Special Issue Information
Dear Colleagues,
We are pleased to announce the upcoming Special Issue on "Novel Advances in Integrated Optics", which will be published in the journal Photonics. Integrated optics has emerged as a promising field that combines optics, photonics, and microelectronics to develop compact, efficient, and multifunctional photonic devices. This Special Issue aims to provide a platform for researchers to share their groundbreaking findings and foster collaborations in this rapidly evolving field.
Integrated optics plays a pivotal role in addressing the growing demand for high-speed, low-power consumption devices and the exponential growth of data communication and sensing technologies. With its potential to revolutionize various industries, including telecommunications, computing, sensing, and quantum photonics, integrated optics has garnered significant attention from both academia and industry.
The Special Issue “Novel Advances in Integrated Optics” seeks to capture the latest research and emerging trends in this field. We invite researchers to contribute their original research articles, review papers, and short communications addressing fundamental challenges, novel design concepts, fabrication techniques, and applications of integrated optics.
Topics of interest for this Special Issue include, but are not limited to:
- Integrated waveguides and nanophotonics;
- Silicon photonics and on-chip photonic circuits;
- Integrated quantum photonics;
- Hybrid integration technologies;
- Photonic integrated circuit design and optimization;
- Integration of active and passive optical components;
- Advanced fabrication techniques for integrated optics;
- Nonlinear optical phenomena in integrated devices.

Abstract: Silicon-photonic modulator is a high-speed photonic integrated circuit for optical data transmission in high-capacity optical networks. Silicon-photonic modulators in the configuration of Mach–Zehnder interferometer, in which PN-junction rib-waveguide phase shifter is inserted in each arm of the interferometer, are studied in this paper because of their superior performance of high-quality optical data generation in a wide range of spectral band and their simplicity in fabrication processes suitable to production in foundries. Design, fabrication, and fundamental characteristics of silicon-photonic Mach–Zehnder modulators are reviewed as introduction to these high-speed PICs on silicon-photonics platform. Modulation speed, or modulation bandwidth in other words, is a key performance item as well as optical loss in application to high-speed optical transmitters. Limiting factors on modulation speed are addressed based on simulation and measurement results on the high-speed silicon-photonic modulators. Electrical resistance–capacitance coupling, which causes optical modulation bandwidth–optical loss trade-off, is most challenging limiting factor which limits high-speed modulation. Expansion of modulation bandwidth is not possible without increasing optical loss in the conventional approaches. A new idea including quantum-mechanical effect in the design of silicon-photonic modulators is proposed and proved in computational analysis to resolve the bandwidth-loss trade-off. By adding high-mobility quantum-well overlayers to side slab wings of the rib-waveguide phase shifter, modulation bandwidth is doubled without increasing optical loss to achieve 200-Gbaud modulation rate.
