The Exail Modulator Bias Controller (MBC) precisely selects and stabilizes the operating point of lithium niobate Mach-Zehnder modulators, keeping it stable over time and temperature. These automated bench-top instruments come in dedicated versions for analog, digital, IQ and pulse modulation.
Key features
- MBC-AN: analog version with dither-less operation for analog links
- MBC-DG: digital version, continuously tunable, supporting NRZ, DPSK and RZ formats
- MBC-IQ: IQ control for carrier-suppressed single-sideband (CS-SSB) operation with harmonic rejection above 40 dB
- Pulse MZ version: drift compensation for high pulse contrast
Specifications
- Wavelength range: 760 to 2200 nm
- Harmonic rejection (MBC-IQ): more than 40 dB
Applications
- Intensity, phase and IQ LiNbO3 modulation setups where the bias point must stay stable over time and temperature
- Analog, digitally modulated and pulsed Mach-Zehnder links
