Abstract:
PCT No. PCT/GB94/02239 Sec. 371 Date Mar. 25, 1996 Sec. 102(e) Date Mar. 25, 1996 PCT Filed Jun. 24, 1996 PCT Pub. No. WO95/10870 PCT Pub. Date Apr. 20, 1995An optical pulse sequence is generated by applying a repetitive optical signal to an optical modulator connected in the laser cavity of a mode-locked laser. The pulse sequence in the laser cavity is then output. The repeat period of the repetitive optical signal is set to be equal to, or an integer multiple of, the cavity round-trip time. The laser is thereby driven to output pulses in bit positions corresponding to the non-zero pulses of the input repetitive optical signal. In one example, the output pulse sequence is used to control an optical switch to provide an OTDM programmable multiplexer using optical signals.
