In contrast to a conventional symmetric Lorentzian resonance, Fano resonance is
predominantly used to describe asymmetric-shaped resonances, which arise from the …

We achieve reflection-type bound states in the continuum (BICs) in the compound grating
waveguide structure by tuning the excitation of the guided modes. Assisted by the quasi …

High sensitivity (S) and high quality factor (Q) are desirable to achieve low detection limit in
label-free optical sensors. In this paper, we theoretically demonstrate that single-layer and …

We demonstrate experimentally close to total absorption in monolayer graphene based on
critical coupling with guided resonances in transfer printed photonic crystal Fano resonance …

Miniaturized optical spectrometers have been realized by exploiting conventional working
principles and advanced nanofabrication technology. Especially in the mid-infrared (MIR) …

We study the effect of structural disorder on the transition from the bound states in the
continuum (BICs) to quasi-BICs by the example of the periodic photonic structure composed …

Silicon (Si) has widely been used as an essential material in the modern semiconductor
industry. Recently, new attempts have been actively made to apply Si to a variety of fields …

All-optical switches are among the most important parts of integrated photonics. Ultrahigh
speed and ultralow energy consumption are two necessary indexes of all-optical switches …

We experimentally demonstrate a tunable Fano resonance which originates from the optical
interference between two different resonant cavities using silicon micro-ring resonator with …

We report here the refractive index (RI) sensing using the singly degenerate high quality
factor (Q) modes in photonic crystal slabs (PCS) with the free-space coupled incident beam …
