OPTICAL SEMICONDUCTOR DEVICE AND METHOD FOR CONTROLLING DRIVING CIRCUIT

摘要

An optical semiconductor device includes: an electric-optic conversion element that is provided with a diode; and a driving circuit that drives the diode in a forward direction, the driving circuit including a first switching circuit that is provided with a first switch, and a second switching circuit that is provided with a second switch, wherein the first switching circuit constitutes a first signal line that charges the electric-optic conversion element with an electric charge by bringing the first switch into an ON state and the second switch into an OFF state, and the second switching circuit constitutes a second signal line that discharges the electric charge stored in the electric-optic conversion element by bringing the second switch into an ON state and the first switch into an OFF state.

1. An optical semiconductor device comprising:
an electric-optic conversion element that is provided with a diode; and a driving circuit that drives the diode in a forward direction, the driving circuit comprising a first switching circuit that is provided with a first switch, and a second switching circuit that is provided with a second switch, wherein the first switching circuit constitutes a first signal line that charges the electric-optic conversion element with an electric charge independently of the second switching circuit by bringing the first switch into an ON state and the second switch into an OFF state, and the second switching circuit constitutes a second signal line that discharges the electric charge stored in the electric-optic conversion element independently of the first switching circuit by bringing the second switch into an ON state and the first switch into an OFF state.
