The cost is 932 usd per unit, the production is 350,000 units. High-Temperature Quantum Dot Lasers refer to quantum dot semiconductor lasers that maintain stable performance even under high operating temperatures. Their core advantage lies in the fact that quantum dots possess strong three-dimensional carrier confinement and a discrete energy level structure, which endows the devices with lower temperature sensitivity (high characteristic temperature T₀), more stable threshold current, and lower power decay. Consequently, these lasers can operate stably in high-temperature environments (such as 85°C or higher) without the need for, or with reduced reliance on, temperature control (e.g., TEC). High-temperature quantum dot lasers are widely used in fields such as data center optical interconnects, in-vehicle optical communications, lidar, and high-reliability communication systems, representing a key technological direction for achieving low-power, high-reliability light sources.

TEC-free Operation

High-temperature quantum dot lasers will increasingly operate without thermoelectric coolers (TEC). Thanks to low temperature sensitivity, they can maintain stable performance at elevated temperatures, reducing system power consumption, size, and cost.

Higher Operating Temperature Range

Future devices are expected to operate reliably at 100°C or above. By improving quantum dot materials and epitaxial structures, these lasers can meet the requirements of harsh environments such as automotive and industrial applications.

Higher Speed and Bandwidth

Driven by AI and data center demand, quantum dot lasers will support higher modulation speeds (e.g., 100G/200G/400G) while maintaining stable operation under high temperatures, enabling high-speed optical communication.

Silicon Photonics Integration

Integration with silicon photonics will be a key trend, enabling on-chip laser sources. Quantum dot lasers are well-suited for silicon integration due to their tolerance to defects, supporting cost reduction and mass production.

Long Lifetime and High Reliability

Reliability under high-temperature operation is critical. Advances in materials and packaging will extend device lifetime, making them suitable for data centers and automotive-grade applications.

Multi-wavelength and WDM Expansion

Quantum dot lasers can support multi-wavelength emission, making them ideal for Wavelength Division Multiplexing (WDM) systems to increase data transmission capacity.

Cost Reduction and Mass Production

With improvements in epitaxial growth technologies (e.g., MBE, MOCVD) and supply chain maturity, production costs will decrease, enabling broader commercialization beyond niche high-end markets.
