Embodiment Construction
[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples serve to illustrate the present invention, but do not limit the scope of the present invention.
[0033] figure 2 It is a structural diagram of an embodiment of the dual-output intensity modulator used in the present invention, which is a non-push-pull structure, including two RF input ports 31, 32, a DC bias port 33 and two optical output ports 34, 35. The amplitude and phase of the two RF input signals can be set as required, but in order to introduce chirp components, the phase difference between the two signals cannot be set to 180 degrees. In one embodiment, one of the radio frequency input ports is used, and the other radio frequency input port is matched with a 50 ohm resistor, the bias point can be set according to actual needs, and the modulated optical signal is divided in...
