Synchronization of unidirectionally coupled multi-transverse-mode vertical-cavity surface-emitting lasers
The synchronization of unidirectionally coupled multi-transverse-mode vertical-cavity surface-emitting lasers (VCSELs) is numerically studied. It is demonstrated that synchronization can be achieved between each transverse mode of a master laser and its counterpart, a slave laser. This result opens the opportunity for multichannel chaotic communications by use of multi-transverse-mode VCSELs. I...
متن کاملGreatly enhanced modulation response of injection-locked multimode VCSELs.
We report greatly enhanced modulation response of multimode vertical-cavity surface-emitting lasers (MM-VCSELs), for the first time, using optical injection locking. A 3-dB bandwidth of 38 GHz and 54 GHz resonance frequency are achieved using a MM-VCSEL with a 3 GHz free-running bandwidth. We show that transverse mode selection can be attained with optical injection locking through frequency an...

12 ABSTRACT | With edge-emitting GaN-based lasers in commer13 cial systems, attention is shifting to more demanding and re14 warding emitters. These encompass microcavity (MC)-based 15 vertical cavity surface-emitting lasers (VCSELs) and polariton 16 lasers. The impetus centers on applications such as high-speed/ 17 high-resolution laser printing/scanning technology, lighting, 18 and new types ...
متن کاملOptical Interconnects Using Injection-Locked VCSELs
Injection-Locked Vertical Cavity Lasers exhibit drastically enhanced performance. The 3-dB bandwidth can be increased up to 40 GHz, due to a resonance frequency enhancement. Such VCSELs may play a role in future optical interconnects. c © 2007 Optical Society of America OCIS codes: (140.3520) Injection-locked lasers; (250.7260) Vertical cavity surface emitting lasers
متن کاملStrong optical injection-locked semiconductor lasers demonstrating > 100-GHz resonance frequencies and 80-GHz intrinsic bandwidths.
By using strong optical injection locking, we report resonance frequency enhancement in excess of 100 GHz in semiconductor lasers. We demonstrate this enhancement in both distributed feedback (DFB) lasers and vertical-cavity surface-emitting lasers (VCSELs), showing the broad applicability of the technique and that the coupling Q is the figure-of-merit for resonance frequency enhancement. We ha...
