چکیده

We demonstrate a novel cascaded configuration of optically injection-locked (COIL) VCSELs, which enables a wide and tailorable direct modulation bandwidth. Up to 66 GHz bandwidth is achieved using VCSELs with an original, free-running 10 GHz bandwidth. Different configurations of cascading are discussed in detail with the focus on optimizing the modulation bandwidth. We also discuss scaling capability of this technique to achieve tailorable modulation response.

Greatly 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...

Optical 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

Adjustable Chirp Injection-Locked 1.55-μm VCSELs for Enhanced Chromatic Dispersion Compensation at 10-Gbit/s

We demonstrate adjustable negative chirp from a directly-modulated, injection-locked 1.55-μm VCSEL by controlling the injection parameters. Chromatic dispersion tolerance is enhanced by greater than 10X at 10-Gb/s compared to that of a free-running VCSELs. ©2008 Optical Society of America OCIS codes: (230.2035) Dispersion compensation devices, (250.7260) Vertical cavity surface emitting lasers

Strong 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...

Rayleigh backscattering and extinction ratio study of optically injection-locked 1.55 lm VCSELs

The performance dependence of optically injection-locked 1.55 mm VCSELs by downstream signals in a bidirectional optical link on the degree of Rayleigh backscattered signal and modulation depth of the master DFB laser is studied. Such a study is important for operation in bidirectional WDM-PONs. Error-free upstream performance is achieved when the upstream signal to Rayleigh backscattering rati...
