Device and method for selecting optical pulses

摘要

The device has an optical waveguide (105) for guiding an optical radiation along an axis (104), and two electro-optical modulators (101, 102) for modulating optical transparency of the waveguide. The modulators are arranged one after other along the axis of the waveguide. Control circuits (300, 301) i.e. driver circuits, drive the modulators in a temporal delayed manner, and a carrier substrate is made of a semiconductive material. The waveguide and the control circuits are arranged on the substrate. The modulators are arranged between a light input facet (100) and a light output facet (103). An independent claim is also included for a method for selecting optical pulses with improved edge steepness.
