Abstract

PURPOSE: To improve the performance of a light transmitting/receiving semiconductor device by forming a light emitting portion and a light receiving portion on the same substrate and transmitting and receiving light independently at time.
CONSTITUTION: An n-type Al0.35Ga0.65As layer 2, an Al0.56Ga0.95As active layer 3, and an Al0.35Ga0.65As layer 4 are sequentially laminated on an n-type GaAs substrate 1, the substrate 1 is then polished, and a wafer of approx. 70μm is formed thereon. A Cr-Au electrode 6 having a circular opening is formed on the layer 4 side, and an Au-Ge-Ni electrode 7 is formed on the substrate 1. This substrate 1 is heat treated in H2 to form ohmic electrodes. Then, a groove 8 of 20μm of width is formed through the circular opening to reach the layer 2. Thus, the pn-junction is isolated into light emitting portion and light receiving portion. The light emitting portion E irradiates light modulated according to an electric input signal to couple it to an optical fiber 9. The light receiving portion D receives the light coming from the fiver 9 to generate a photocurrent, which is produced through a resistor R1 as an output signal. Thus, the light is bilaterally transmitted through the optical fiber without particular light circuit element.
