Title: Optical transmission circuit
Inventor: NAGABORI TAKESHI
IPC: H04B10/60
Filed: 2000-07-26
Abstract: PROBLEM TO BE SOLVED: To obtain an optical transmission circuit which is low in power consumption and seldom causes crosstalk to a receiving part when it is formed into a transmitting- receiving module of integral structure together with an optical receiving circuit. SOLUTION: A switching circuit equipped with a first and a second current path is provided, a constant current flowing from the anode to cathode of a light emitting device LD is fed from first current path M1 and M4 in response to emission drive signals, a constant current flowing from the cathode to anode of the light emitting device LD is fed from second current path M2 and M3 in response to non-emission drive signals, and a bias current given to the light emitting device LD is fed from a constant current source. By this setup, when a light emitting device emits light rays, the sum of the bias current and the constant current of the first current paths flows through the light emitting device. When the light emitting device emits no light rays, the difference between the bias current and the constant current of the second current paths flows through the light emitting device.  Therefore, a constant current source current flowing through the switching circuit can be set smaller than that flowing through a conventional current switching, and the optical transmission circuit which is low in power consumption seldom causes crosstalk to a receiving part can be obtained.
