Abstract:
A system capable of tuning a wavelength and an intensity of an output light, comprising:an input end for receiving a first optical signal and a second optical signal; a first output end; a second output end; a first rotatable optical device for allowing said first optical signal to pass through and reflecting said second optical signal when the angle of said first rotatable optical device is adjusted; a second rotatable optical device for allowing said first optical signal to be outputted from said first output end, said second rotatable optical device being provided with a plurality of total reflection coatings, and wherein the intensity of said first optical signal outputted from said first output end is changed when the angle of said second rotatable optical device is adjusted; and a third rotatable optical device whose angle is adjusted in accordance with the angle of said first rotatable optical device in such a way that said second optical signal can be outputted from said second output end.
