Whispering gallery mode (WGM) ring resonators, which have recently been established as a platform for producing and controlling quantum states of light, have found a new home for quantum optics, entanglement, and squeezing. It is possible to make photon pairs by spontaneous four-wave mixing by coupling light into a WGM ring resonator, which may then be entangled through non-linear optical interaction. Moreover, by squeezing, the quantum noise in the system may be decreased, resulting in greater accuracy measurements. These quantum phenomena might be used in quantum optics, metrology, and communication. It is feasible to construct a Kerr comb with comb spacing in the THz region by adjusting the dispersion of the resonator. This THz radiation has prospective uses in sensing and imaging, as well as material and chemical research. Moreover, integrating these devices on a chip platform enables shrinking, scalability, and interoperability with existing photonic circuits, bringing up new opportunities for chip-based THz technology. Photonic integrated circuits (PICs), on the other hand, provide a small and scalable platform for combining photon sources, detectors, waveguides, and other components on a single chip. PICs allow the construction of complex quantum optical systems due to their high efficiency, stability, and coherence, and are playing an increasingly vital role in developing the area of quantum optics and opening the way for practical quantum technologies. As a result of integrating integrated resonators onto a chip substrate, downsizing, scalability, and compatibility with existing photonic circuits are enabled, opening up new possibilities for chip- based quantum photonic technology.


Dr. Elham Heidari is a research associate at the University of Maryland collaborating with NIST, specializing in the design and implementation of integrated resonators for nonlinear and quantum optics, with a specific focus on all-optical frequency conversion applications and the development of compact and robust photonic platforms for generating and observing phenomena in Kerr combs. Her work in this field has been published in prestigious academic journals, including Nature SR, Optica, IEEE JLT, and Nanophotonics. With nearly four years of experience working in cross-functional teams and experimental design, Dr. Heidari has developed expertise in the development of photonic interconnect devices, including high-speed short-wavelength semiconductor, plasmonic switches, low dimensional electro-optical modulator, chip-based wideband electromagnetic wave sensing, and spectroscopy in Near-IR and MID-IR regions. She has also successfully collaborated with various agencies to obtain research funding, including DOD, NASA, and the Department of Health and Human Services, where she served as senior personnel. Dr. Heidari holds a PhD and M. Eng in Electrical and Computer Engineering from the University of Texas Austin and Tokyo Institute of Technology, respectively.
