Patent ID: 7144788

Claim:
A method for manufacturing a transmitting optical sub-assembly including a semiconductor light-emitting device and an insulating carrier, a transmission line and a floating pad being formed thereon, said method comprising steps of: (a) mounting said semiconductor light-emitting device on said insulating carrier, and wire-bonding said light-emitting device to said transmission line and said transmission line to said floating pad with a bonding-wire; (b) testing in static said semiconductor light-emitting device by probing said floating pad; (c) removing said bonding-wire connecting said transmission line to said floating pad; and (d) testing in dynamic said semiconductor light-emitting device by providing a modulation signal on said transmission line, wherein after said step (b) and before said step (c), said method further comprises a step of burning in said semiconductor light-emitting device under an intensive condition.
