1. 670nm 4mW VCSEL Bare Die for Packaging and Module Integration
The 670nm 4mW VCSEL Bare Die is a compact 1-emitter, low-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 low-output red VCSEL die provides 4.0mW typ. optical output under a 10mA, 25°C QCW test condition. Its 200μm × 200μm square footprint and single-emitter layout support low-output VCSEL packaging, compact visible-red optical-source packaging and compact optical-module development.
This 670nm 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 compact 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.
