Abstract
PURPOSE:To eliminate troublesome adjustments and deviation in wavelength by using optical systems such as an optical branching and coupling means and an optical waveguide means for delay. CONSTITUTION:When a light pulse is inputted from a light pulse generating means 2 to one input port 11 of the optical branching and coupling means 1, a light pulse which is branched is outputted from one output port 13 first. Branch light outputted from the other output port 14 is delayed through the optical waveguide means 33 for delay, and then inputted to the other input port 12 of the optical branching and coupling means 6 and branched again. This light which is branched again is therefore outputted from one output port 13 after a delay time from the output of the 1st light pulse and light pulses which are branched in order are outputted from one output port 13 after another at intervals of the delay time of the optical waveguide means 33 for delay, so that a staircase-shaped light pulse train is obtained. Consequently, the nonlinearity, etc., of a light emitting element need not be considered and the driving current of the light emitting element is not varied, so troublesome adjustments are not necessary and no deviation in wavelength is generated.
