1. 660nm 7mW VCSEL Bare Die for Packaging and Module Integration
The 660nm 7mW VCSEL Bare Die is a six-emitter, multi-mode visible-red VCSEL chip and red VCSEL laser chip developed for chip-level packaging, die attach, wire bonding, ceramic-submount assembly and custom laser-module integration.
This higher-output red VCSEL die provides 7.5mW typ. optical output under a 15mA, 25°C QCW test condition. Its 163±10μm × 185±10μm die footprint and six-emitter configuration support projects requiring higher optical output and increased emitter density compared with lower-output 660nm bare-die models.
This VCSEL laser 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 and compact optical modules. As an unpackaged semiconductor chip, it requires suitable mounting, bonding, thermal-path, package and optical-integration processes before use in a finished device or module.
