The transmitter was injected with a constant current of 10 mA by a DC power. The electroluminescence UV light propagates along the waveguide to both ends. The light spot at the left gap maintained a constant brightness, reflecting that the transmitter was emitting a stable light. On the right, a modulated signal of 1 Hz square with amplitude from −8 V to 0 V was applied on the modulator, and the right spot was flashing with a frequency of 1 Hz. This video graphically shows the absorption modulation of UV light by the modulator.
