1. 1064nm VCSEL Bare Die Supply for Packaging and Module Integration
The 1064nm 20mW–3W VCSEL Bare Die Series includes compact low-power multi-emitter chips and a high-power VCSEL array for semiconductor packaging, near-infrared source development and custom optical-module integration.
The available optical-output classes include 20mW, 30mW and 3W. The 20mW and 30mW devices are characterized under QCW pulse conditions, while the 3W model is suitable for CW or QCW application development. The published 2.9W minimum and 3.1W typical output values for the 3W device are specified under a 25°C QCW test condition.
The series provides a typical center wavelength of 1064nm and includes 4-emitter, 6-emitter and 624-emitter configurations. Typical beam divergence is approximately 20°–21° at 1/e², depending on the selected model.
These 1064nm multi-mode VCSEL devices are supplied as unpackaged semiconductor bare dies for conductive die attachment, gold-wire bonding, ceramic-submount assembly, chip-on-board integration, custom VCSEL packaging and application-specific NIR optical-source development.
The different optical-output levels, emitter counts, die dimensions, drive-current requirements and operating conditions allow customers to select a suitable model according to package space, target output, electrical design, thermal path, working distance, detector response and optical-system architecture.

3. Packaging, Optical Module and Application Development
OSAT and Custom VCSEL Packaging
The 1064nm VCSEL bare dies can be supplied for conductive die attachment, gold-wire bonding, ceramic-submount assembly, custom SMD packages, TO-can packages, ceramic laser packages and chip-on-board optical-source integration.
Packaging and integration directions include:
- VCSEL die attachment
- Gold-wire bonding
- Ceramic-submount assembly
- Custom VCSEL packaging
- Custom SMD laser packages
- TO-can laser packages
- Ceramic laser packages
- COB optical-source assemblies
- Multi-emitter VCSEL array modules
- Application-specific 1064nm NIR source packages
The package should be designed according to the selected device’s die dimensions, electrode structure, drive current, forward voltage, emitter count, output level, operating mode and thermal requirements.
The dies are ESD-sensitive semiconductor components. Appropriate electrostatic-control procedures are required throughout storage, handling, die placement, wire bonding, package assembly and testing.
Low-Power Bare Die Packaging
The 20mW and 30mW models use compact die dimensions and relatively low pulse currents. They can support small ceramic packages, compact COB sources, custom SMD development and space-constrained optical modules.
Although these models have lower optical output than the 3W array, die orientation, bond-pad access, pulse-driver conditions, package protection and optical alignment still require package-level validation.
High-Power Ceramic Packaging and Thermal Design
The 3W model requires a package structure capable of supporting a 624-emitter array, 3.5A drive current, current distribution, effective die attachment and a controlled thermal path.
High-power integration should consider:
- Ceramic-submount material
- Die-attach thermal performance
- Bond-wire number and current capacity
- Electrical-path symmetry
- Package and PCB parasitics
- Heatsink structure
- Junction and submount temperature
- CW or QCW operating condition
- Mechanical stress and package protection
- External lens or diffuser alignment
Continuous-wave operation should not be confirmed from nominal optical-output power alone. Package-level thermal performance and output stability must be validated under the intended current, temperature and cooling conditions.
Lens, Diffuser and Beam-Shaping Integration
The bare-die format allows optical-module developers to select the ceramic submount, optical window, lens, diffuser, collimator and mechanical interface according to the final source design.
Possible integration directions include:
- Collimation-lens assemblies
- Beam-shaping optical components
- Diffuser-integrated VCSEL modules
- Lens-integrated NIR sources
- FOV-controlled illumination modules
- Machine-vision auxiliary sources
- Application-specific optical assemblies
The products provide doughnut-shaped, symmetrical far-field output. Final optical performance depends on the selected chip, emitter configuration, beam divergence, package-window geometry, lens or diffuser design, working distance and mechanical alignment.
NIR Sensing, Machine Vision and Active Optical Detection
The 1064nm VCSEL Bare Die Series can support development and evaluation in the following directions:
- Near-infrared sensing
- Active optical detection
- Machine-vision auxiliary illumination
- Camera-related NIR source development
- Industrial optical detection
- Industrial inspection systems
- Short-distance optical sensing
- High-power NIR illumination
- Engineering and research light sources
- Custom optoelectronic modules
Product selection should consider optical-output requirements, drive current, pulse or CW operation, detector response, working distance, required optical field, package space, thermal design and the final signal-processing architecture.
The VCSEL bare die is one component of the completed optical system. Final detection performance, illumination distribution and source reliability depend on the driver, package, thermal path, optics, detector, mechanical alignment and operating environment.

5. Frequently Asked Questions
FAQ 1. What models are included in the 1064nm VCSEL Bare Die Series?
The series includes 20mW, 30mW and 3W optical-output classes. The 20mW model uses four emitters in a 170 ±10μm × 170 ±10μm die, while the 30mW model uses six emitters in a 163 ±10μm × 185 ±10μm die. Both are specified for QCW pulse operation. The 3W model uses a 624-emitter array in a 1075 ±10μm × 1120 ±10μm die and supports higher-power CW or QCW application development.
FAQ 2. Can the 1064nm 3W VCSEL bare die operate in continuous-wave mode?
The 3W device is described as suitable for CW or QCW applications. However, its published 2.9W minimum and 3.1W typical optical-output values are specified at 3.5A and 25°C under a QCW model. Continuous-wave use therefore requires separate validation of the die attach, ceramic submount, bond-wire structure, current distribution, heatsink and package temperature. The customer should not assume that the published QCW output is automatically maintained under continuous-wave operation.
FAQ 3. How should I select and package a 1064nm VCSEL bare die?
Select the model according to target optical output, operating mode, drive current, package space, emitter count, working distance, detector response and required optical field. The 20mW and 30mW chips suit compact pulse-source development, while the 3W array supports higher-output modules with more demanding thermal requirements. All three products require die attachment, wire bonding, ESD control and package protection. External lenses, diffusers or collimators can be added according to the completed optical-source architecture.
