Abstract
The present invention relates to a device and a method for selective transmission of an optical signal. It is an object of the present invention to provide a light modulator and a method for light modulation capable of selecting very short optical pulses of up to the femtosecond range with a low repetition frequency, wherein the repetition frequency can be variable in a range between several Hz up to the GHz range. To this end, the device has a first optical waveguide (), a first drive circuit (), a second optical waveguide () and a second drive circuit (), wherein the spacing between a switching element of the first drive circuit () and the first optical waveguide () is less than 3 mm, and the distance between a switching element of the second drive circuit () and the second optical waveguide () is less than 3 mm, and the first optical waveguide () has a first absorber section (), a pulse picker section () and a second absorber section ().
