摘要：A semiconductor optical device (e.g. a resonant cavity device in this form of anLED or a laser) comprises a single substrate arranged for emitting light (O) for incidenceon a sample or other element and also responsive to light (D), e.g. of a differentwavelenght, received back from this sample or other element: the device furthercomprises means for monitoring a characteristic (e.g. its current-voltage characteristic)which varies in dependence upon the light (D) received back from the sample or otherelement.
