OPTICAL PROCESSING DEVICE FOR LIGHT RADIATIONS

摘要

The optical processing device for light radiations allows performing non-linear transfer functions in optical guide, that enable realizing devices to treat analogue or digital optical signals. A coupled quantum well modulator is reverse biased by an adjustable dc voltage source through an impedance and light radiations to be processed are sent parallel with the layers composing the modulator guiding zone.
