Topologically protected Fano resonance in photonic valley Hall insulators
Chang-Yin Ji, Yongyou Zhang, Bingsuo Zou +1
Rapidly developing photonics brings many interesting resonant optical phenomena, in which the Fano resonance (FR) always intrigues researchers because of its applications in optica…
