ViBO (VCSEL with integrated Backside Optics)

Single mode VCSEL

Single-mode VCSELs are the perfect choice for demanding sensor applications due to their improved optical characteristics. Higher-order longitudinal and transversal modes are suppressed by the innovative chip design; at the same time, the polarisation is linearly stable.

Gaussian-shaped beam profile

The absolutely symmetrical and Gaussian-shaped beam profile makes the optical design of your application significantly easier.

Low beam divergence

A reproducible divergence angle in the range of 20° (1/e2) or less makes beam guidance easier.

Low spectral width

The laser line with a spectral width of a typical figure of 100 MHz makes this laser perfect for spectroscopic applications.

Low power input

A power input in the range of a few milliwatts allows battery operation in mobile applications.

Beam profile

In the far field, the intensity distribution of the single-mode VCSEL is perfectly Gaussian shaped

LIVT characteristic curve

Low threshold currents and a linear performance across a large temperature range make defining a suitable operating point easier

Spectrum

Higher-order modes are strongly suppressed; the spectrum has an extremely narrow band

Optical encoder for high-precision positioning

Single-mode VCSELs are perfectly suited to use in optical encoders due to their Gaussian-shaped beam profile, their low power input, their long coherence length and their outstanding reliability.

FTIR (Fourier-transform infrared spectroscopy) graphic, TRUMPF Photonic Components

FTIR (Fourier-transform infrared spectroscopy)

Due to the low temperature dependence of the emission wavelength (0.06 nm/K) and the narrowband spectral emission of a typical figure of 100 MHz, temperature-stabilised single-mode VCSELs are particularly suitable as a wavelength reference for FTIR spectrometers.

Oxygen sensors

Single-mode VCSELs are excellent for TDLAS applications (Tunable Diode Laser Absorption Spectroscopy). TDLAS systems benefit from the narrow line width and fine controllability offered by the single-mode VCSEL with TEC.

Highly precise depth sensor

Single-mode VCSEL arrays are supremely suited for highly precise ToF applications (Time-of-Flight). Linear depth measurements ranging from several metres up to 0 mm can be carried out with single-mode VCSEL arrays.

Chip

For high-volume applications and highly integrated sensors, we provide this laser diode as a chip. The laser diodes are supplied as chips on a tape here. This delivery format requires a pick & place or a die-bonding process for processing the laser diodes.

TO46

VCSELs in a hermetically sealed TO46 housing allow easy handling of the laser diode and are suitable for operation in demanding ambient conditions. In addition, a burn-in test is made possible; an integrated Zener diode reduces the ESD sensitivity.

TO46 with TEC

A package with an integrated TEC is suitable for applications that demand a large temperature window or require spectral stabilisation of the laser diode. The Peltier element makes it possible to precisely regulate the laser temperature using the NTC thermistor; due to the hermeticity of the housing, condensation on the VCSEL can be excluded.

ViBO product image, front

ViBO

ViBO stands for VCSEL integrated Backside Optics. This is VCSEL array technology that is advanced, cost-effective and easy-to-integrate using monolithically integrated micro-optical elements. The platform offers a top view that is 5 times smaller compared to other packaged VCSEL solutions. Furthermore, the integrated optics enable an inherently eye-safe system throughout the entire product life cycle. ViBO solutions are particularly interesting for 3D sensor applications in the areas of consumer electronics, automotive and other industrial sectors.
