METHOD OF MANUFACTURING OPTICAL TRANSMITTING ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a small optical transmitting assembly capable of performing cheap and high speed drive and an optical transceiver containing the optical transmitting assembly.

SOLUTION: The optical transmitting assembly loads an electronic cooler on a metal base plate, and loads a semiconductor light emitting diode on this electronic cooler through an insulating substrate. Primary and secondary laminated ceramic boards are provided so as to surround the electronic cooler. A control signal of d.c. or low frequency to the semiconductor light emitting diode is supplied to the semiconductor light emitting diode through the primary laminated ceramic board. A high frequency driving signal of the semiconductor light emitting diode is supplied to the semiconductor light emitting diode with a complementary signal having a reversed phase through an internal layer wiring of the secondary laminated ceramic board and the insulating substrate. A semiconductor light receiving element monitoring an output light-intensity of the semiconductor light emitting diode is loaded on the secondary laminated ceramic board. A line for transmitting a high frequency signal from a driving IC loaded outside the optical transmitting assembly to the semiconductor light emitting diode can be provided in a substantially straight line and shortest path.
