Abstract
An adjusting method for stabilizing optical characteristic parameters applicable to transmitter optical subassemblies with silicon photonic chips is provided. The adjusting method might include: sensing an initial optical signal emitted by the transmitter optical subassembly with first control component, controlling phase setting parameter of the silicon photonic chip with the first control component to change the transmitter optical subassembly from emitting the initial optical signal to emitting a first modified optical signal, transmitting a power target value to second control component when the first modified optical signal conforms to the phase target value and sensing the first modified optical signal with the second control component, and controlling a bias current of the transmitter optical subassembly according to the first modified optical signal and the power target value to change the transmitter optical subassembly from emitting the first modified optical signal to emitting a second modified optical signal.
