Hintergrund
Um gleichzeitig die Effizienz und Linearität von hochfrequenten Leistungsverstärkern für Drahtlos- und Mobilgeräte zu verbessern, wird am INT der Ansatz eines volldigitalen Senderkonzepts verfolgt. Im Rahmen des von der DFG geförderten Forschungsprojekts „Hochfrequente Mehrstufen-Schaltverstärker im pulspositions- und pulsweitenmodulierten Betrieb zur effizienten Leistungsverstärkung von breitbandigen Mobilfunksignalen“ sollen dazu mehrstufige Schaltverstärker (ML-SMPA) in einer modernen FDSOI-CMOSTechnologie erforscht werden. Um den Dynamikbereich des Schaltverstärkers zu verbessern, wird die Amplitude des gefilterten HF-Signals zusätzlich zur Pulsweite in diskrete Ausgangsspannungs- (ML-VM-SMPA) oder Ausgangsstromstufen (ML-CM-SMPA) kodiert.
Aufgabenstellung

Spezifische Themen/Specific topics
Objective
Simulation, design and investigation of photonic devices.
Background
Silicon photonics enables the integration of complex optical circuits on a single chip and forms the basis for modern applications in optical communications, sensing, and signal processing. In addition to classic single-mode signal processing, mode-division multiplexing is gaining in importance because it allows multiple modes of a waveguide to be used simultaneously.
A fundamental component of a system is a 3-dB splitter, which must precisely and with minimal loss divide the optical power of defined modes into multiple outputs. While single-mode splitters are established, multi-mode splitters pose a particular challenge on SOI.
Your task
In this work waveguides, bent waveguides and tapers has to be investigated. The focus is a deep understanding of the different devices and the behavior in multimode applications. Therefore, various implementation concepts will be studied for the components and examined with regard to losses, crosstalk, and manufacturing tolerances. A promising routing concept is designed, and a layout is created and can be characterized using metrological methods.

Background
Silicon photonics enables the integration of complex optical circuits on a single chip and forms the basis for modern applications in optical communications, sensing, and signal processing. A central element of many photonic systems is the phase shifter, which allows the phase of an optical signal to be precisely adjusted. While active phase shifters rely on electrical or thermal control, passive phase shifters offer a maintenance-free, energy-efficient, and compact alternative based solely on structural and material properties.
Your task
This work aims to design and simulate a passive optical phase shifter to achieve a defined phase shift through a suitable design of the waveguide geometry in silicon photonics. To this end, various concepts will be considered and investigated with regard to bandwidth, temperature, and manufacturing tolerances.

Background
Growing data demands drive the need for scalable and efficient optical communication systems. Space-Division Multiplexing (SDM) enables parallel data channels through distinct spatial modes in few-mode fibers. To realize this, precise mode transformation and coupling are essential. Multi-Plane Light Conversion (MPLC) is a promising approach that uses a sequence of optimized phase masks to transform Gaussian beams into orthogonal spatial modes, such as Hermite–Gaussian and Laguerre–Gaussian. Understanding and simulating this process is key to developing compact, low-loss mode converters for future optical networks.
Your task
This project focuses on the numerical analysis and practical implementation of spatial mode conversion using MPLC. It includes:
- Developing a numerical simulation framework to model Gaussian beam propagation through phase masks.
- Implementing novel phase optimization algorithms to achieve efficient mode transformations.
- Visualizing and analyzing beam evolution along the propagation path and mode coupling efficiency.

Background
Ever increasing data rates require new and exciting optical fiber technologies such as few mode fibers and multicore Fibers. For polarization diverse characterization of those specialty fibers and their corresponding couplers, a precise and wavelength independent linear polarized source is needed. Due to birefringence in optical fibers this polarization is wavelength dependent, and has to be tuned over wavelength.
Your task
This project involves the design and implementation of a high-speed, closed-loop polarization tracking system that integrates analog polarization state measurement with real-time piezoelectric-based control for dynamic stabilization. The technical scope encompasses three primary domains:
- a high-bandwidth analog sensing subsystem for low-latency polarization detection,

Hintergrund der Forschung
Die schnell wachsende Nachfrage nach Rechenkapazität für künstliche Intelligenz erfordert eine Reduzierung des Energiebedarfs von KI-Beschleunigern. Analoge Beschleuniger sind potentiell energieeffizienter als digitale und werden deshalb von Industrie und Wissenschaft erforscht. Am INT haben wir bereits ein rein analoges System entwickelt: zusätzlich zur Matrix-Vektor-Multiplikation ist die Aktivierungsfunktion durch eine analoge Schaltung implementiert. Dadurch wird die Ausgangsaktivierungen der Neuronen direkt weiterverwendet und an die nächste neuronale Schicht geleitet. Die Fläche und Energie für Cache-Speicher entfallen vollständig und die Latenzzeit wird minimiert.

Photonic Integrated Circuits (PICs) have become a key component of modern communication technologies in recent years. They are used in a variety of commercial products, enabling complex optical functions such as pre-filtering and multiplexing. These PICs are typically fabricated on silicon platforms, similar to electronic circuits. To further increase the performance of these devices, the integration of advanced materials, such as subwavelength metamaterials, is essential. Metamaterials offer unique optical properties that are not found in naturally occurring materials, allowing for unique control over light propagation, refraction, and reflection. This enables the realization of highly compact and efficient photonic components, improving the functionality of PICs in applications like optical filtering, beam shaping, and enhanced light-matter interaction.
