製品概要 ：

Mach Zehnder structures enable efficient modulation of electrical data signals onto optical carriers but require accurate control of the phase delay set point (DC BIAS) to achieve optimal results. DC BIAS voltages typically drift over time and temperature so that continuous optimization during operation is required.

For Dual Polarization IQ transmitters, this task becomes particularly tedious since nested structures of 6 Mach-Zehnders are required to modulate a single output carrier. Therefore, adjusting 6 interdependent DC BIAS voltages based on a single feedback signal requires a lot of experience and knowledge.

The ID Photonics Automatic Bias Controller (ABC) is designed to automatically find and lock the operating point of Mach-Zehnder modulators to ensure stable optimal performance over time and environmental conditions by a click of a button. By using our controller, you have one thing less to worry about so that you can focus on generating optimal results instead wasting time to tweak BIAS voltages.

製品概要 ：

The Optical Multi-Format Transmitter (OMFT) is a fully integrated optical frontend instrument that converts electrical RF signals into Dual Polarization IQ modulated optical signals.

At a bandwidth of up to 60 GHz, this device provides unparalleled signal fidelity for research in next generation multi-level transmission formats even at high symbol rates beyond 100 GBaud/s in the Terabit/s single carrier regime. It is suitable as reference transmitter for receiver characterization or reference transmitter setups.

The unit is easily interfaces to Arbitrary Waveform Generators (AWG) and Pulse Pattern Generators (PPG).

The unique RF amplitude / modulation format independent automated BIAS control allows users to apply customized RF input signals without requiring manual tweaking of parameters and guaranteeing operation at the optimal operating point. This enables long-term stable operation and automated switching between modulation formats.

Bandwidth explosion requires pushing the envelope of next generation transmission systems to new capacity limits using high-order complex modulation formats, such as 16-QAM and flexible channel grid systems to allow for closer channel spacing and ultimately higher system capacity.

ID Photonics and Fraunhofer Heinrich Hertz Institute jointly developed a modular test solution that provides researchers and engineers a comprehensive way to design and test future ultra-high capacity network architectures for the coherent transmission era using various modulation formats and channel configurations with unsurpassed ease of operation.

This joint development consists of an optical multi-format transmitter that enables a flexible generation of optical data signals with various modulation formats (PSK, QPSK, 16-QAM, etc.) f.

製品概要 ：

Our “PMUX” solution is the ideal choice if your application requires ultra-high channel counts and low insertion loss budged for multiplexing. It features a polarization maintaining AWG to multiplex channels on ITU grid with low insertion loss even for high channel count systems while polarization of each laser line is preserved. Stable output polarization of all laser lines allows for arbitrary modulation of a channel comb using Mach-Zehnder structures to emulate DWDM spectra as depticted below.
