(a) Equivalent circuit of the LD chip. Rc and Cc are the series contact resistance and parallel capacitance, depicted in the red-colored dotted line. Termination 1 refers to the test port of the experimental equipment. The chip network includes an intrinsic LD cascaded with Rc and Cc. (b) Equivalent circuit of the packaged LD. L1, L2 and C1, C2 are the inductors and capacitance originating from the TO lead depicted in the black-colored dotted line. L3 and R1 are the inductor and resistance originating from the bonding wire, depicted in the blue-colored dotted line. s1p refers to the LD chip. Termination 2 represents the test port of the experimental equipment.
