摘要： An electro-optical single-sideband modulator (1) comprising:
• an electro-optical substrate (2) ;
• a bimodal optical waveguide structure (3) formed in the substrate (2) to support different optical modes having associated optical frequencies (ω S , ω A ) and optical propagation constants (β S , β A ) and comprising an optical input (IN) to receive an input optical carrier signal having an optical frequency (ω S ), and a pair of optical outputs (OUT1, OUT2) to output corresponding SSB modulated optical signals, each having an optical frequency spectrum with a single side lobe; and
• an electrode structure (4) formed on the substrate (2) to receive an input electrical modulating signal having an associated electrical frequency (Ω) and electrical propagation constant (β Ω ), and to responsively apply an electrical field to the bimodal optical waveguide structure;
wherein the bimodal optical waveguide structure (3) and the electrode structure (4) are so formed that the optical propagation constants (β S , β A ) of the optical modes and the electrical propagation constant (β Ω ) of the electrical modulating signal meet a Phase Matching condition, according to which the optical propagation constant (β A ) of a first one of the optical modes is equal to the sum of the optical propagation constant (β S ) of a second one of the optical modes and the electrical propagation constant (β Ω ) of the electrical modulating signal, so resulting in the energy of the first optical mode being transferred at least partially to the second optical mode, and, as a consequence, in the optical frequency (ω A ) of the second optical mode being equal to the optical frequency (ω S ) of the first optical mode up-shifted of the electrical frequency (Ω) of the electrical modulating signal.

摘要： From a real valued OFDM signal (S 0 (t)) a baseband signal is (S B (t)) derived and converted into a complex single sideband modulation signal (n(t)). This signal is modulated onto an optical carrier (f OC ) to generate an SSB transmission signal (S OT ) having a small bandwidth and carrying the information in the envelope or in the power of the envelope. According to the modulation direct detection is possible. Only a small bandwidth is necessary for the transmission.

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.
