Photonic Crystal Defect Nanocavities Based on Monocrystalline Yttrium Iron Garnet
Kota Taniguchi, Siyuan Gao, Tatsuya Kitai +5
Monocrystalline yttrium iron garnet (YIG) is a key material for magneto optics and quantum magnonics owing to its high optical transparency, large magneto-optical (MO) effects at r…
Enhanced Third-Harmonic Generation in Diamond Photonic Crystal Slabs via Doubly Resonant Quasi-Bound States in the Continuum
Sangmin Ji, Satoshi Iwamoto, Hideki Gotoh
We propose and numerically demonstrate doubly resonant third-harmonic generation (THG) in a diamond photonic crystal (PhC) slab, in which the fundamental harmonic (FH) and the thir…
Arbitrary Polarization Generation in Magneto-optical Metasurfaces Enabled by Bound States in the Continuum
Siyuan Gao, Guangtai Lu, Satoshi Iwamoto +1
The generation of arbitrary polarization states of light is essential for optical communication and photonic information processing. Photonic crystal and metasurface platforms supp…
Quantum dot single photon source on SiN integrated with coupled crossover waveguides
Akinari Fujita, Hironobu Yoshimi, Natthajuks Pholsen +5
Hybrid integration of InAs/GaAs quantum dot (QD) single-photon sources (SPSs) is a promising approach for introducing quantum light into SiN photonic integrated circuits. However,…
BIC slow light waveguides based on interband coupling
Sae R. Endo, Yuta Tanimura, Takahiro Ito +5
Harnessing bound states in the continuum (BICs) for guiding light in leaky environments has unlocked new possibilities in photonic integrated circuits. BIC confinement enables low-…
Design of Ultrathin Faraday Rotators based on All-dielectric Magneto-optical Metasurfaces at the Telecommunication Band
Siyuan Gao, Tianji Liu, Satoshi Iwamoto +1
Magneto-optical (MO) interactions offer a direct route to nonreciprocal optical devices but are intrinsically weak in the optical domain, posing a major challenge in downsizing MO…
