InP-Based Long-Wavelength VCSELs and VCSEL Arrays
IEEE Journal of Selected Topics in Quantum Electronics, 2009Long-wavelength, InP-based, vertical-cavity surface-emitting lasers with buried tunnel junction (LW-BTJ-VCSELs) and VCSEL arrays are presented. Emitting at the telecommunications wavelengths around 1.3 and 1.55 mum, these devices show high modulation bandwidth in excess of 10 GHz over a wide temperature range.

Antiguided VCSELs and VCSEL phase-locked arrays
LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat. No.01CH37242), 2002Coherent emission from the surface makes vertical-cavity surface-emitting lasers (VCSEL) very attractive light sources for many applications. As an efficient means to increase the coherent output power from a large emission aperture, antiguided structures have been studied for the last few years.

Over the last 20 years, nearly 1 billion VCSELs have been shipped, the vast majority of them emitting at 850nm using GaAs active regions, and primarily used in data communications and optical tracking applications. Looking to the future, the ever increasing speed of data communications is driving the VCSEL to evolve with more complex active regions ...

Test of the VCSEL driver based on Verilog-A VCSEL model
2015 International SoC Design Conference (ISOCC), 2015There have been many tries to model vertical-cavity surface-emitting laser (VCSEL) as a 50-Ω resistor. However, it is not accurate to model VCSEL as a 50-Ω resistor due to its nonlinear characteristics. Therefore, Verilog-A is used with the datasheet of the commercial single-mode fiber (SMF) 1550-nm VCSEL and it is compared with the case of not using ...

Microcavity lasers potentially will have ultra-low thresholds in the micro ampere range or even lower. The vertical-cavity surface-emitting laser (VCSEL) structure represents the most straightforwardly produceable device which can scale down to ultra-small cavity dimensions and active material volumes.

Analysis and Control of Optical Modes in VCSELs and VCSEL-Arrays
2013In this thesis, we studied the modal structure and the polarization of the optical field emitted by vertical-cavity surface-emitting lasers (VCSELs) emitting in the short- and long-wavelength domains (0.9-1.3μm). Our study concerns two types of components: single aperture VCSELs and coupled VCSEL-arrays.
