In this paper, a 1D photonic crystal waveguide and plasmonic compound nano-system are utilized to design hybrid photonic-plasmonic device for enhancement of light–matter interaction. Strongly localized light waves in very small volume intensify the optical field, via surface plasmons due presence gold nanoparticle, which interacts with resonator’s cavity mode while nanobeam ensures high tempora...

oral malignant melanoma (omm) accounts for 5% of all oral malignancies. it is a rare aggressive neoplasm usually found on the hard palate and gingiva. the etiology is unknown, but tobacco and chronic irritation are suggested as probable causative factors. over 30% of the cases have been reported to arise from pre-existing pigmented lesions. a biopsy is required to establish the diagnosis and th...

Abstract Background Robot-assisted laparoscopic transverse colon tumor surgery requires precise localization. The purpose of this study was to evaluate the safety and efficacy nano-carbon titanium clip combination labeling methods in robot-assisted surgery. Methods From January 2018 2019, clinical data 16 patients who come from FuZhou, China underwent preoperative combined with cancer were retr...

This chapter reviews the fundamental optical properties and applications of photonic molecules (PMs) – photonic structures formed by electromagnetic coupling of two or more optical microcavities (photonic atoms). Controllable interaction between light and matter in photonic atoms can be further modified and enhanced by the manipulation of their mutual coupling. Mechanical and optical tunability...

We analytically show that an incident light can be almost completely diffracted into the -1(st) order in wide-angle and broadband by suitably designed thin metallic nano-gratings with simple rectangular cross sections. Such extraordinary optical diffraction results from the excitation of localized cavity modes and exists even when the grating period is modulated in a broad range. By modulating ...

We show how to apply the Leggett-Garg inequality to opto-electro-mechanical systems near their quantum ground state. We find that by using a dichotomic quantum nondemolition measurement (via, e.g., an additional circuit-QED measurement device), either on the cavity or on the nano-mechanical system itself, the Leggett-Garg inequality is violated. We argue that only measurements on the mechanical...

ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. the importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. up to now, different materials such as z...

There is intense and growing interest in one-dimensional (1-D) nanostructures from the perspective of their synthesis and unique properties, especially with respect to their excellent optical response and an ability to form heterostructures. This review discusses alternative approaches to preparation and organization of such structures, and their potential properties. In particular, molecular-s...

A novel approach for RF fingerprinting using a simple microwave passive device is proposed. This device is a multi-port cavity resonator filled with a dielectric material mixed with randomly-distributed microor nano-particles. Such structure generates a typical Physical Unclonable Function (PUF) that can be perfectly used for storing and protecting secure information. This mixture guarantees a ...

Two fundamental laser physics phenomena--dissipative soliton and polarisation of light are recently merged to the concept of vector dissipative soliton (VDS), viz. train of short pulses with specific state of polarisation (SOP) and shape defined by an interplay between anisotropy, gain/loss, dispersion, and nonlinearity. Emergence of VDSs is both of the fundamental scientific interest and is al...
