Latest Patents
Zheng's latest patents include a DFB laser DC-coupled output power configuration scheme with adjustable voltage difference. This innovative scheme utilizes either an external or internal power configuration unit to provide two electric DC power supplies with a fixed voltage difference for the transmitting unit TX of the DFB laser and the optical transceiver integrated chip. The optimization of the transmitting unit TX involves using low-voltage high-speed transistors and a negative capacitance structure composed of capacitors, which enhances bandwidth. After implementing this optimization, the minimum voltage of the power supply voltage port TVCC of the transmitting unit TX is reduced to 2.7V. This invention effectively resolves issues related to the output eye diagram, which often becomes severely cracked and unusable when tested at high temperatures with traditional DFB laser configurations.
