Denmark quote for 40G vertical-cavity surface-emitting laser

To obtain a 40G VCSEL for Denmark, you will need to contact specialized suppliers such as Lasermate, Sacher Lasertechnik, or European distributors for pricing and availability.

Overview of 40G VCSELs

A Vertical-Cavity Surface-Emitting Laser (VCSEL) is a semiconductor laser that emits light perpendicular to the wafer surface, making it ideal for short-reach optical communication, such as 40G data center links . VCSELs are commonly used in QSFP+ 40G modules, supporting multimode fiber transmission over distances up to a few hundred meters . They offer low power consumption, high modulation bandwidth, and cost-effective manufacturing, especially for dense data center deployments .

Supplier Options

1. Lasermate – Offers bare dies, packaged diodes, and fully integrated VCSEL modules suitable for data communication, LiDAR, and sensing applications. They provide pre-aligned sources for stable fiber coupling .
2. Sacher Lasertechnik – Specializes in tunable high-power VCSELs for spectroscopy, environmental analysis, and biomedical applications .
3. European Distributors – Companies like RPMC Lasers and Photonics.com list VCSEL modules and arrays from multiple manufacturers, including fiber-coupled and turnkey solutions .

Considerations for a Quote

• Module Type: Determine if you need a bare die, packaged diode, or fully integrated module.
• Wavelength: 850 nm is standard for 40G short-reach multimode fiber; 940 nm may be used for sensing or LiDAR .
• Power Output: Individual VCSELs emit milliwatts, but 2D arrays can reach higher output for specialized applications .
• Delivery & Support: Check if the supplier ships to Denmark and offers technical support or pre-aligned fiber coupling.

Next Steps

To get an accurate price quote in Denmark, contact the suppliers directly via their websites or local distributors. Provide details such as desired wavelength, output power, packaging, and quantity to receive a tailored quotation. For 40G data center applications, most vendors can supply QSFP+ compatible VCSEL modules ready for integration.
