“…, where Q = ω 0 /(2γ) is the quality factor. At ω = ω and 2ω, T reaches its maximum value of 1, thus we obtain T max = (2Q cos 2α+sin 2α) 2 1+4Q 2 . In this way the values of α and γ can be determined and the transmittance of the system is obtained.…”

“…[1] FP modes find wide applications in areas such as laser cavities, interferometry, and optical telecommunications, making them a cornerstone in modern optical science and technology. [2,3] In addition to intentionally designed Fabry-Perot structures with highly reflective mirrors, FP modes are also widely present in planar structures such as photonic crystal (PhC) slabs. [4,5] Another important type of modes in PhC slabs is the guided resonances (GRs), [4] where periodic perturbations cause the original guided mode to transition into leaky modes.…”

“…One such example is the exceptional point (EP), a special type of band singularity at which two or more eigenvalues and the corresponding eigenstates coalesce simultaneously. [2,14,15] When the parameters of the system pass through an EP, the energy spectrum and wave functions of the system undergo drastic changes, which give rise to many interesting phenomena, such as unidirectional invisibility, [16] topological chirality, [17,18] and applications in sensing, [19][20][21] lasing, [22,23] topological energy transfer [24,25] and polarization manipulation. [26,27] PhC slabs offer abundant resonance modes for mode coupling, thus EPs can be readily achieved on this platform.…”

Fabry-Perot (FP) modes are a class of fundamental resonances in photonic crystal (PhC) slabs. Owing to their low quality factors, FP modes are frequently considered as background fields with their resonance nature being neglected. Nevertheless, FP modes can play important roles in some phenomena, as exemplified by their coupling with guided resonance (GR) modes to achieve bound states in the continuum (BIC). Here, we further demonstrate the genuine resonance mode capability of FP modes PhC slabs. Firstly, we utilize temporal coupled-mode theory to obtain the transmittance of a PhC slab based on the FP modes. Secondly, we construct exceptional points (EPs) in both momentum and parameter space through the coupling of FP and GR modes. Furthermore, we identify a Fermi arc connecting two EPs and discuss the far field polarization topology. This work elucidates that the widespread FPs in PhC slabs can serve as genuine resonant modes, facilitating the realization of desired functionalities through mode coupling.

Material processing of dielectrics by temporally shaped femtosecond laser pulses will be presented in this chapter. Structures with feature sizes in the sub-100 nm range are created and the motivation for their application in optical devices is given. The properties of our processing method are discussed with respect to the ionization effects of the light-matter interaction and the implemented tailored pulse shapes to address these individually. Experimental results of structures created in dielectric solids are shown. Electron densities in a water jet were studied numerically and by spectral interferometry to confirm a model for light-matter interaction. The application and characterization of fabricated patterns with regard to the implementation of an optical filter element were studied by numerical simulations and experimental methods.

An atomic force microscope (AFM) integrated directly on the facet of a standard single-mode optical fiber is designed, fabricated, and tested. High resolution force sensing is achieved with a Fabry-Perot interferometer made of two photonic crystal (PC) mirrors separated by silicon springs. The device is fabricated with standard MEMS techniques and assembled on the facet of a single mode optical fiber by focus ion beam (FIB) welding and OmniProbe manipulation. We demonstrate that topographic and tip-sample interaction force information can be extracted from its reflected light. The force curve measurement has a resolution of 10pN/Hz 0.5 in a drastically smaller footprint than traditional AFMs, which can enable in-vivo AFM imaging.
