Room temperature electrically pumped topological insulator lasers

Autor: Jae-Hyuck Choi, William E. Hayenga, Yuzhou G. N. Liu, Midya Parto, Babak Bahari, Demetrios N. Christodoulides, Mercedeh Khajavikhan

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-7 (2021)

Topological insulator lasers offer robustness and efficiency due to their unique properties but usually require cryogenic temperatures or optical pumping. Here the authors demonstrate an electrically pumped topological insulator laser operating at ro

Engineering interaction dynamics in active resonant photonic structures

Autor: Yuzhou G. N. Liu, Omid Hemmatyar, Absar U. Hassan, Pawel S. Jung, Jae-Hyuck Choi, Demetrios N. Christodoulides, Mercedeh Khajavikhan

Publikováno v: APL Photonics, Vol 6, Iss 5, Pp 050804-050804-10 (2021)

The collective response of a system is profoundly shaped by the interaction dynamics between its constituent elements. In physics, tailoring these interactions can enable the observation of unusual phenomena that are otherwise inaccessible in standar

Direct observation of exceptional points in coupled photonic-crystal lasers with asymmetric optical gains

Autor: Kyoung-Ho Kim, Min-Soo Hwang, Ha-Reem Kim, Jae-Hyuck Choi, You-Shin No, Hong-Gyu Park

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-9 (2016)

Non-Hermitian optical systems have been shown to sustain lasing when they go from a PT-symmetric to a PT-symmetry-broken phase. Here, Kimet al. study this phase transition of lasing modes in partially graphene-covered coupled microcavities and show t

A high-resolution strain-gauge nanolaser

Autor: Jae-Hyuck Choi, You-Shin No, Jae-Pil So, Jung Min Lee, Kyoung-Ho Kim, Min-Soo Hwang, Soon-Hong Kwon, Hong-Gyu Park

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-8 (2016)

Flexible, millimetre-scale systems and devices require embedded, reliable micrometre-scale components, which can be challenging to achieve for optical sensors. Here, the authors design a photonic crystal nanolaser and demonstrate its use in measuring

Integration of Single-Photon Emitters in 2D Materials with Plasmonic Waveguides at Room Temperature

Autor: Kwang-Yong Jeong, Seong Won Lee, Jae-Hyuck Choi, Jae-Pil So, Hong-Gyu Park

Publikováno v: Nanomaterials, Vol 10, Iss 9, p 1663 (2020)

Efficient integration of a single-photon emitter with an optical waveguide is essential for quantum integrated circuits. In this study, we integrated a single-photon emitter in a hexagonal boron nitride (h-BN) flake with a Ag plasmonic waveguide and

Lasing in optimized two-dimensional iron-nail-shaped rod photonic crystals

Autor: Soon-Yong Kwon, Seul-Ki Moon, Jae-Hyuck Choi, Se-Hwan Jang, Kwang-Yong Jeong, Hong-Gyu Park, Jin-Kyu Yang

Publikováno v: AIP Advances, Vol 6, Iss 3, Pp 035026-035026-6 (2016)

We demonstrated lasing at the Γ-point band-edge (BE) modes in optimized two-dimensional iron-nail-shaped rod photonic crystals by optical pulse pumping at room temperature. As the radius of the rod increased quadratically toward the edge of the patt

The Superficial Peroneal Nerve Is at Risk during the 'All Inside' Arthroscopic Broström Procedure: A Cadaveric Study

Autor: Sung Hwan Kim, Jae Hyuck Choi, Sang Heon Lee, Young Koo Lee

Publikováno v: Medicina, Vol 59, Iss 6, p 1109 (2023)

Background: The arthroscopic Broström procedure is a promising treatment for chronic ankle instability. However, little is known regarding the location of the intermediate superficial peroneal nerve at the level of the inferior extensor retinaculum;
