We have developed novel organic photonic devices which are capable of all-optical ultrafast gain switching for use in data communication networks and lab on chip type applications. We have exploited different kinds of devices such as a solid state film, a doped plastic optical fibre and an optofluidic microchannel. We have achieved ultrafast switching (<150 fs) over a broad wavelength range (100 nm) with a switch on/off ratio of at least 70%.
