Transport and modulation analysis of vertical cavity surface emitting lasers (VCSEL)
LEOS '95. IEEE Lasers and Electro-Optics Society 1995 Annual Meeting. 8th Annual Meeting. Conference Proceedings, 2002We present a comprehensive one-dimensional analysis of VCSELs based on self-consistent solution of laser, carrier transport and Poisson equations. Based on gain spectrum calculations and thermal analysis of VCSELs, we investigate the modulation response of VCSELs.

Vertical cavity surface emitting lasers (VCSELs) and VCSEL arrays for communication and sensing
2022Future generations of optical wireless communication and sensing systems require compact, low-cost, reliable, and highly efficient light sources capable of transmitting modulated beams across free space at gigabit per second (Gbps) data rates and pulsed beams with sub-nanosecond rise and fall times.

Red vertical cavity surface emitting lasers (VCSELs) for consumer applications
SPIE Proceedings, 2008There are many potential applications of visible, red (650nm - 690nm) vertical cavity surface emitting lasers (VCSELs) including high speed (Gb) communications using plastic optical fiber (POF), laser mouse sensors, metrology, position sensing.

Time-localized Structures in Vertical-Cavity Surface-Emitting Lasers (VCSELs)
Numerical Simulation of Optoelectronic Devices, 2014, 2014In this presentation we will review the results recently obtained on Time-Localized Structures (TLS) in VCSELs coupled to an external cavity. We show that, when the cavity roundtrip is much larger than the medium timescales, this system exhibits a temporal aspect-ratio large enough to host TLS. Two configurations will be considered.

Temperature Effects on the Power Characteristics of Vertical-Cavity Surface-Emitting Lasers (VCSELs)
2022A numerical analysis on temperature variation effects on the output power (Pout) characteristics of vertical-cavity surface-emitting lasers (VCSELs) is presented in this paper. While previous works in the literature mostly omitting the thermal effects.

Conference on Lasers and Electro-Optics Europe, 1996
The polarisation of the fundamental transverse mode of VCSEL can change when the injected current is altered. Switching of the polarisation associated to the excitation of higher order modes has been observed. It has also been noted that the strain induced during the fabrication causes birefringence in VCSEL.

Pseudo-high-order-mode in vertical-cavity surface-emitting lasers (VCSELs)
SPIE Proceedings, 2002We built a test system to pick up the pattern of light beam from the VCSELs and the EL spectrum simultaneously in order to study the mode behavior when the current applied on the device increased. As a result, we observed that the light spots from the VCSEL seemd to be high-order-mode while its EL spectrum included more than one peak wavelength ...
