Photonic crystal (PhC) nanobeam cavities have attracted increasing attention owing to the advantages of high Q-factor, small mode volume and no limitation of FSR. Various PhC cavities have been developed for optical communications, optical sensors, optomechanics, etc.. We investigate the design, fabrication, and experimental characterization of high quality factor PhCnanobeam cavities on silicon....
In a conventional optical resonator, the resonance transmission spectrum is always a Lorentz line shape, which is symmetrical with respect to the resonant wavelength. Recently, different configurations based on ring resonators [1], surface plasmons [2] and photonic crystal cavities [3] have been demonstrated to have asymmetric line shape, i.e., Fano resonance. Asymmetric profile in Fano resonance...
Silicon photonic crystal (PhC) nanocavity fabricated on a two-dimensional slab is attractive due to their small size and high-Q, which allow us to study optical nonlinearity at an extremely low input power. However, it has been fabricated by using electron-beam lithography, which makes it difficult to use this device for a practical use, due to the low fabrication throughput. Recently we showed that...
One-way light has attracted much attention recently. They have wide range of applications, such as optical isolators and optical diodes. At present, two approaches can be used to realize the one-way light. One is one-way surface waves, which come from chiral edge states of photonic crystals [1, 2]. The other is one-way body waves, which may originate from the parity-time symmetry of a system [3, 4]...
