iXblue – MODULATOR BIAS CONTROLLER

ANalog MZ Modulator Bias Controller

Dither-less Automated Modulator Bias Controller

Unlike classical dither signal based bias controllers, the MBC-AN-LAB does not superimpose any tone (dither) signal to the optical modulated wave. They are designed for application where such a tone signal is not desired and typically for analog applications where a high purity carrier is required. They are easy to implement, fully automated with its autoset function. The MBC-AN-LAB is proposed in a compact and smart package.

Highlights – Benefits & Features

  • Dither-less operation
  • Quadrature operating points (Quad+ & Quad-)
  • Turn-Key and standalone Bias Controller
  • Plug & play with build-in couplers

Applications

  • Analog modulation
  • RFoF transmission
  • Optical communications

Main specifications

  • Very high stability on bias point
  • Calibrated version from 760 nm to the L-Band
  • Easy-to-Use Graphical User Interface

Digital MZ Modulator Bias Controller

Continuously Tunable Modulator Bias Controllers

The MBC-DG-LAB is an automatic bias controller specially designed to lock the operating point of LiNb03 Mach-Zehnder modulators and ensure a stable operation over time and environmental conditions.

The MBC-DG-LAB controller is a continuously tunable bias controllers, meaning it allows operation of the controlled intensity modulator at any point of its transfer function and thus can be used for any telecom modulation schemes, such as NRZ, DPSK, RZ,..

The MBC-LAB benefits of an Auto-set operation for the Min, Max, Quad ± modes resulting in a simplified use.

Highlights – Benefits & Features

  • Auto-set bias points (Min, Max, Quad ±)
  • Control of any bias points from modulator transfer function curve
  • Continuous tuning of the operating point
  • USB remote control

Applications

  • LiNbO3, InP, GaAs modulators
  • Digital modulation schemes NRZ, RZ, DPSK,…
  • Pulse applications
  • Analog applications

Main Specifications

  • Operating wavelength: from 600 nm up to 1 600 nm
  • Locking accuracy @Quad: 90 ± 0.5 degree
  • Extinction ratio at MIN mode: 50 ± 0.05 dB
  • Auto-set bias points (Min, Max, Quad ±)

PuLse MZ Modulator Bias Controller

It is well known that the inherent drift of Mach-Zehnder modulators is caused by aging and environmental variations. Thus, when the modulator is used for optical pulse generation (Min bias point operation), the modulator drift causes a radical optical pulse extinction ratio loss.

iXblue MBC-DG-LAB Modulator Bias Controllers (MBC) is designed to compensate the drift and maintain with an exceptional accuracy the modulator bias point to reach a very high optical pulse contrast value and stability.

The MBC-DG-LAB is an automatic bias controller specially designed to lock the operating point of LiNb03 Mach-Zehnder modulators and ensure a stable operation over time and environmental conditions.

The MBC-LAB benefits of an Auto-set operation for the Min modes resulting in a simplified use.

Highlights – Benefits & Features

  • Auto-set bias points (Min, Max, Quad ±)
  • Control of any bias points from modulator transfer function curve
  • Continuous tuning of the operating point
