Special Issue Information

Dear Colleagues,

The relentless evolution of nanotechnology, material science, and theoretical physics has opened up limitless possibilities in the field of photonics. In addition to the well-known variants of photonic devices and circuits, numerous new topologies are being explored worldwide. These emerging and exploratory devices/circuits have unique features that are distinct from conventional counterparts. However, these novel technologies may also introduce unique challenges and necessitate careful co-design towards system-level implementation. With the surging interest in quantum information processing, photonic-quantum technology has recently garnered much attention. Photonic interconnect is being considered and utilized for high-performance systems. Terahertz photonics is becoming more popular in medical diagnosis, security, and wireless communications. There are several such examples of emerging usage for photonic technologies, in addition to the conventional applications. This Special Issue of MDPI’s Photonics takes an interest in publishing notable recent contributions in the general field of photonics.

The topics of interest for this Issue will comprise of (but will not be limited to) the following:

  • Photonic transistors/photonic switches/light valves;
  • Optical amplifiers;
  • Photonic integrated circuits/ quantum photonic circuits;
  • Photonic network on chip;
  • Photonic interconnect;
  • Plasmonics;
  • Novel photonic device structures (laser diodes, LEDs, photovoltaic cells, etc.);
  • Display technologies;
  • Terahertz photonics;
  • Photonic sensors/detectors.

We welcome experimental, numerical, and theoretical works.

III-nitride light-emitting devices have been subjects of intense research for the last several decades owing to the versatility of their applications for fundamental research, as well as their widespread commercial utilization. Nitride light-emitters in the form of light-emitting diodes (LEDs) and lasers have made remarkable progress in recent years, especially in the form of blue LEDs and lasers. However, to further extend the scope of these devices, both below and above the blue emission region of the electromagnetic spectrum, and also to expand their range of practical applications, a number of issues and challenges related to the growth of materials, device design, and fabrication need to be overcome. This review provides a detailed overview of nitride-based LEDs and lasers, starting from their early days of development to the present state-of-the-art light-emitting devices. Besides delineating the scientific and engineering milestones achieved in the path towards the development of the highly matured blue LEDs and lasers, this review provides a sketch of the prevailing challenges associated with the development of long-wavelength, as well as ultraviolet nitride LEDs and lasers. In addition to these, recent progress and future challenges related to the development of next-generation nitride emitters, which include exciton-polariton lasers, spin-LEDs and lasers, and nanostructured emitters based on nanowires and quantum dots, have also been elucidated in this review. The review concludes by touching on the more recent topic of hexagonal boron nitride-based light-emitting devices, which have already shown significant promise as deep ultraviolet and single-photon emitters.

Silicon photomultipliers (SiPMs) offer advantages such as lower relative cost, smaller size, and lower operating voltages compared to photomultiplier tubes. A SiPM’s readout circuit topology can significantly affect the characteristics of an imaging array. In nuclear imaging and detection, energy, timing, and position are the primary characteristics of interest. Nuclear imaging has applications in the medical, astronomy, and high energy physics fields, making SiPMs an active research area. This work is focused on the circuit topologies required for nuclear imaging. We surveyed the readout strategies including the front end preamplification topology choices of transimpedance amplifier, charge amplifier, and voltage amplifier. In addition, a review of circuit topologies suitable for energy, timing, and position information extraction was performed along with a summary of performance limitations and current challenges.

A review of silicon photonics for space applications is presented. The benefits and advantages of size, weight, power, and cost (SWaP-C) metrics inherent to silicon photonics are summarized. Motivation for their use in optical communications systems and microwave photonics is addressed. The current state of our understanding of radiation effects in silicon photonics is included in this discussion. Total-ionizing dose, displacement damage, and single-event transient effects are discussed in detail for germanium-integrated photodiodes, silicon waveguides, and Mach-Zehnder modulators. Areas needing further study are suggested. Full article

We present a fully integrated optical ammonia sensor, based on a photonic integrated circuit (PIC) with a tunable laser source and a hollow-core fiber (HCF) as gas interaction cell. The PIC also contains a photodetector that can be used to record the absorption signal with the same device. The sensor targets an ammonia absorption line at 1522.45 nm, which can be reached with indium phosphide-based telecom compatible PICs. A 1.65-m long HCF is connected on both ends to a single-mode fiber (SMF) with a mechanical splice that allows filling and purging of the fiber within a few minutes. We show the detection of a 5% ammonia gas concentration, as a proof of principle of our sensor and we show the potential to even detect much lower concentrations. This work paves the way towards a low-cost, integrated and portable gas sensor with potential applications in environmental gas sensing. Full article
