Laser Driver Amplifiers
High-performance laser drivers for next-generation optical transmitters.
Coherent’s portfolio of laser driver amplifiers - comprising both direct modulation drivers and modulator drivers - delivers precise modulation control, low power consumption, and optimized signal integrity for high-speed optical interconnects.
Built on decades of expertise in laser and transceiver design, our drivers are engineered to produce well-behaved, easily equalizable optical signals, enabling higher data rates and improved system performance across AI, hyperscale, and datacom applications.
From proven designs to next-generation solutions, Coherent helps system designers maximize transmitter performance while minimizing power and complexity.
Key Features
- Modulator drivers with high output swing and well-behaved frequency response that simplifies equalization.
- Directly Modulated Laser (DML) drivers for a wide range of lasers (DFB, VCSEL, BH), providing programmable bias,
- modulation amplitude, and burn-in current.
- Output signal monitoring and control functions, including optical feedback for DML drivers.
- Deliver high-quality transmit signals while optimizing power efficiency and solution cost.
- Fully validated in production-grade optical transceiver environments.
