| Abstract: | A driving circuit was designed for the electro-optical phase modulator, according to its structural characteristics. The circuit consists of OP37 and PA84. It is simple, but stable. The peak-to-peak value of the circuit’s output voltage is up to 200 V within the frequency range of 0 to 280 kHz. Phase compensation was designed for the output signals, and then an optical phase modulation experiment was conducted. The shift of interference fringes caused by the change of driving voltage imposed on the electro-optical modulator was observed by a photodetector. |
| Keywords: | coherent combination electro-optical modulation driving circuit phase compensation |
