Title:
OPTICAL SWITCH ELEMENT DRIVE CONTROLLER
Document Type and Number:
Japanese Patent JP2503864
Kind Code:
B2
Abstract:
PURPOSE: To provide an optical output pulse with a stable time width by arranging the operation timings of the optical switch elements.
CONSTITUTION: A pulse width detection circuit 3 controls an output voltage of a drive circuit 2 to obtain an optical output pulse with a predetermined width by detecting the pulse width of an optical output 14 of an optical switch element 1 so as to change a drive voltage applied to the optical switch element 1 in response to fluctuation of the pulse, width.
