| 英文摘要 | In one embodiment, a driver circuit of a vertical-cavity surface-emitting laser (VCSEL) includes bias current sources, modulation current sources, and a switch component connected to the bias current sources at a first node and to the modulation current sources at second nodes; the switch component is configured to modulate a current from the bias and modulation current sources based on an input signal to the switch component; and the switch component is also configured to provide the modulated current to the VCSEL through a folded cascode transistor. |
