Patent ID: 7248616

Claim:
A bi-directional transceiver module which respectively transmits and receives a transmitting optical signal and a receiving optical signal through a line of optical fiber, the transceiver module comprising: a 1.3 μm Distributed Bragg Reflection Laser Diode (DBR LD), which includes an active layer which performs light-emission in response to a light at 1.3 μm and a DBR mirror formed near the active layer; a monitoring Photo-Diode (PD), which has a predetermined energy band gap to absorb a light with a wavelength of 1.3 μm and transmits a light with a wavelength of 1.55 μm; an optical signal detection PD, which has a predetermined energy band gap to absorb a signal with a wavelength of 1.55 μm; an insulated area, which electrically isolates the 1.3 μm DBR LD, the monitoring PD, and the optical signal detection PD, respectively; a p-electrode, which is formed in the 1.3 μm DBR LD, the monitoring PD, and the optical signal detection PD, respectively; and a n-electrode, which is a common electrode.
