摘要： In accordance with various aspects of the disclosure, a method and apparatus is disclosed for increasing waveform bandwidth of a radio frequency waveform during optical double sideband suppressed carrier modulation. An optical modulator is configured to operate in double sideband, suppressed carrier modulation (DSB-SC) mode producing multiple optical sidebands and optical sideband harmonics. Proper selection of the appropriate optical harmonic via optical filter enables the synthesis of ultra-wideband single-sideband, suppressed carrier (SSB-SC) optical waveforms while simultaneously simplifying the radio frequency (RF) circuitry that generates the radio frequency waveform.

摘要： A system (100) for transmitting digital information includes a transmitting apparatus (102) for generating an optical signal bearing digital information, a dispersive optical channel (104), and a receiving apparatus (110) for receiving the optical signal. The dispersive optical channel (104) is disposed to convey the optical signal from the transmitting apparatus (102) to the receiving apparatus (110). The transmitting apparatus includes an encoder (114) for encoding digital information into a series of blocks, each including a plurality of data symbols corresponding with one or more bits of digital information. A signal generator (118) generates a time-varying signal corresponding with each of said blocks. An optical transmitter (136) is arranged to apply the time-varying signal to an optical source (138) to produce an optical signal which includes an optical carrier and substantially only a single information bearing optical sideband in an optical frequency domain, the sideband corresponding with the time-varying signal. The receiving apparatus (110) includes an optical detector (146) for detecting the optical signal to produce a corresponding received time-varying electrical signal. The receiver further includes means (166) for generating a series of received data blocks from the time-varying electrical signal. An equaliser (168) performs an equalisation of received data symbols included in each data block to mitigate the effect of dispersion of the optical channel, thereby enabling the transmitted data symbols to be recovered.

摘要： A phase shift unit (12) provides a prescribed phase difference (π/2, for example) between a pair of optical signals transmitted via a pair of arms constituting a data modulation unit (20). A low-frequency signal f 0 is superimposed on one of the optical signals. A signal of which phase is shifted by π/2 from the low-frequency signal f 0 is superimposed on the other optical signal. A pair of the optical signals is coupled, and a part of which is converted into an electrical signal by a photodiode (3). 2f 0 component contained in the electrical signal is extracted. Bias voltage provided to the phase shift unit (12) is controlled by feedback control so that the 2f 0 component becomes the minimum.

摘要： There is provided a light modulator capable of suppressing a desired component by adjusting light intensity of a modulation signal before multiplexed. The light modulator includes an intensity modulator (12) arranged in a waveguide portion between a multiplexing unit of a first sub Mach-Zehnder waveguide (MZA) among a main Mach-Zehnder waveguide (MZC) and a multiplexing unit (6) of the main Mach-Zehnder waveguide (MZC) and modulating intensity of the optical signal propagating in the waveguide portion. Since a signal intensity of a component to be suppressed (carrier component (f0) or high-degree component (such as secondary component (f0 ± 2fm)) among the output signals from the respective sub Mach-Zehnder waveguides is adjusted to be in the same order, it is possible to effectively suppress the component (phase is reversed) to be suppressed when the light signals from the respective Mach-Zehnder waveguides are multiplexed by the multiplexing unit (6).
