VERTILAS InP VCSEL Technology: Vertilas has pioneered InP based long wavelength (lw)
VCSELs by developing lasers with an optimized thermal design and excellent single mode
behaviour. These VCSELs feature a dielectric bottom mirror, a
buried tunnel junction (BTJ), a gold substrate acting as heat sink, a
multi quantum well (MQW) active region and optimized waveguide
design. The material structure and design enable the production of
lasers with wavelengths from 1.3 ?m to 2.3 ?m. Fig.1: Cross section of InP VCSEL
NIR VCSEL for Sensing: Tunable diode laser spectroscopy can be deployed in a broad
range of applications to measure many gas species. These gas detection systems require tunable
lasers to scan the absorption lines of the various gases. The electrical and optical characteristics of
a Vertilas laser for methane (CH4) detection are shown in the graphs below. This class 1 laser
features an extremely low power consumption of typ. 10mW (Fig. 2a), an optical power of max. 2
mW (Fig. 2a) and a wide current tuning range of 4 nm (Fig. 2b).

High Data Rate VCSELs: Optical data communications systems for single mode fiber
applications realize transmission speeds of 100 Gbps and 200 Gbps by modulating lasers at 25
Gbps or higher. These lasers require a high bandwidth and excellent single mode performance.
Vertilas has developed high data rate lasers by optimizing the InP VCSEL design with a bandwidth
up to 17 GHz, high max. optical power of 4 mW and a side mode suppression ratio (SMSR) of 40
dB. Single mode VCSELs for 1.3 ?m and 1.55 ?m have been demonstrated with a modulation
performance of 25 Gbps to 50 Gbps. The graphs in fig. 4 show the electrical, optical, spectral and
bandwidth parameters.
