (PIN) structures within a common wavelength-designated waveguide of the plurality of the vertically integrated wavelength-designated waveguides forming the MGVI structure. The integration includes a wavelength filter integrated between the SOA and PIN to reduce noise within the PIN arising from ASE generated by the SOA. In exemplary embodiments of the invention, the wavelength filter is integrated into MGVI structure either within a common wavelength designated waveguide or within the wavelength-designated waveguide. Further in other embodiments the wavelength filter is provided by a thin-film filter abutting a facet of the integrated-photonics arrangement wherein optical signals are coupled by optical waveguides and/or additional optical elements such as a multimode interference device.
