“…Compared to the traditional Mach-Zehnder modulator 3-9 a silicon (Si) ring modulator 10 offers a smaller footprint and a more energy-efficient operation. [11][12][13] Such modulators are used in frequency comb generators, 14 digital links, microwave photonic links (MPLs), 15 and a variety of other applications.…”

Increasing data rates in the wireless access require high-bandwidth signal processing, which might be problematic for electronics. One solution is provided by high-bandwidth photonic signal processing in integrated silicon photonic devices. The transformation of electrical into optical signals and sometimes the photonic signal processing itself require a modulator. Especially silicon photonic ring modulators have the potential to significantly enhance the signal processing performance for large-scale integrated photonic circuits, since they have a very low footprint and power consumption. Nevertheless, densely packed integrated photonic devices show thermal crosstalk, which may lead to problems of heat dissemination in the chips. Here we will show, that a deep trench is a suitable method to avoid this problem. We present simulation results of crosstalk mitigation for ring modulators and show the improvement in the transmission characteristics.

“…Chapter 4 describes the fabrication and EO poling procedures performed in order to prepare EO antenna prototypes. The microfabrication process is based on the work presented in [24] and [51], as it was developed specifically for the available material set. Similarly, the EO poling procedure developed in [11] was foundational to the EO antenna elements presented in this body of work.…”

Electro-optic modulators are an indispensable part of photonic communication systems, largely dictating the achievable transmission rate. Recent advances in materials and fabrication/processing techniques have brought new elements and a renewed dynamic to research on optical modulation. Motivated by the new opportunities, this Perspective reviews the state of the art in integrated electro-optic modulators, covering a broad range of contemporary materials and integrated platforms. To provide a better overview of the status of current modulators, an assessment of the different material platforms is conducted on the basis of common performance metrics: extinction ratio, insertion loss, electro-optic bandwidth, driving voltage, and footprint. The main physical phenomena exploited for electro-optic modulation are first introduced, aiming to provide a self-contained reference to researchers in physics and engineering. Additionally, we take care to highlight topics that can be overlooked and require attention, such as the accurate calculation of carrier density distribution and energy consumption, the correct modeling of thin and two-dimensional materials, and the nature of contact electrodes. Finally, a future outlook for the different electro-optic materials is provided, anticipating the research and performance trends in the years to come.
