We show that a buried oxide layer forming a current aperture in an all epitaxial vertical-cavity surface emitting laser has a profound influence on the optical and electrical characteristics of the device. The lateral index variation formed around the oxide current aperture leads to a shift in the cavity resonance wavelength. The resonance wavelength under the oxide layer can thus be manipulate...

We investigate a control of the motion of localized structures (LSs) of light by means of delay feedback in the transverse section of a broad area nonlinear optical system. The delayed feedback is found to induce a spontaneous motion of a solitary LS that is stationary and stable in the absence of feedback. We focus our analysis on an experimentally relevant system, namely the vertical-cavity s...

We demonstrate chaotic mode lasing in vertical cavity surface emitting lasers at room temperature, with an open cavity confined laterally by the native oxide layer. Instead of introducing any defect mode, we show that suppression of lower-order cavity modes can be achieved by destroying vertical reflectors with a surface microstructure. Lasing on chaotic modes is observed directly through colle...

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

A novel method of fabricating compact intra-cavity contacts with high yield for GaAs/AlGaAs-based vertical-cavity surface-emitting lasers is presented. By carefully tailoring the composition of highaluminum content layer, a highly selective Al2O3 etch-stop layer can be formed simultaneously with the oxide aperture during wet thermal oxidation. With this technique, contact metals can be uniforml...
