1mW Single-mode VCSEL with Stable Performance Over Temperature
As a VCSEL manufacturer, Ace Photonics designs 1mW single-mode VCSEL sources for customers who need stable, low-noise light in demanding environments. Our devices combine single-transverse-mode emission with robust thermal design, delivering reliable output power and wavelength stability from the lab bench to harsh field conditions.
Wide Operating Temperature Range
Compared with typical multi-mode devices, our single-mode VCSELs are engineered for a significantly broader operating temperature range. This performance is rooted in:
Carefully optimized vertical resonant cavity structure
Advanced current confinement and thermal management
Tight control of epitaxial growth and device processing
For 1mW single-mode VCSELs in the 790/795 nm and 890/895 nm ranges, the device structure is tuned to maintain efficient lasing across elevated ambient temperatures. In system integration, this means the laser can remain on-spec without complex external temperature compensation, supporting compact designs in quantum sensors, magnetometers and industrial instruments working up to high ambient temperatures.
High Wavelength Stability
Single-mode operation is at the core of wavelength stability. Only one transverse mode is allowed to lase, which results in:
A narrow, well-defined emission peak
Reduced mode hopping over temperature and drive current
Predictable behavior when the device is coupled into filters, cavities or resonant cells
For 1mW single-mode VCSELs, this stability is crucial in applications such as:
Atomic and quantum sensing (e.g., pumping alkali vapor cells near 795 nm or 895 nm)
High-precision spectroscopy that requires repeatable wavelength positioning
Optical communication and sensing links where drift directly impacts system calibration
The result is a compact laser source that can hold its wavelength over a wide thermal range, reducing re-alignment and re-calibration time in production systems.
Polarization Stability
In many coherent and sensing systems, polarization is just as critical as wavelength. The symmetric cavity and single-mode design of our VCSELs help maintain a stable polarization state over temperature and time.
For 1mW single-mode VCSELs used in:
Coherent or heterodyne detection schemes
Polarization-sensitive spectroscopy
3D sensing or structured-light illumination
a well-controlled polarization state improves signal-to-noise ratio and simplifies downstream optics. In practice, this reduces the need for extra polarization-cleanup components, allowing more compact and cost-effective modules.
Power Classes and Wavelength Coverage
Ace Photonics offers single-mode VCSELs in different power levels, including 0.1 mW, 1 mW and higher-power variants, with standard wavelengths around 790/795 nm and 890/895 nm. These devices are available as die and in multiple packaging options, including TO headers, SMD formats and non-magnetic packages for ultra-sensitive quantum sensing.
Our single-mode VCSEL portfolio spans approximately 750–900 nm, allowing system designers to select the optimal wavelength for specific absorption lines, filters or detector responses while maintaining the same manufacturing platform and reliability level.
Packaging Options for Real-World Systems
For the 1mW single-mode VCSEL, we support a range of integration-ready formats:
Bare die for direct integration into custom photonic assemblies
TO-style and ceramic packages, including non-magnetic versions for atomic magnetometers and quantum devices
SMD packages suited to compact PCBs and wearable or embedded electronics
Through integrated packaging, the VCSEL chip can be combined with temperature sensors and, where required, TEC elements to achieve tighter on-package temperature control without large external mounts. This is especially beneficial in miniaturized systems where space and power budgets are limited.
Target Applications of 1mW Single-mode VCSEL
Thanks to the combination of wide temperature range, wavelength stability and polarization control, 1mW single-mode VCSELs from Ace Photonics are used across a variety of fields, including:
Quantum and atomic sensing – such as chip-scale magnetometers, atomic clocks and other quantum devices
High-precision instruments and spectroscopy that require narrow linewidth sources at well-defined wavelengths
Biomedical and oxygen sensing where stable VCSEL emission enhances measurement accuracy
3D sensing and imaging modules that benefit from efficient, compact and stable light sources
Optical communication and interconnects that demand predictable optical characteristics over long lifetimes
In each of these use cases, the 1mW single-mode VCSEL serves as a reliable building block, supporting tight system specifications while keeping overall size and power consumption low.
