Pulse MZ Modulator Bias Controller

Overview

Mach-Zehnder drift caused by aging and environmental changes destroys pulse extinction ratio at the MIN bias point. Exail MBC-DG-LAB-based pulse bias control locks and holds the MIN point, preserving high extinction ratio for optical pulse generation from 760 nm up to 2200 nm.

Key features

• Auto-set bias points (MIN, MAX, QUAD ±)
• Continuous tuning of the operating point
• USB remote control
• Operating wavelength from 760 nm up to 2200 nm
• LiNbO3, InP and GaAs modulators

Specifications

• Operating wavelength: 760 nm to 2200 nm
• Locking accuracy @ Quad: 90 ± 0.5 degree
• Extinction ratio at MIN mode: 50 ± 0.05 dB

Applications

• Optical pulse generation
• High-extinction-ratio pulse chains
• LiNbO3 modulator stabilization
