1. 665nm 9mW VCSEL Bare Die for Packaging and Module Integration

The 665nm 9mW VCSEL Bare Die is a 6-emitter, higher-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 compact six-emitter red VCSEL die provides 9.0mW typ. optical output under a 25mA, 25°C QCW test condition. Its 163±10μm × 185±10μm non-square die footprint supports higher-output visible-red optical-source packaging, higher emitter density, multi-emitter wire-bonding validation and compact red VCSEL module development.
This 665nm 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.

3. Packaging, Optical Module and Application Development

OSAT and Custom Laser Packaging

The 665nm 9mW bare die supports wire-bonding VCSEL projects, ceramic-submount assembly and application-specific laser-device development.
Packaging directions include:
  • VCSEL die attach
  • Gold-wire bonding process verification
  • Custom VCSEL packaging
  • Custom SMD laser packages
  • TO-can laser packages
  • Ceramic laser packages
  • Ceramic-submount optical sources
  • Chip-on-submount assembly
  • Compact COB and optical modules
  • 6-emitter visible-red VCSEL source packages
  • Higher-output red VCSEL modules
  • Compact multi-emitter red VCSEL packages
The 6-emitter structure makes this model suitable for packaging teams that need a higher-output 665nm red VCSEL die with increased emitter density. It can support multi-emitter layout evaluation, bonding-path design, thermal-path verification and compact optical-module integration where a 4-emitter die may not provide enough optical output.

Lens and Optical Module Integration

The device can support lens, collimation and beam-shaping companies developing higher-output visible-red laser-source assemblies.
Possible integration directions include:
  • Collimation-lens assemblies
  • Beam-shaping optical components

  • Lens-integrated VCSEL sources
  • Compact visible-red optical modules
  • 6-emitter red VCSEL source modules
  • Higher-output red-light optical modules
  • Multi-emitter optical-source validation
  • Compact high-density VCSEL source assemblies
For projects requiring a 665nm visible-red light source with higher output and compact emitter density, this device can be used as a bare-die red VCSEL chip option for packaging, collimation, diffusion, beam shaping and optical-module development.

Downstream Application Development

The datasheet identifies sensor light sources, consumer electronic products, machine vision and red lighting as application directions.
The device can also support:
  • Compact visible-red laser modules
  • Alignment and indication sources
  • Optical sensor light sources
  • Engineering and research light sources
  • Machine-vision support illumination
  • Beauty and personal-care prototypes
