Special Issue Information

Dear Colleagues,

Photonic slot waveguides, which are formed by two high-index rails separated by a low-index nanometer-size slot, exhibit the unique property of confining light through total internal reflection in an ultra-thin low-index region. Since 2004, when they were conceived and experimentally demonstrated, slot waveguides have been the topic of an intense research effort motivated by their potential applications in the field of sensing, nonlinear optics, electro-optic modulation/switching, polarization splitting/rotation, and optical amplification/lasing. To scale dielectric slot waveguides, plasmonic slot waveguides with several configurations were experimentally demonstrated. Research activity on these guiding structures is quickly rising and promising results have been already achieved.

This Special Issue will provide a forum for the last research activities in photonic and plasmonic slot waveguides and their applications. Theoretical and experimental papers are solicited in, though not limited to, the following areas:

  • Photonic and plasmonic sensors based on slot waveguides;

  • Optical manipulation of nanoparticles and biomolecules by slot waveguides;

  • Slot waveguide-based nonlinear photonic devices;

  • Silicon-polymer hybrid slot waveguide modulators;

  • Polarization splitters and rotators based on slot waveguides;

  • Optical amplifiers, light emitting diodes, and lasers based on slot waveguides;

  • Mode converters for light coupling into photonic and plasmonic slot waveguides;

  • Slotted photonic crystal waveguides and their applications;

  • Plasmonic and terahertz slot waveguides and relevant devices;

  • Slot waveguide-enabled thermal independence in microphotonic devices;

  • Slot waveguides for on-chip quantum optical circuits;

  • Emerging material for slot waveguides;

  • Novel configurations of slot waveguides;

  • New applications of slot waveguides in short-range interconnects, telecommunications, microwave photonics, and sensing

A ring resonator is a basic component of traditional photonic integrated circuits (PIC), which has been, however, found difficult to be applied efficiently in high-compact plasmonic metal-insulator-metal (MIM) systems. Here, based on a plasmonic band-stop filter with a square ring resonator (SRR), a novel side-coupling method is introduced both numerically and theoretically to achieve a drop in the resonant wavelength in the SRR with considerable efficiency. By introducing the reflector structure, the performance can be appreciably improved. Besides, this structure also has potential for sensing and switching. Finally, a dual demultiplexer based on SRRs is realized at telecommunication wavelengths with comparable performance, which makes it possible to apply ring resonators in on-chip plasmonic wavelength division multiplex (WDM) networks. This work is valuable for PIC design, and will promote the on-chip plasmonic system progress. Full article
