Special Issue Information

Dear Colleagues,

The field of semiconductor photonic integrated circuits (PICs) has seen remarkable progress over the past few decades, significantly impacting various technological domains such as telecommunications, data centers, sensing, and quantum computing. Semiconductor PICs integrate multiple photonic functions on a single chip, leading to enhanced performance, reduced costs, and minimized energy consumption. Innovations in materials, fabrication technologies, and design methodologies continue to drive the evolution of this field. Moreover, the convergence of electronics and photonics on a common platform has opened new possibilities for creating highly efficient and compact devices that outperform their traditional counterparts. With advancements in all of these integration technologies, such as monolithic integration, heterogeneous integration, and new material platforms, the potential applications of PICs are expanding rapidly, from high-speed data transmission to precise biomedical sensing and beyond.

This Special Issue focuses on the latest advancements in semiconductor photonic integrated circuits. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Novel semiconductor materials and devices for photonic integration;
  • Advanced fabrication technologies;
  • High-speed, high-density and low-consumption PICs;
  • Integrated lasers, modulators, photodetectors and others;
  • Photonic–electronic integration;
  • PIC applications in telecommunications and data centers, sensing and imaging technologies, quantum photonics and quantum computing, etc.;
  • Thermal management in PICs;
  • Reliability and packaging of PICs.

We look forward to receiving your contributions.

The transmission spectrum of a twin-waveguide cavity is systematically analyzed based on coupled mode theory, using the transfer matrix method (TMM). The results show that the traveling-wave transmission spectra of the twin-waveguide cavity is entirely determined by the coherent coupling effect involving the parameters of the effective refractive indices of the upper and lower waveguides, the coupling length Lc, and the ratio of the cavity length L to the coupling length (L/Lc). Filters with single, double, or triple-notch filtering could be obtained by choosing an appropriate L/Lc value. When the facet reflection is taken into consideration, the traveling-wave transmission spectrum is modified by the Fabry––Perot (FP) resonance, making it a standing-wave transmission spectrum. As a result, resonance splitting has been observed in the transmission spectrum of twin-waveguide resonators with high facet reflectivity. Further analysis shows that such an abnormal resonance phenomenon can be attributed to the destructive interference between the two FP resonance modes of the upper and lower waveguide through coherent coupling. In addition, narrow bandwidth amplification has also been observed through asymmetric facet reflections. Undoubtedly, all these unique spectral characteristics should be beneficial to the twin-waveguide cavity, achieving many more functions and being widely used in photonic integration circuits (PICs).
