Abstract:
PCT No. PCT/DE96/00597 Sec. 371 Date Sep. 30, 1997 Sec. 102(e) Date Sep. 30, 1997 PCT Filed Mar. 29, 1996 PCT Pub. No. WO96/30976 PCT Pub. Date Oct. 3, 1996In a self-pulsing multi-section laser having two DFB sections, a Fabry-Perot-like resonator formed from two reflectors and a spacer is integrated into the multi-section laser and optically coupled to at least one DFB section. The spacer has a similar layer structure to the adjacent DFB sections (D1 and D2) but not DFB grid and takes the form of a control section operable electrically separated from the DFB sections. Selection is unnecessary. The self-pulsing two-section DFB laser of the invention with an integrated control section is suitable for optical beat regeneration in high-rate communication systems.
