Embodiment 1

[0020] A driver used for single-ended driving of MZM modulators. The MZM modulators can be LiNiO3 MZM modulators, InP MZM modulators or Si-P MZM modulators. Such as figure 1 As shown, the driver 51 in this embodiment includes a triode Q1, a resistor R1, a current source Is, and a power supply Vcc1. The optical signal is input from the input port Lin of the MZM modulator and output from the output port Lout of the MZM modulator. The MZM modulator first The anode of the optical phase shifter of the arm 62 is welded with a first pad 64, the anode of the second arm 63 of the MZM modulator is welded with a second pad 65, and the first pad 64 is connected to a DC power supply Vcc2 through a resistor R2. The second pad 65 is connected to the power supply Vcc2 through the resistor R3, and the second pad 65 inputs a DC signal; the driver 51 is coupled with the MZM modulator through the high-speed capacitor C1, and the RF signal to be modulated is input to the base of the triode Q1, and...

Abstract

The invention relates to the technical field of wireless communication. The invention relates to a driver, in particular to a driver for single-ended driving of an MZM modulator. The driver includes atriode Q1, a resistor R1, a resistor R2, a resistor R3, a high-speed capacitor C1, a current source Is, a power supply Vcc1 and a power supply Vcc2, a first bonding pad is welded to the anode of a first arm optical phase shifter of the MZM modulator, a second bonding pad is welded to the anode of a second arm optical phase shifter of the MZM modulator, the first bonding pad is connected with thepower supply Vcc2 through a load R2, and the second bonding pad is connected with the power supply Vccc2 through the load R3. A radio frequency electric signal to be modulated is input into the base electrode of the triode Q1, the collector electrode of the triode Q1 is connected with the second end of the resistor R1 and the first end of the high-speed capacitor C1, the emitter electrode of the triode Q1 is grounded through the current source Is, and the second end of the capacitor C1 is connected with the first bonding pad. The substantive effects of the invention are that the load resistorof the MZM modulator is used as the pull-up resistor of the driver at the same time, and establishment of a bias-tee circuit structure is not needed; And the power consumption can be obviously reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a driver for single-end driving of an MZM modulator, an optical emission sub-module, an optical transmission module and a DWDM system. Background technique [0002] In order to enrich people's growing data communication needs, the throughput of data centers is increasing, and the distributed network access units vary in distance. In order to ensure that all types of access units can be covered, the industry urgently needs high-speed, long-distance Optical transmission module. However, while the high data rate brings greater data throughput, it will also lead to an increase in the dispersion effect, which will further affect the improvement of the transmission distance. The Mach-Zehnder Modulator (MZM modulator), that is, the MZM modulator, can achieve a higher rate, and the single-end driven MZM modulator can also solve the problem of limited dispersion, so it is ...
