NEDA LD4-A is our powerful 4-channel driving engine for active elements such as laser diodes, superluminescent diodes and semiconductor optical amplifiers, and for low resistance heating electrodes. It incorporates by design all safety features required for operation of sensitive optoelectronic loads, and provides up to 4 V compliance voltage and up to 500 mA output current per channel. The channels constitute a quad of independent voltage controlled current sources based on a common-cathode architecture that makes our engine an ideal driving solution for active multi-element chips and PICs.

NEDA LD4Τ is our 4-channel control unit for active elements such as laser diodes, superluminescent diodes and semiconductor optical amplifiers, and for low resistance heating electrodes. It is based on our NEDA LT4-A driving engine to provide up to 4 V compliance voltage and up to 500 mA output current per channel. Compared to NEDA LT4-A, it additionally includes all required digital and mixed-signal elements for autonomous operation, and a TEC controller for the thermal control of a standalone optoelectronic load or a PIC. It is connected to the user equipment (laptop/desktop) via a USB connection, and offers a Python-based GUI for real-time control of the 4 driving channels and the TEC.

Optical equalizer: We are working on a photonic integrated optical equalizer that can be used as an add-on unit in optical transmitters for FSO links and optical interconnects. The optical equalizer has the flexibility to operate in a broad range of rates up to 100 Gbaud compensating for the bandwidth limitations of the corresponding transmission systems. Multi-channel operation is also supported. Its system design and use are based on a patent family filed by Optagon. The preparation of the first prototype was realized with the support of ACTPHAST4.0. System results from the use of the optical equalizer in optical interconnects have confirmed the validity of the concept and the system design. Testing of the optical equalizer in FSO links is the next step.

Active optical sensor: We are also developing an active optical sensor based on the emission, reflection and detection of NIR light. The localization of the reflecting objects and the image reconstruction of the surrounding environment is based on the combination of a time-of-flight (TOF) method with an ultra-fast 2D scanning process on the elevation and azimuthal plane. The ultra-high speed potential of the scanning process is empowered by a disruptive optical phased array (OPA) concept formulated and IP protected by Optagon.

OFDR engine: We are also working on the development of a compact engine for optical frequency domain reflectometry (OFDR). The engine will implement an OFDR scheme based on linear frequency modulation and coherent detection, and will comprise all required photonic parts and companion electronics for the calculation of the Rayleigh backscattering (RBS) from optical fiber spans for distributed acoustic sensing (DAS) applications.
