Commercialization of VCSELs and VCSEL arrays
SPIE Proceedings, 2004Various aspects relevant for the commerzialization of VCSELs used in data communications and sensor applications are discussed. In particular, reliability results obtained on selective oxide VCSELs and production reliability assurance procedures are discussed.

Manufacturability of VCSEL components and VCSEL products
Conference Proceedings. LEOS'98. 11th Annual Meeting. IEEE Lasers and Electro-Optics Society 1998 Annual Meeting (Cat. No.98CH36243), 2002In this paper, we examine several of the properties of VCSELs that enhance their manufacturability, and we describe how those characteristics may be exploited in the manufacturing environment. The ability to test the lasers while still in wafer form, the enhanced reliability, and the ability to package the laser in traditional LED package styles are ...

Modulation energy efficiency of VCSEL and coupled-cavity VCSEL
IEEE Photonics Society Summer Topicals 2010, 2010We measure the energy per bit (EPB) for the 25-Gb/s implanted holey VCSEL and 12-Gb/s coupled-cavity VCSEL, and discuss the possibilities for the VCSEL to achieve a lower EPB for data center and interconnect applications.

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.

2021 26th Microoptics Conference (MOC), 2021
Nearly 50 years after practical conception, VCSELs are now ubiquitous. Massive investment has been made to scale production, but has it been overbuilt? What are the most viable next commercial influences in the VCSEL market? This paper examines several of the market forces in both supply and demand of VCSELs.

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.

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 ...

SPIE Proceedings, 2014
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 ...
