The output of red (∼ 650 nm) light emitting polymer DFB lasers can be modulated by exposure to infrared (∼ 1.3 μm) control pulses that de-populate the S1 level (see figure). This offers the prospect of an effective wavelength conversion between silica and polymer optical fibre communication wavelengths.
