1. 680nm 50mW VCSEL Bare Die for Packaging and Module Integration
The 680nm 50mW VCSEL Bare Die is a 21-emitter, high-output, multi-mode visible-red VCSEL chip and red VCSEL laser chip developed for chip-level packaging, die attach, gold-wire bonding, ceramic-submount assembly and custom VCSEL packaging.
This high-output 21-emitter red VCSEL die provides 55mW typ. optical output under a 140mA, 25°C QCW test condition. Its larger 300±10μm × 300±10μm die footprint supports high-output visible-red optical-source packaging, large-array VCSEL die integration, multi-emitter bonding-path design and high-output red VCSEL module development.
This 680nm VCSEL chip is intended for:
- OSAT semiconductor assembly and test providers
- VCSEL and laser-diode packaging companies
- SMD, TO-can and ceramic package developers
- Die-attach and wire-bonding engineering teams
- Ceramic-submount and COB integrators
- Laser-module and optoelectronic-module manufacturers
- Lens, collimation and beam-shaping companies involved in laser-source integration
- Laser bare-die, component and optical-module distributors
- Technical sourcing and second-source development teams
The VCSEL die can be integrated into custom SMD packages, TO-can packages, ceramic packages, ceramic-submount assemblies and high-output optical modules. As an unpackaged semiconductor chip, it requires suitable mounting, bonding, thermal-path, package-design and optical-integration processes before use in a finished device or module.

The device can be supplied as VCSEL die for packaging in:
- Die-attach process development
- Gold-wire bonding verification
- Wire-bonded ceramic-submount assemblies
- Chip-on-submount assembly
- Custom SMD laser packages
- TO-can and ceramic packages
- High-output visible-red optical modules
- Lens and beam-shaping optical assemblies
Compared with the 680nm 5mW, 12mW and 18mW models, the 50mW device is positioned as the 21-emitter high-output option for customers requiring significantly higher optical output, larger emitter count and high-output red VCSEL chip integration. Compared with the 680nm 18mW six-emitter model, the 50mW model uses a larger 300±10μm × 300±10μm die footprint and a 21-emitter layout for high-output optical-source packaging.
