LDX’s Superior Packaging Options:
Our packaging expertise ensures high thermal efficiency for better performance and lifetimes.
Standard Packages:
C-mount, B-mount, chip-on-submount, 9 mm, TO-3, HHL
- Advanced thermal management: Low thermal resistance for improved lifetimes
- Optional TEC, photodiode, or aiming beam available in some packages
Custom Package:
If one of our standard packages is not what you need, let us know.
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 direction
- Squared 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 emitters
- If 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
