Description by Manufacturer

Rofea’ modulator bias controller is specially designed for Mach- Zehnder modulators to ensure a stable operation state in various operating environments. Based on its fully digitized signal processing method, the controller can provide ultra stable performance.

The controller injects a low frequency, low amplitude dither signal together with bias voltage into the modulator. It keeps reading the output from the modulator and determines the condition of the bias voltage and the related error. A new bias voltage will be applied afterwords according to the previous measurement. In this way, the modulator is ensured to work under proper bias voltage.

Feature：

• Bias voltage control on Peak/Null/Q+/Q−
• Bias voltage control on arbitrary point
• Ultra precise control: 50dB maximum extinction ratio on Null mode;
±0.5◦ accuracy on Q+ and Q− modes
• Low dither amplitude:
0.1% Vπ at NULL mode and PEAK mode
2% Vπ at Q+ mode and Q− mode
• High stability: with fully digital implementation
• Low profile: 40mm(W) × 30mm(D) × 10mm(H)
• Easy to use: Manual operation with mini jumper;
Flexible OEM operations through MCU UART2
• Two different modes to provide bias voltage: a.Automatic bias control
b. User defined bias voltage

Application：

• LiNbO3 and other MZ modulators
• Digital NRZ, RZ
• Pulse applications
• Brillouin scattering system and other optical sensors
• CATV Transmitter

1. MER refers to Modulator Extinction Ratio. The extinction ratio achieved is typically the extinction ratio of modulator specified in modulator datasheet.
2. CSO refers to composite second order. To measure CSO correctly, the linear quality of RF signal, modulators and receivers shall be ensured. In addition, the system CSO readings may vary when running at different RF frequencies.
3. Please be noted that input optical power does not correspond to the optical power at selected bias point. It refers to the maximum optical power that the modulator can export to controller when bias voltage ranges from −Vπ to +Vπ .
