The price of a 200G laser diode can vary widely, typically ranging from a few hundred to several thousand dollars depending on specifications and application.

Pricing Overview

Laser diode prices are influenced by several factors including output power, wavelength, spectral properties, package type, and production volume. For example, consumer-grade red laser diodes (630–670 nm) can cost less than $1, while high-power or specialty diodes for telecommunications or biomedical applications can reach tens of thousands of dollars . A 200G laser diode, often used in high-speed optical communications, falls into the specialty category, so expect prices in the hundreds to thousands of USD per unit .

Supplier Options

• Mouser Electronics and DigiKey offer a wide selection of laser diodes from manufacturers like Osram, ROHM, and KYOCERA AVX, with pricing dependent on quantity and specifications .
• Amazon lists lower-power diodes (e.g., 200 mW) for hobbyist or small-scale applications, typically under $50, but these are not suitable for high-speed 200G telecom applications .
• Roithner Laser provides a detailed price list for various wavelengths and powers, which can help estimate costs for specialized diodes .

Key Considerations

1. Wavelength and Modulation Speed: High-speed 200G diodes often operate in the near-infrared range (e.g., 1310 nm or 1550 nm) and require precise spectral properties, increasing cost.
2. Power Output: Higher optical power increases price.
3. Package Type: Single-mode, DFB (Distributed Feedback), or DBR (Distributed Bragg Reflector) diodes are more expensive than basic Fabry-Pérot diodes.
4. Quantity: Bulk orders reduce unit cost, while single-unit purchases are more expensive.

Estimated Price Range

• Low-end / hobbyist diodes: $20–$100
• Telecom-grade 200G diodes: $500–$3,000+ per unit depending on manufacturer and specifications For precise pricing, it is recommended to contact distributors like Mouser or DigiKey with the exact specifications of the 200G laser diode required.
