LDX's Flexible Fast-Axis Collimation (FAC) Lensing Options:

Our lensing expertise ensures the light is where you need it.

  • Standard Fast-axis collimation (FAC) Options:Best Collimation – Less than 1° divergence in the fast axis directionSquared Beam – Matches the fast-axis to the slow-axis divergence
  • Tailored Fast-axis collimation (FAC):You provide the specifications needed

LDX's Advanced Soldering Techniques:

Soldering is selected and executed for optimal thermal/electrical performance and application-specific reliability.

  • Flux/void-free, high-precision bonding for minimal thermal resistance
  • Soft solder (In): Preferred for best thermal resistance
  • Hard solder (AuSn): Preferred for high-temperature, or when additional soldering steps are required.

LDX's Robust Hermetic Sealing Technology:

Hermetic sealing protects diodes enabling long-duration operation in harsh environments.

  • Hermetically sealed window packages prevent moisture/contamination ingress

LDX's Tailored Solutions:

  • Electrically isolated options mitigate grounding conflicts (e.g., positive package on negative-ground systems)
  • Devices designed for vacuum, radiation, and thermal extremes
  • Emitting Area (Emitters)Most wavelengths are available in 50, 100, 150, and 300 um emittersIf you need something different, let us know.

Custom Packaging:

  • If you need your laser diode chips packages, we can do that.

LDX's Proven Reliability Assurance:

Rigorous in-house qualification delivers failure rates far below industry averages across thousands of deployed units.

  • Every wafer: Extensive qualification and life testing
  • Every device: 100% burn-in + individual electro-optical characterization (data supplied)
  • Extended options: Higher-temperature or extended burn-in, shock/vibration, prolonged life testing, environmental testing

LDX's Unmatched Customization Flexibility:

We specialize in tailored solutions from wafer to finished package, enabling exact-fit integration for unique requirements.

  • Wafer/EPI: Custom wavelengths, emitter sizes, output powers
  • Chip/bar design: Optimized for gain, efficiency, or specific applications
  • Full add-on suite: TEC, photodiode, fiber coupling, hermetic isolation, custom optics
  • Collaborative process: From inquiry through prototype to production
