Laser diodes are essential components in modern optical systems, offering high efficiency, compact size, and long lifespan compared to traditional lasers. Among these, quantum well laser diodes stand out as the mainstream choice in the market, thanks to their low threshold current and high output power. These features make them ideal for applications requiring reliable and efficient performance.

In the bidirectional optical receiver’s back-transmission module, the quantum well laser diode serves as a critical light source for uplink transmission, enabling seamless optical communication. This advanced laser diode technology not only improves energy efficiency but also ensures consistent performance over extended periods.
